JOTA provides high speed paper slitting rewinding machine which is the best match for your need.

It manufactures a variety of narrow rolls in a short amount of time and it is a fully automatic slitting rewinding machine for your paper.

Moreover, its high productivity surely boosts up your business and you gain much profit.

Let’s unravel the qualities and details of the specific machine.

1. What’s paper slitting rewinding machine?

Paper slitting rewinding machine has a close relationship with all kinds of paper, such as thermal paper, office copy paper, substration paper, craft paper, white paper, etc.

With paper slitting rewinding machine, many kinds of paper parent web or paper jumbo roll could be converted to small rolls for further use.

A slitting machine is a kind of basic flexible packaging equipment, usually composed of the steps of unwinding, slitting cutting, and rewinding to complete the special processing for slitting large rolls of materials into small rolls of materials.

The slitting rewinding machine is a kind of intelligent equipment. One frequency inverter is often used to control the rotation of the main feeding system(NIP roller) and the slitting round disc knife, and the other two frequency inverters respectively control the speed and tension of the rewinding.

The slitting rewinding machine adopts a round disc knife or a straight razor blade for slitting. After unwinding, the mother large rolls must be unwinded, and then a single layer of paper material enters the slitting cutting station, cuts into pre-set data, and then rewinds to different lengths and different widths.

According to the different characteristics and usage of the paper material, we generally divide the slitting machine into many sub-categories such as film slitting rewinding machine, paper slitter rewinder machine, thermal paper roll slitting machine, and adhesive sticky paper roll slitting machine, etc.

Each material is different, there will be corresponding functional differences. Today we will talk about the paper slitting rewinding machine.

As the name suggests, the paper slitting machine is a slitting machine that is professionally used to slit paper or paper cardboard. Of course, there are some special slitting machines such as toilet paper slitting machines and paper tape slitting machines. But in the market, the paper slitting rewinding machine is the majority.

Due to the wide variety of paper mother rolls, we only base on coated paper and white cardboard with gray paper cardboard, which is more common in the printing and packaging field.

Coated paper is a high-quality printing paper made of base paper coated with white paint. It is mainly used for printing the covers and illustrations of high-end books and periodicals. Coated paper is used for landscape photos or photos with rich colors and complex patterns.

Coated paper is a relatively advanced paper, so the substrate of coated paper is high in wood pulp content, wood fiber length is relatively long, paper quality is good, and the thickness is around 70gsm to 320gsm.

Coated paper is a relatively high-level paper, coupled with the characteristics of strong and thick, generally uses active circular knife slitting to cut. This kind of active round cutting method can cut the paper quickly through the high speed of the knife, and create less dust, and the cutting edges are neat.

A paper slitting rewinding machine is a slitting machine specially used for slitting paper and paper board. The width range is from 800mm to 350mm, the unwinding diameter is from 1000mm to 1500mm, and the winding diameter is from 800mm to 1500mm. The speed range is from 200m/min to 500m/min.

Paper slitting rewinding machines are mainly used in printing and packaging plants and paper mills. The slitting rewinding machines used in paper mills are heavy-duty single-shaft slitting and rewinding machines. The winding mechanism adopts two bottom rollers and one upper pressure roller. The single shaft of the rewinding is stuck in it, and the paper enters through the rewinding lower pressure roller, which protects the strength tension of the paper surface very well, so the speed of this machine can be driven from 500m/min to 1000m/min. The high efficiency of the single-shaft slitting machine is of great help to the operation of changing rolls and greatly saves time and labor.

Due to the high speed and efficiency of this slitting method, it is generally adopted by large paper mills. After the paper is calendering out from the coating machine, the width of the large roll of paper will be between 3000mm and 5000mm. Large rolls of paper directly enter the wide-width slitting machine to be slit / converted into various sizes and for resell. The largest paper roll diameter will reach D1800mm.

In conjunction with the work of high-speed slitting machines, pneumatic round

disc knives are generally adopted. A pneumatic round disc knife is a kind of disc knife controlled by pneumatic pressure. It is popular in Europe or Taiwan, and it has been spread to the Chinese market in the past 10 years. Due to its small runout, high precision, and wear resistance, pneumatic knives have been used by high-end equipment. The current size of the air knife is D150 x D80mm, and the hardness HRC is 62-64 degrees.

