Cutting and Rewinding Innovation

With the improvement of the manufacturing level in various industrial fields, higher and higher requirements have been put forward for slitting and rewinding technology. Thus, in order to meet the needs of different customers, there has been a series of innovations in the field of slitting and rewinding.


Parkland increases production capacity Parkland's new Series III dual center slitter rewinder further enhances the company's existing SM150 series production capacity. The first new machine has been delivered to a European customer. Its maximum slitting web width is 2,050 mm, maximum rewinding diameter is 800 mm, and operating speed can reach 600 m/min.
By adopting a mechanized processing system at the unwinding and rewinding end of the machine, this new model can improve productivity and reduce the burden on operators. An integrated shaftless roll stand uses several hydraulic pick-up arms with progressive chucks to locate and lift the roll to be processed. These pick-up arms can be moved individually or together so that center or offset rewind operations can be performed.
The fully redesigned pendant operator panel allows the operator to control settings from different working positions. When changing the slit width, the laser coil core positioning system saves time and ensures accurate alignment. By using a multi-tool station on the bottom shaft, it is also possible to further save time. It is also possible to provide a wedge-shaped top tool holder with a blade insert and a push-button pneumatic tool mounting device.
The reels are also cantilevered. When the machine is in operation, they will be trapped in a chamber inside a rotating side door under pneumatic action. To remove the finished roll, an unloader will engage the shaft end, and the side door will swing open. By means of the automatic ejection mechanism, the reel will slide from the shaft to the corresponding arm of the unloading car and finally be transported by the unloading car.
According to the latest health and safety requirements, the protection of operators has also been improved. When someone approaches the boundary of the safe working area, a two-stage laser detector mounted on the rewind side will give an alarm. If the person continues to approach, the detector will automatically shut down the machine.


Optional automatic turret configuration
The automated turret slitter made by DCM Usimeca provides an automated turret sequence process, but the operator still plays a major role in removing the finished coil and replacing the new coil core. This helps reduce the cost of the machine's fixed assets.
Versatility is another factor. This machine can be equipped with a single-axis turret or a twin-axis turret with a machining speed of up to 600 m/min. An integrated shaftless or shaftless roll-to-place reel is also available, and its operating platform is well-designed for easy replacement or installation of automatic tooling systems. DCM's own Pilot system is responsible for performing fully automatic tension control tasks.
This model uses an AC drive motor with PLC control, a modem interface, and a display interface with a memory control function.

Newest Vectra products greatly increase the output of compact label webs <br> The new member of the Vectra series supplied by AB Graphic International is a four-axis turret rewinder for high-speed production of small-format label webs .
This 330mm wide turret rewinder can produce rolls with a diameter of 30 to 150mm. The processing speed depends on the diameter of the mandrel used. If a mandrel with a diameter of 30-50 mm is used, the speed can reach 150 m/min; with a mandrel with a diameter of 12-25 mm, the speed can reach 90 m/min.

In addition, the processed coils can be automatically sent out.


Atlas is FILMtech's favorite
When the fast-growing US metallized film manufacturer FILMtech decided to enhance its slitting capability, it did not hesitate to find its first machine supplier, Atlas Converting Equipment.
“We used the Atlas CW800 film slitting machine to process a large amount of materials, including BOPP, CPP, LDPE, nylon, polyester and PVC, etc. It has been continuously running.” Operation manager Keith Stansberry explained, “This machine is so So good that when we bought the second unit, we did not hesitate to continue to choose Atlas. The second machine will be installed this summer. It is very flexible and versatile, can run without interruption, 24 hours a day, every week. In seven days, without any reliability problems, we can produce high-quality coils at a speed of up to 800m/min. The longer it takes, the higher our output."
FILMtech is located in Bean Station, Tennessee, with an area of ​​4,250 square meters, where there are two vacuum metallization machines, including a universal EHF metallizer installed last year. The company can process coils up to 3,300 mm in width, up to 1,000 mm in diameter, and between 10 and 50 microns thick. The current output has exceeded 5,000 tons/year. The processed products include metallized films and films with transparent barrier coatings. Some have also undergone surface treatment as required. There are also heat sealing films and optical films. Density ranges from 0.2 to 3.0+.
Stan Braycotton, product manager at Atlas Slitter Rewinders, explained: “The first CW800 slitter rewinder installed at FILMtech in June 2004 has four rewinding stations with a processable web width of up to 3,300mm. The new machines that will be installed this year are also similar configurations.
Among Atlas's products, the CW800 is the most successful secondary film slitting machine. Currently, there are more than 50 CW800s operating on metallization, CPP and BOPP film production lines all over the world.


No fault rewinding <br> To ensure perfect coiling of blown film products, W&H has developed the Filmatic TX turret reel. The machine's features include minimal contact pressure, no adhesive at the start of a new coil, coil center and gap winding at the beginning of the coil, and the ability to rotate in reverse.
When operating with W&H's Varex blown film line, the TX coiler can process films with a width of 1,600 to 3,600 mm at speeds up to 200 m/min, and when it is upstream of a Filmex cast film system, the take-up speed can reach 450 m. /min. The largest coil diameter is 1000mm. Each take-up unit is equipped with a Windows-based touch screen that makes the coiler easier to operate.
For multi-coil production, the coiler can be equipped with heated tools, extension rollers and slitter drum traction. The heated tool requires only minimal cutting pressure, which reduces the blade construction time and increases the service life of the blade. Roller traction is said to ensure web tension and achieve trouble-free slitting.
A reel lifting and extraction system can help with handling operations and benefit the space available. The Filmatic TX and take-up unit can be mounted back to back or face to face.

Sapphire cutting machine capable of cutting copper
Ashe Converting Equipment claims that other manufacturers rarely match the Sapphire slitter it manufactures to process a copper material. Not only is the material itself challenging, the machine itself is also configured to operate in cleanroom conditions.
In order to achieve this important task, Sapphire uses a tangential rotary shear cutting method and a closed loop tension control. Ashe's chief engineer, Keith Fordham, said that tangential slitting is the most practical method, and that stiff materials can be deflected away from the tool without any damage. In the tangential slitting system, the web and the lower slitting knife are only in contact at the tangent point. The top tool plunge system is much better than a wrapped system, but the tool is fixed
