Efficient slitting
Technology
After lamination edges always need to be removed and if multiple print lines are printed side-by-side, then the material on the reel must be slit. This means that besides the printing and laminator machine, a slitter-rewinder is always required. As a unique solution in the world we equipped all of our laminator machines with slitter unit and this way offering to our Customers two complete machines with one investment with better utilization and faster return on investment. In that case when the rolls need to be cut more than four web path, this job can be performed with a separate slitter-rewinder most efficiently due to the built-in friction shafts and the side removal of the reel.

Reel slitting
The pneumatic actuation knife holder is suitable for both rotary knives and industrial blades. Replacing the lower and upper knives is easy. The cutting size can be set with an accuracy of 1 mm simply manually or automatically. In basic configuration the machine is equipped with edge exhaust, which are use when slitting the edges of materials. Also, a laser marker is part of the slitting unit. When turned on, a laser beam marks the slitting line on the material and the position of the paper tubes on both friction shafts, so the positioning of the paper tubes is easily done in case slitting. The material-clamping vacuum table allows the print to be precisely adjusted at gluing after roll change. Optional automatic finished roll pushing and stacking on pallet, automatic cutting size (rotary knife) adjustment and print inspection functions are also available.
Structure
The compact design machine requires 10 m2 of space, installation is simple and the operation requires only electric power supply and compressed air supply. The machine is built on a robust cast iron framework. Its stability is ensured by robust spacers.
Speed
The mechanical speed of the machine is equal to its highest slitting speed of 600 m/min.
Width
One of the main features of the slitter-rewinder is the slitting width. According to customer feedback raw material is available without extra charge of cutting mainly between 1200-1300 mm. The machine is designed not only to slit the reel and edge but also to prepare raw material for printing thus most of our customers order slitter-rewinder machines with 1300 mm maximum material width. As a manufacturer of unique machines as well, for special request we produce machines with maximum slitting width between 500-1500 mm.
Winding
The purpose of the winding system is unwinding and rewinding of the substrate. Both winding unit is controlled by separate servo motors and top-quality servo inverters with built-in pulling force dynamometers, which maintain a constant positive pulling force of 5 Newton, with minimal energy, regardless of actual track speed and reel diameter. The desired positive pulling force can be set on a color touch screen terminal. The unwinder are suitable for bi-directional winding while the substrate is kept stable and secured by conical clamps or pneumatic expanding shaft. In case of expansion shaft, a reel lifting table can also be ordered. Edge control equipped with motorized adjustable ultrasonic sensors is installed back of the unwinding roller to ensure uniform lateral positioning of the substrate, which is completed with a print detection camera which can control the print regardless whether or not the print is continuous or dashed and regardless of its width. Significance of this control becomes apparent when edge removal needs to be adjusted to the print. The rewinder has built-in friction shafts with side roll unloading, pneumatically operated pressure rollers.
Online remote
Thanks to the VPN connection, we can connect to our machines in case of of any assistance or error, and can start providing assistance, support or troubleshooting directly with our engineers free of charge. Software updates can also be installed via the remote monitoring system from our headquarters in Lengyeltóti.