Due to its simple adjustment and convenient pneumatic closure, the pneumatic round disc knife is very convenient for the adjustment of multiple specifications in paper mills. The most important thing is that due to the advantages of the structure, the pneumatic round disc knife has a relatively small jump during high-speed rotation, and the maximum cutting speed can exceed 1000m/min. . Because of the excellent performance, it is accepted by the majority of the market.

If you are a large printing plant or paper mill, please consider using high-end level pneumatic round disc knives on your paper slitting machine. Although a knife will be costly, it will greatly improve quality and speed control.

In the market, there is another kind of papers, such as white cardboard kraft paper and gray card board paper. Due to its convenience and cost-effectiveness, it is widely used in the packaging field. Compared with coated paper, the wood pulp fiber registration of cardboard is much worse, and more straw pulp is adopted. Because the tensile properties of cardboard are relatively weak.

However, the rollers used in the paper slitting rewinding machine are all steel rollers above D250mm, which have great wrapping properties, so jammed paper is also suitable for this slitting method. Each drive roller is ingeniously designed by mechanical engineers to form a good angle to protect the stretchability of the paper reels.

After entering the rewinding station, the D450mm bottom roller binds the paper cardboard well, ensuring the high tension requirements are maintained during high-speed rewinding and slitting.

When the paper cardboard is cut, a small amount of dust will be generated. If the dust falls on the surface of the paper, it will be carried into the offset press or die cutting machine in the next process. Our engineers specially optimized a pneumatic circular cutter with a dust suction device. It is composed of a closed knife cover and a dust suction fan. When cutting, the dust is automatically collected, which is very efficient and safe.

If you are always troubled by the dust during slitting, please contact our sales team, we will give you great support for the automatic dust collector.

Jota machinery has accumulated considerable experience in paper slitting machines. We have a deep understanding of the characteristics of various papers, especially for the control system of large paper slitting machines. We have our own electrical engineers who can control all the system has its own understanding.

An excellent control system, for a paper slitting machine, is like installing a smart brain, and the control of every small action of the slitter rewinder machine can be precisely controlled by the soft program. All mechanical actions, pneumatic systems, and electrical circuit systems are coordinated with each other, which is efficient and clean.

So when you buy this type of paper slitting machine, you must also consider the optimization of the control system. Both hardware and software are an essential part of the paper slitting machine.

A slitting machine is a type of basic flexible packaging equipment that consists of unwinding, slit cutting, and rewinding operations to complete the unique procedure. It is used for slitting larger rolls of materials into smaller ones.

All types of paper, such as thermal paper, office copy paper, substration paper, craft paper, white paper, and so on, have a tight link with the high speed paper slitting rewinding machine.

Many types of paper parent web or paper jumbo roll can be converted to small rolls for future usage with a paper slitting rewinding machine.

Working

For slitting, the slitting rewinding machine uses a circular disc knife or a straight razor blade.

After unwinding, the mother large rolls are un-wind, and a single layer of paper material is entered through the slitting cutting station.

Here, it is sliced into pre-set data and then re-wind to various lengths and widths.

A paper slitting machine is a slitting machine that is used to slit paper or paper cardboard in a professional setting.

Special slitting machines, such as toilet paper slitting machines and paper tape slitting machines, are available.

However, the paper slitting rewinding machine is the most common on the market.

Jota only uses coated paper and white cardboard with grey paper cardboard, which is more widespread in the printing and packaging industry, due to the vast choice of paper mother rolls.

Rollers

The rollers used in the high speed paper slitting rewinding machine are all steel rollers with a diameter greater than D250mm.

These rollers have an excellent wrapping capability, so stuck paper can be slit using this approach.

JOTA’s Mechanical engineers cleverly built each driving roller to produce a proper angle to protect the stretchability of the paper reels.

The D450mm bottom roller binds the paper cardboard well after it enters the rewinding station.

It guarantees that the high-tension requirements are met during high-speed rewinding and slitting.

A minor amount of dust will be formed when the paper cardboard is sliced.

If dust settles on the paper’s surface, it will be taken into the offset press or die cutting machine during the next step.

A pneumatic circular cutter with a dust suction system was carefully tuned by our engineers. It’s made up of a dust suction fan and a closed knife cover.

Dust is automatically collected when cutting, which is both efficient and safe.

Printing and Packaging Industries

Printing and packaging plants, as well as paper mills, use high speed paper slitting rewinding machines.

