How Does the Multifunction Slitter Rewinder Machine Work?

A multifunction slitter rewinder machine is a machine used to cut large rolls of material into narrower rolls.

To understand how a multifunction slitter rewinder machine works, it is important to learn it in sections.

Slitter rewinders perform a type of shearing that cuts large rolls of material into several smaller rolls.

A slitter rewinder unwinds the material, runs it through the machine to be cut, and rewinds the material on one or more shafts to form narrower rolls.

The three main parts of the working of a slitting rewinding machine are the unwind, the slitting section, and the rewind.


The unwind is normally braked to maintain accurate tension in the material.

Some machines have a driven unwind which reduces the effect of inertia.

Inertia is reduced when starting to unwind heavy rolls or when the material is very tension sensitive.

unwinding stand

The unwinding stage consists of an unwind stand onto which the parent roll of paper is loaded and secured.

The stand holds the roll about its central axis and allows it to rotate.

The roll is held either by inserting two chucks each with mechanical gripping elements on both ends of the roll which expand to grab it.

It also works by clamping the two exposed ends of a shaft which runs along the whole length of the roll’s core on bearings on the back stand.

When heavy rolls are first unwound, they have a lot of momentum, which can cause the paper to tear or deform materials that are sensitive to pressure.

This doesn’t happen because driven unwinds can be stopped when needed. During the process, the brakes help keep the material at the right tension.

Our paper heavy-duty slitting rewinding machine has clamping mechanisms to hold the jumbo paper roll into place.

We also have slitting rewinding machines equipped with shafts on both ends of the roll.

These shafts clamp the parent roll into place directing it into the slitter section.

Slitting Section

The slitter stage or section of the multi-function stretch slitter rewinder machine is 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.

The slitting stage is where the actual separation of the web into multiple smaller slits occurs.

From the winding stage, the unwound continuous web of paper is passed through a series of spreading rollers and through the slitter head.

1600F round slitting knife

The slitter head is made up of a series of rotating round disc cutters or razors and it does the cutting of the web.

The desired slit widths are set manually or automatically depending on the type of machine being used by varying the locations of the knives on the slitter head.

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 pneumatic cutters depends on your specifications.

The series of round disk cutters cut the web of paper into desirable sizes.

The cutting method that our multi-function stretch slitter rewinder machine apply is shear cutting.

Here, a bottom-placed round disc cutters work with an upper round disc cutter.

They work in tandem and produce a scissor-like cut. It produces very clean cuts of very high quality.

It is important that you ensure that the round disc cutters are always well set and aligned.

This is to avoid having uneven cuts. Blunt round disc cutters will also lead to uneven edges.


Rewind slitting involves rewinding the material through several round disc cutters to form narrower rolls of materials.

The slits are rewound onto smaller cores on the rewind stand to the desired footage or diameter.

prepreg cutting

This occurs from the slitter head. Various factors determine the type of winder to be used under a given condition.

The rollers which are after the slitter head keep the slit sections separate.

This is as they enter the winding and prevent the sheet from weaving back and forth. This occurs between adjacent rolls in the roll set.

What Are the Winder Procedures, Operations, And Safety of a Slitting Rewinding Machine?

The winder procedures, operations, and safety of a slitting rewinding machine serve as guides.

The guide is on how to operate the slitting rewinding machine.

1300F slitter rewinder

It is worth noting that different slitting rewinding machines have different procedures on operation and safety.

Most of the slitting rewinding machines in the market are controlled by the machine-man-machine interface.

Prestart Procedure

Before the start of operation of the multi-purpose slitter rewinder, it is important to carry out a pre-startup procedure. The prestart-up procedure includes;

  • Checking and making sure that the slitting rewinding machine area is clear of any debris.
  • Beware of incomplete installation of equipment and any fasteners or loose parts lying around.
  • You should check the shutdown list of your multifunction laminating slitting machine. some of the items to check to include:
  • Electrical work required
  • Maintenance work is required.
  • Any unusual items that may have been shut down or disabled.
  • Carry out a 360-degree inspection of your multifunction laminating slitting machine. This is to make sure that the multifunction laminating slitting machine framework is free from tools and equipment not necessary. It is also important in noting any underlying defects.
  • The next procedure is to clear all the foreign materials away from your slitting rewinding machine.
  • Use the collect instruments, and that all the indicating instruments are in working order.
  • Ensure that all the safety guards are in place and that the machine/man interface (MMI) power is ON.

Roll line up

It is also important to check the roll line up for your multi-function stretch slitter rewinder machine.

It is an easy procedure that requires you to indicate the slitting rewinding machine production.

