JT-SLT-2500C High-Speed Kraft Paper Two Drum Slitting Rewinding Machine
One of we Jota’s Chile clients purchased 2 sets JT-SLT-2500C high-speed kraft paper two drum slitting rewinding machine, and they sent back a feedback video to us.
In order to assist this client successfully running these 2 machines, we Jota’s engineers flew from China to Chile and spent a month in Chile.
From ground base construction to finished roll discharging, we Jota’s engineers guided customers carefully, until the customer side’s engineers fully grasp.
This Chile client was quite satisfied with we Jota’s attentive service during we Jota engineers’ 1-month stay in Chile.
Customer satisfaction is always we Jota’s relentless pursuit. Before this Chile client purchasing JT-SLT-2500C two drum slitter rewinder machines from us, they have bought 1 set Jota old version 2100mm width kraft paper slitting machine.
Old Version 2100mm Width Kraft Paper Slitting Machine
This old version kraft paper slitter rewinder served many years for Chile client, Chile client’s business got much bigger and better. They grew up to Chile’s top paper converting supplier. Their factory is filled with many machines, include some European ones.
Their factory converts kraft paper, whiteboard paper, specialty paper, photocopy paper, etc.
Because the business of this Chilean customer continues to expand, they want to expand production capacity, so they chose to purchase 2500mm width kraft paper roll slitting machine from us.
JT-SLT-2500C Two Drum Slitter Winder Machine
With 2 sets JT-SLT-2500C two drum slitting and rewinding machine, Chile client’s production capacity could be definitely upgraded to a higher level. Because JT-SLT-2500C’s initial design has many beneficial features.
For JT-SLT-2500C two drum craft paper winder machine, it includes several important sections, such as unwinding, web guiding and threading, longitudinal slit, rewinding, finished roll ejecting and discharging, control system, etc.
Regarding the unwinding section, JT-SLT-2500C two drum winder equips with hydraulic shaftless jumbo roll loading system.
With such system, Chile client’s operator doesn’t need to put unwinding shaft through kraft paper jumbo roll, operation is much simpler, jumbo roll loading time could be effectively saved.
What’s more, hydraulic system’s loading capacity is stronger. That means, JT-SLT-2500C roll cutter slitter is able to load and bear 2500mm width, 1500mm diameter kraft paper or whiteboard paper jumbo roll.
With respect to web guiding and threading section, web guiding roller ensures the parent web enters the slitting device at a constant angle, avoids material deviation, decrease material waste and machine downtime ratio;
Web threading device automatically drawing web paper out between two drums, then Chile client’s operator doesn’t need to lie on the ground, then put web through the bottom of two drums, operator’s labor and time are saved, this part’s debugging time will also be shortened.
With regard to longitudinal slit section, it adopts shear cutting.
The upper pneumatic circular knife unit consists of crossbeam, cylinder, knife holder, round knife, linear guide, it is imported from Taiwan, cutting resistance is minimum and the wear resistance is maximum, slitting accuracy could reach the micron level.
And lower round knife unit is composed of knife shaft, round knife, bearing base, inverter motor.
For JT-SLT-2500C two drum surface slitter rewinder’s rewinding section, as the machine equips with two drums, these two drums not only support and drive rewinding shaft rotating but also reduce roll vibration.
Besides, there is a lay-on roller riding on rewinding roll during machine running, ensures the final rewinding effect is great.
After rewinding finished, it comes to finished roll discharging. Rewinding shaft with finished rolls will be ejected out by ejecting unit first, rolls down to lowering platform, then lowering platform turns down a certain angle, these finished rolls are unloaded to the ground.
Of course, we couldn’t ignore the most important control system, it is the brain of Chile client’s JT-SL-2500C two drum high speed slitting machine.
This Chile client bought 2 sets JT-SLT-2500C from we Jota, the first one is dashboard panel control without touch screen. The customer still think it is more convenient to control with touch screen, so we Jota customized touch screen control as Chile client’s request.
Now, Chile client’s 2nd JT-SLT-2500C rotary shear slitting rewinding machine is quite convenient for use with touch screen.
So, if you also want to customize your own dreamy jumbo roll kraft paper slitting rewinding machine, we Jota is definitely worthy of your trust.
You could also enjoy the same service as Chile client. What you need to do now, is just simply submit your request to us, we are always ready to offer one-on-one service to you.