Heavy-duty single-shaft slitting and rewinding machines are used in paper mills for slitting and rewinding purposes.

Two bottom rollers and one higher pressure roller make up the winding mechanism in the machine. The rewinding single shaft is fixed in it, and the paper enters through the rewinding lower pressure roller.

This maintains the strength tension of the paper surface extremely well. Which allows the machine to run at speeds ranging from 500 to 1000 metres per minute.

The single-shaft slitting machine’s excellent efficiency makes the process of changing rolls a lot easier and saves a lot of time and effort.

Large Paper Mills

Large paper mills commonly use this slitting technology because of its great speed and efficiency.

The breadth of the enormous roll of paper when it comes out of the coating machine is between 3000mm and 5000mm.

Large rolls of paper are fed straight into a wide-width slitting machine, where they are slit or converted into various sizes and then resold.

D1800mm is the largest paper roll diameter.

Printing Industries

You should consider employing high-end level pneumatic round disc knives on your paper slitting machine if you are a large printing plant or paper mill.

Although a knife is expensive, it will enhance quality and speed control significantly.

The pneumatic round disc knife is ideal for adjusting several specifications in paper mills due to its simple adjustment and convenient pneumatic closing.

The most essential feature is that the pneumatic round disc knife has a very small leap during high-speed rotation.

Due to the advantages of the structure, the maximum cutting speed can reach 1000m/min.

The majority of the market accepts it due to its exceptional performance.

Moreover, these machines are used in the banks, ATM, hospitals, and POS.

How Does a Paper Slitter Rewinder Machine work?

The working mechanism of a slitter rewinder machine is not as complicated as you may think. We have designed our paper rewinders to be as simple as possible. We have also factored in efficiency and ease of use.

Paper rewinder slitters have three main components that include the unwind, the slitter, and the rewind. The three parts work simply. Three processes occur when you feed the jumbo paper roll into the paper slitter. First, the paper will be unwound. Secondly, it will be slit into different widths according to your slitter rewinder machine setting. And lastly, it will be rewound according to the cut widths.

Unwinder

The unwinding sections of a paper slitter work by unwinding the jumbo paper roll. This is done by feeding the jumbo paper roll into the unwinder drum. We manufacture both the two-drum winder slitter machines and four drum rewinder paper slitter machines. The drum rewinders are equipped with a hydraulic shaftless jumbo roll loading system.

Our paper slitter rewinder machines have a significant loading capacity. You can get paper rewinders with a capacity of more than 2500mm in width. The jumbo paper roll diameter capacity 1500mm is.

The paper rewinder slitter is also equipped with a guiding roller. The guiding roller ensures that the jumbo paper roll enters the slitter at the set angle. It also works to ensure that there is no deviation in the slitting process. The guiding roller also minimizes paper wastage and the paper slitter downtime ratio.

Our paper slitter rewinder machines automatically draw web paper out into the longitudinal slit section. This means that you will not have to put the web through the bottom of two drums. This will save you time, labor, and shorten the debugging time. Our paper rewinder slitters are fully automated to ensure efficiency.

The Slitter

The slitter section of a paper slitter rewinder machine is the most important section of the machine. This section of a splitter machine impacts the quality of your paper processing. This is where the actual separation of the web into smaller slits occurs. The jumbo paper roll is passed through a series of rollers through the slitter head. The slitter head is a mage of a series of rotating round disc cutters. The round disc cutters are usually adjusted electronically to required widths depending on the type of paper being cut. The pneumatic cutter can also be interchanged depending on the type of paper being cut.

Before the web of paper reaches the splitter head, it is spread to straighten it. Straightening ensures ensure that you get good quality cuts.

The slitter round disc cutters are of various types and use. They can be set to cut the jumbo paper rolls into various widths and trim them. Round slitter disc cutters are also used in cutting the back and front edges of the paper roll.

Most of our paper slitter rewinder machines have several configurations of slitter blades. Our paper slitters can have 4 to more than 20 blades depending on your specification.

We ensure that we equip our paper rewinders with knives with minimum cutting resistance. The wear resistance is at the maximum. The round disc cutters installed on our paper slitters can also reach micron levels. The pneumatic cutters consist of a crossbeam, cylinder, knife holder, round knife, and linear guide.