It is a comprehensive checklist on the working of the slitters.

Mechanisms such as the slitter widths, basis weight, set diameter, with of the roll to be cut, and a number of rolls order are some of the items to check in the roll line up.

Specified core size and related information trim average and number of rolls to be cut within the set at the specified width should also be checked. Check to make sure the specified cores (diameter and length) are on hand at the winder.

Unwind Stand

Check to make sure the unwind stand is centered before mounting a new jumbo roll on the slitting rewinding machine unwind stand.

Core Ejection

The cores can be injected both automatically and manually.

New cores must be introduced to the winder using the core feeder.

The cores will automatically be applied with glue during the feeding process.

The reel ejector must be in the return position to take the cores from the feeder and place them, between the winding drums.


Always stop the multifunction laminating slitting machine a few inches before the set diameter.

The amount of diameter added to a set after the STOP button is pressed will vary depending on the caliper of the paper.

The speed of the winder will also determine the amount of diameter added to a set.

When the automatic STOP CONTROL selector switch is activated, the winder will automatically shut down when the desired roll diameter is achieved.

Before shutting down the winder system, ALWAYS check to make sure no one is working on the winder.

Also check that all operating devices are in their home positions.


What Is the Difference Between a Single Drum, Two Drum, And Duplex Winders in Multipurpose Slitter Rewinder?

Both the single drum, two drum, and duplex winders are types of slitting machine winders.

Businesses in the paper mill industry often use enormous spools of material in their day-to-day work. But how does an enormous amount of material get onto a spool in the first place?

An answer is a winding machine, which can quickly jumbo paper roll onto an industrial-size spool as needed.

To understand the different types of winders, it is important to be knowledgeable of the multipurpose slitter rewinder features. The features include:

  • Web break detection: Multipurpose slitter rewinder include sensors that monitor the material being rewinder. Many of these sensors work by sending a beam of light toward the material and detecting whether the light is reflected.
  • Automatic splice initiation: Automatic splicing features are used to create clean cuts with no overlap. In general, automatic splicing features are used to enhance productivity, control quality, and reduce waste.
  • Roll changing: Roll-changing features allow users to set maximum diameters for spooling. Once that maximum diameter has been reached, the roll-changing feature swaps out the full spool for a new one.
  • Actuated knife cut-off: Actuated knife cut-off triggers a blade to cleanly cut the end of the material once the web has reached its maximum diameter. Quality round disc cutters create clean, precise cuts.

Duplex Slitter rewinders

These type of rewinders are used where certain substrates cannot be wound on a single shaft.

These materials, such as most films, will interweave or create other problems unless the slit cuts are alternated up and down on two rewind shafts.

Often each slit cut is affixed to the rewind shaft through a series of spacers which act as clutches, allowing each roll to wind correctly.

These winders can use score slitting, shear slitting, or razor slitting methods.


Two Drum Slitter Rewinder

Two drum surface slitters are commonly used to slit and rewind paper and board products.

They wind the material by driving the surface of the roll with the drums while pressure is placed on top of the rewinding roll with a so-called “rider roll”.

The material is typically slit either with a score method or a shear method.

They can slit from very narrow widths, about 2 inches, to very wide widths, more than 150 inches.

And they can slit and rewind a broad range of products from tissue to very dense board.

two drum slitter rewinder

There are many variables involved in choosing the best machine for an application. Feel free to ask for our advice.

Single Drum Slitter Rewinder

Single drum slitter rewinders are used for small rolls of material.

They do not to have to unwind and rewind the substrate.

The jumbo paper roll is placed on a mandrel matching the inside core diameter.

The jumbo paper roll is then rotated while a rotating round disc cutter is inserted into the jumbo paper roll at the appropriate widths.

Other types of slitters rewinders include:

  • Simplex slitters: A Simplex Center Slitter/Rewinder winds a roll on a single shaft in a similar way to a Two Drum Winder. Unlike the two drums, however, the Simplex rewind shaft grabs the core or cores usually by inflating the rewind shaft with air. The air causes an internal bladder to expand thereby pressing buttons or the leaves of the shaft itself inside the core.
  • Continuous winders; Continuous slitters are commonly used for making small diameter logs of material such as gift wrap paper. They are typically fully automatic machines which take a master roll and turn out large quantities of finished rolls requiring only master roll changes.
  • Duplex turret winders: They are ideal for high-speed automated winding of small diameter rolls
  • Traverse winders: Traverse winders have slitting capabilities to convert a single wide web to several smaller ones. After being slit, the narrower webs are distributed across the width of the cores, or “spools”, onto which they are being rewound. This yields a high density of material in a finished roll that maintains a reasonable diameter.

