Adhesive film, hook‑and‑loop tape, and other material lanes are produced on rolls up to 250 centimetres wide and then pre‑cut to a width of about 50 centimetres. The further cutting into strips of 2 to 60 millimetres and subsequent winding on parallel winders takes place on Dietze + Schell plants.
There are various ways of cutting material in industrial application. Scissors have two blades that move towards each other. Pinching separates the material by applying pressure, like a pizza cutter, and a razor cut has a single blade. Cutting systems by Dietze + Schell use all of them for customer‑specific solutions that turn material lanes into narrow ribbons.
The material‑specific blades are assembled outside of the cutting system in a "cartridge" for the respective application and inserted into the machine on demand. This shortens their downtimes during a change.
Servo motors drive the rolls up- and downstream of the cutting unit. The user can precisely adjust the winding speed, and as a result the material tension, in the cutting area - which is particularly relevant for sensitive materials and materials that can easily tear. The motor stops the reels precisely. Additional brakes are not needed.
Dietze + Schell cooperates with subsidiaries to implement entire system solutions: An extruder by SIMA S.r.l. (Italy) and large reels by TRIMA (Czech Republic) are placed upstream, followed by Dietze + Schell cutting units and our parallel winders for rewinding.