You must ensure that your disc cutters are set accordingly. Factor in the size, shape, and thickness of the paper. The slitting method can be either tangent slitting or wrap slitting. The type of slipping depends on the path the web follows and where the knives are located. Ensure that the web tension is maintained throughout for clean and quality cuts.

The slitter section of your paper slitter must be located in an area with sufficient space for operation. You can either install it with an overhead configuration or in the basement. The installation is flexible because you can have spreader rolls before or after the slitters.

The Rewinder

The rewinder section of a slitter machine is also very important in a slitter rewinder machine. Our paper slitting machine is equipped with two drum surface slitter rewinders in the rewinding section. The drum surface slitter rewinders serve to support and drive the rewinding shaft and reduce roll vibration.

You should note that there is a differentiation between two drum winders and single drum winders. Most of the available slitter machines have a two-drum winder. The two-drum winders are preferred because they wind the rolls on a single axis.

Some of the common paper you can rewind on a two-drum winder include:

  • Fine paper
  • Tissues
  • Newsprint
  • Board grades
  • Paper towels.
  • Receipt paper

We have also fitted a lay-on roller that lays on the web of paper that has been slit. The lay-on paper ensures stability in the rewinding effect. After the slitted web is rewound, it then joins the finished roll discharging.

Finished rolls are held by the rewinding shaft that is then ejected out by the ejecting unit. It is then lowered down by the lowering platform. The finished rolls are then rolled out of the paper slitter machine.

To have high-quality slitted paper, ensure that:

  • The parent rolls are free from defects and folds.
  • You should also ensure that the slitters or blades are well set to your standards and specifications.
  • Ensure the parent rolls have straight-edged end faces.
  • The rewinding hardness should be slightly decreasing from inside to outside or as constant as possible.
  • Ensure that the jumbo paper and the slitted web of paper show a good winding structure.

What are the major sections of a paper slitting machine?

At Jota machinery, we ensure the highest standards in the manufacturing of the paper slitter machines. Our paper slitting machines come equipped with various features that are salient to its functioning. Paper slitting machines have three distinct sections that are important components in any paper slitting machine. four components include:

The Unwinder sections

The unwinding section of a paper slitting machine is where the jumbo paper roll is winded. The reason of the unwinding is to ready the paper roll for slitting. Before any operation in these sections, there are several items that you are supposed to check. Some of the things you must check are as follow:

  • First, check the controls and all the switches of the machine. Ensure that you make a test run to check that all the components are working. If the paper slitting machine has a touch screen, ensure it responds to commands.
  • Make a 360-degree check on your paper slitting machine to ensure every component is intact. This is vital in ensuring that the machine works properly. It also serves to avoid accidents. Be sure to remove any unwanted items or tools on the paper slitter.
  • You must check the pneumatic cutters and adjust them accordingly. These must be positioned in a way that corresponds to the angle and size of the jumbo paper role. The round dis cutters should also corresponds to the final paper sizes.
  • Ensure that the tension of the parent roll is adjusted accordingly. The parent roll should have the required tension to avowing poor slitting. Poorly slitted paper leads to poor quality of the slitted paper.
  • Ensure that the round disc cutters sharpness is ideal for the material to be slitted. Blunt round disc cutters will damage your paper rolls.
  • Check the whole paper slitter machine line to ensure there is no paper left from previous tasks. Set the paper roll slitter machines to your exact specifications.

After going through the above steps, you can then insert the jumbo paper roll. This is achieved by feeding the jumbo paper roll into the paper slitting machine. The unwinding stage consists of an unwind stand onto which the parent roll of paper is loaded and secured. The unwinding section is equipped with spreading rollers. These rollers hold the paper roll into place. The paper roll is held into place by the unwind stand. The unwind stand allows the paper roll to rotate by holding it into its central axis.

Our paper roll slitters have clamping mechanisms to hold the jumbo paper roll into place. We also have paper slitter rewinder machines equipped with shafts on both ends of the roll. These shafts clamp the parent roll into place directing it into the slitter section. Other features in the unwinding section are unwind breaks that ensure that tension is controlled. When tension is too high, the paper roll can break or deform. The unwind breaks are usually manual to give the operator more control. The results of an accurate tension of the paper are quality slitted paper rolls.

The slitter section.

The slitter stage or section of the paper roll slitter I s very important. It largely determines the size, shape, and quality of the paper rolls. Here, the actual separation of the web into multiple smaller slits occurs. This is achieved by setting the blades to the required specifications.

