CUTTING

Hauler & Hermann operates 6 state-of-the-art slitting lines for roll-to-roll processing. The machinery is specialized in numerous web-shaped materials such as films, papers, laminates and nonwovens of all kinds in thicknesses from 23 to 2,000 µm. The parent rolls, which weigh up to 1,000 kg and are 1,600 mm wide, are lifted with suitable lifting gear and processed on the slitter rewinders. The materials are cut to the required width using shear cutting. In rotary shear cutting, two circular, overlapping blade disks touch at the sides and shear the continuous material web. This technique enables high cutting speeds to be achieved with a clean cut edge. The minimum cutting width is 4 mm with a tolerance of +/- 0.1 mm. After the cutting unit, the individual strips are fed alternately onto the winding shafts and wound with the appropriate tensile forces. Friction shafts are generally used to ensure optimum winding hardness of the cutting rollers. The processed materials can be wound onto different core diameters. As standard, 1", 3" and 6" cores made of cardboard or plastic are used here.