It is also worth understanding the different types of slitting lines of slitting rewinding machines. There are two basic types of slitting lines:

  • On pull-through slitting lines, the recoiler provides the power to pull the coil material off the uncoiled reel. This done through the slitter and recoil of the processed strips.
  • In loop-slitting lines, a pit is incorporated into the line. The processed coil strips are looped into the pit which assists in absorbing the strip length differential within the slit coils. The slitter typically provides the power to both uncoil and slit the material, while the recoiler provides the power to rewind the material.

How Can I Optimize the Shear Slitting Process for Multi-Function Stretch Slitter Rewinder Machine?

The slitting process is an important part in any multi-function stretch slitter rewinder machine.

This makes it important to optimize the process to reduce wastages from wrong slitting methods.

Shear slitting is the most versatile and commonly used method to slit flexible web materials.

It is also demanding while requiring close attention to achieve high-quality slitting.

You must ensure that certain variables are controlled to ensure optimization of the slitting process. These variables include;

Round Disc Cutter Sharpness

The multi-function stretch slitter rewinder machine uses a rotary shear process.

The rotary shear process works by slitting materials in the nip between two overlapping round disc cutters.

The hardened round disc cutters create stress in the shear mode sufficient to tear off the web of paper roll.

Razor slitting on the other hand has compressive stress when crush/ score slitting.

The different characteristics of the round disc cutters such as sharpness should not be confused with the grind angle.

The grind angle is also called the cross-sectional profile of the slitting round disc cutters.

razor blade

It is important to ensure that all the disc cutters for your multi-function stretch slitter rewinder machine have sharp edges.

The profile of the round disc cutters can vary widely and still meet the criteria for sharp blades.

Cant Angle

The cant angle is also known as the shear angle. The cant angle assures a closed nip.

Like a pair of scissors, the round disc cutters must be in contact at the nip or cut point to give clean cuts.

The shear angle largely depends on the quality of the material being used on the multi-function stretch slitter rewinder machine.

Certain materials are very sensitive to cant angle settings. Other materials seem to slit well giving clean quality shear cuts.

Elasticity, elongation, and fiber orientation are important factors that you should consider when choosing the optimum cant angle.

Ensure that when you have a low elongation, the cant angle is also low. A high elongation also equals to a high cant angle.


When you increase the tangent point of your multi-function stretch slitter rewinder machine, the upper and lower blades shift the cut point ahead of the tangent point.

This is not recommendable because the blade will tear your web.

The upper round disc cutter strikes the web too soon severing it if it does not get the support of the lower round disc cutters.

Unlike the tangent systems, in wrap systems, the cut point has little effect on slit quality.

Increasing the overlap in both the wrap and tangent systems increases the deflection of the web.

The amount of deflection the web must take to go around the upper blade can decrease the slit edge quality.


Side Force

The sliding force of the multi-function stretch slitter rewinder machine means the amount of force applied from the upper round disc cutter to the lower round disc cutter.

The side force creates friction between the upper round disc cutter and the lower round disc cutter.

This creates a rotational speed of the upper disc cutter creating the nip speed at the cutting point.

Note that a high side force results to the blade wear-causing deflection in the upper disc cutter.

A deflection on the upper disc cutter results in the opening of the nip point.

To mitigate this, the side force should be as light as possible. This is important in maintaining a closed nip and appropriate nip speed.

Nip Velocity vs Web Velocity

In shear slitting, the nip velocity must equal or ideally be faster than the web velocity.

If the nip closes at a speed slower than the web, slit quality reduces.

This leads to dusty, ragged, and distorted paper roll edges.

Any distortion of the web immediately in front of the top slitter is a sign that the slitters are running slower than the web speed.

When using a multi-function stretch slitter rewinder machine with tangent systems, the remedy is increasing the Overspeed to compensate for the speed loss.

On a multi-function stretch slitter rewinder machine with wrap systems, Overspeed is not easily resolved.

This is because you cannot realistically Overspeed enough to compensate for speed differential.

Slitter Geometry

Shear slitting systems can be configured to either tangent or wrap.

Most of the primary winders are configured to tangent slitting.

On the other hand, most of the secondary winders are configured for wrap slitting.

Trim Removal.

As edge trim is removed from the web, the tension across the web is altered.

When the trim material is redirected away from the web path, it leads to the reduction of the slit edge quality.

To promote good edge quality, the supported slit should be on the web site of the edge trim.

The edge trim material should follow the path of the web at the same speed as it leaves the nip point.