Our thermal paper slitting machines come equipped with multiple round disc cutters. The number of the round disc cutters depends on multiple factors. These factors may include but not limited to:

  • The size of the final rolling paper you require.
  • The texture of the rolling paper being slitted.
  • The designs of the final rolls the customer required.
  • The type of paper or material being slitted with the paper slitter machine.
  • The size of the parent paper roll (jumbo paper roll).
  • The tension of the jumbo paper roll.
  • The speed of the paper slitting machine.

It is important to note that most of our paper slitting machines come with two sets of round disk cutters. The first set is placed at the top of the paper slitter machine. The second set is placed at the bottom to cut the paper roll from the bottom.

The slitter head is the main component in the slitting section. This holds the round disc cutters into place. The round disc cutters can be either rotating discs or static. The type of the pneumatic cutters depends on your specifications.  The series of round disk cutters cut the web of paper into desirable sizes.

Our paper slitting machines round disc cutter also can be configured to be either automatic or manual. Automatic disc cutters are controlled automatically through a central control unit. Manual round disc cutters are usually adjusted by the operator. The operator must adjust the disc cutters by hand whenever they require a certain size of slitted paper roll.

Always ensure that the parent paper is stretched and straightened to ensure good quality cuts.

The rewinder section

At this section, the silted paper roll is rewound into smaller cores on the rewinder stand. This is done to the recommended or desired length. The rewinder machine has different configurations that depend on the desired hardness of the final role. This can be adjusted as you produce different types of paper.

The paper slitting machines that we produce are equipped with rollers which keep the slit sections separately. The rollers are mostly just after the slitter head. This is important especially in avoiding the slitted sections form inter weaving. The interweaving will affect the quality.

In the rewinder zone, the tension must decrease as the rolls get larger so as not to crush cores or break the web. As roll diameters increase, the rewind motor is made to slow down a certain percentage to correspond to the required output.  This is known as the taper tension. Taper tension ensures rolls with natural tension progression that reduces to fewer, or no paper roll defects. Some of the defects that can result from poor tension include:

  • Telescoping rolls
  • Roll blocking
  • Crushed cores
  • Material wrinkles
  • Web stretching
  • Material tears

Some of the ways you can control tension of the web of paper involves three solutions. These include a closed-loop tension controller. You can also use a load cell. Another method is applying a pneumatic break. A magnetic particle break, clutch, or motor drive system can also be utilized. All these solutions will ensure a well-maintained tension.

  • The size of the final paper rolls you want.
  • The width of core in case of core slitting machines
  • The tension of the web needed.
  • The material used for the jumbo roll paper.
  • The location of the round disc cutters.

Sheer slitting method

This type of slitting method involves two round disc cutters. They are usually placed at the bottom and top of the slitter machine. Thee tow disc cutters work to give a cut just like how a pair of scissors works. In slitting machine jargon the top disc cutter is known as the male knife. The bottom one is known as the female or anvil.

Sheer slitting method is preferable when working with relatively thick materials. Thick sheets, cardboards, kraft aper, and laminates are examples of thicker materials. To produce consistent quality cuts, proper tension must be maintained.

Razor slitting

Razor slitting is a type of slitting that utilizes very sharp round disc cutters that are razor like. It is the most suitable slitting methods because it provides very clean cuts. Most of our paper slitter machines are equipped with these type of round disc cutters. They are useful especially in cutting of clean edges.

Some of the most used materials for razor slitting include:

  • Solid Tungsten Carbide for remaking products such as Paper, Polyester, Cellophane, and Nonwovens
  • Solid Ceramic for applied in materials such as Films, Copper Foil, magnetic Tapes, and Nylon LLDPE.
  • Ceramic Coated and TiNI coated applied in Aluminum Foil, Label Stock, PVC, OPP, Stretch Film

Razor slitting is also widely used for paper slitter rewinder machines with unsupported web. An unsupported web set-up requires an entry and exit idler roll. This serves to minimize material fluctuation as it passes through the slitting section. It also stabilizes the web, creating a defined tension allowing for it to be slit properly. At Jota Machinery, we can customize your slitter machine’s web-set up according to your specifications.

Score slitting

Core slitting is a type of slitting whereby a hole is made using paper or other materials. To make cores, you need a specialized core cutting machine. Core slipping machines are used in making a variety of products. Some of the products you can make using a paper tube core making machine include:

  • Paper tube
  • Paper can production
  • Paper tins
  • Tea caddy
  • Food paper cans
  • Wine cans
  • Calendar tubes
  • Tissue paper rolls.
  • Jumbo paper rolls with tubes.
  • Any type of paper tube according to your specifications.

How is precision slitting attained in a Cash register paper roll slitting machine?

If you have been in the paperboard slitting industry, you have severally encountered some conversion terms. Examples of the terms include sheeting, slitting, and rewinding.

What you mostly obtain from organizations is a list showing the following:

  • Listing of maximum roll widths
  • Measurements of the roll
  • Capabilities for slitting, sheeting, and rewinding

However, it is unlikely for you to find an outline of what these services entail. If you are wondering the differences that are there between each service, we have outlined it below:

Sheeting

Sheeting paper refers to conversion of the large paper rolls into sheets of paper. This process uses a paper slitting machine to convert the roll into papers of specific size.

Slitting

At Jota Machinery, slitting entails cutting of long stock roll into thinner segments sing a paper slitter. We can use slitting paper which is as thin as 3/8 inch or wide as 110 inches.

This will be dependent on the specifications that you require.

Rewinding

Once the paper slitting machine has slit the paper, new segments that are thinner are rewound. We can rewind the thinner segments into any size core to the diameter or footage.

In relation to all the aspects of paper conversion, the most important factor is precision. At Jota Machinery, we strive to ensure that every measurement of each customer is perfect.

Every cut on our customer’s orders must always be spot on. In some other cases the rewound rolls which come off a paper slitting machine may be used for other purposes.

Therefore, it is important to make sure that the paper slitting machine winds it perfectly. This will also help in avoidance of wasting time and money or causing a jam.

Use of exact measurements, updated paper slitting machine and technology manufacturing is enhanced. Paper slitting machine manufactures provide product which are very precise.

It is important to establish the specifications, price and capabilities when looking for paper converting services. In addition, ensure that the paper products are very precise. You can contact us at Jota Machinery to find out more about precision slitting and other techniques.

 

What is the importance of web guides and how does it relate to web tension?

A web guide is essential in most unwound stands thus as it keeps the web centered on the machine. Normally, the web guide is fixed to suit a full range of widths for your products.

The adjustable side is attached onto the frame of the paper roll sitter. The web guide requires to be manually set for every product according to the width you want.

Currently, we have several edge sensors in the market which do not need manual adjustment. In the case of different web widths within certain ranges, web guides reduce the changeover time.

You will be required to go to new web widths, and this reduces waste by elimination of operator error in web guide setting.

Web tension is easier and stable to sense before the wind-up position than after the payoff position. This is because the roll for winding possesses less eccentricity as compared to the unwind roll.

The roll on the payoff is larger in diameter as compared to the rewind roll. It is mounted on a bladder mandrel and has been lagged for some period.

It is for this reason that a load cell roll offers more benefits over dancer rolls as a web tension sensor before rewind. This is because there is need for less space and it is less expensive to operate and purchase.

 

Is it possible to have automatic roll removal in paper slitter rewinder operations?

Yes, we can provide automatic roll removal in paper slitter rewinder operations. The paper slitting machine will ensure that the width or length of the master roll is reduced.

Normally, the master roll and wide in a way not suited to your specifications. Therefore, a paper slitter rewinder machine comes in handy to aid in automatic disintegration of the roll.

Jota Machineries offers a wide range of paper slitter rewinder machine to meet each specific requirement. Our paper slitting machines can slit a rewound automatically any material that is flexible.

  • Risks: serious injury to paper slitter operators attempting to split rolls which have run together in production.

Being struck by tools used during reel splitting.

Being struck by a roll when falling from the reel.

  • Controls: Train paper slitting machine operators of the causes of rolls running together so that the frequency of such issues can be avoided.

Use the following measurements when rolls need to be split apart:

  • Return to pulpier.
  • Set aside and slab-off when time is less pressing.
  • Wedge apart

Provide and use appropriate personal protective equipment when manually separating rolls in the paper sitter. Never drop rolls that are bound to split them.

Working on the paper slitting machine when still in motion

  • Wherever possible, the paper slitter must be stopped first before tasks are carried out.
  • All paper slitting machines need to have means of isolating and locking off power in accessible position. Avoid location the power switch for paper slitting machine in a location which is not accessible.
