Conversion of a knife unit from circular knives to pinch knifes
In contrast to the continuous shear cut with upper and lower knifes, only one cutting edge is in use with the crush knife. It is pressed with high pressure by the material to be cut onto a counter shaft.
The main advantage of pinch knifes is the very short setup time. You can change over from one job to the next very quickly, thus reducing downtimes.
Setting up a spherical friction shaft
Friction shafts consist of individual segments (friction rings) which can be twisted relative to each other. This allows rolls with different diameters, for example, to be wound on the same shaft, although they rotate at different speeds.
Friction linings inside the shaft are pressed against the friction rings by compressed air. The transmitted torque can be adjusted by varying the air pressure.
In order to achieve a uniform winding of the rolls, it is recommended to keep an advance of the friction shaft of up to 5% compared to the web speed.
Die cutting and cutting with two die cutting units
In this rotary die cutting machine, two die cutting tool holders (die cutting heads, die cutting modules) are arranged one behind the other. In this way, multiple blanks can be punched very close together in the first punching unit, weeded immediately afterwards and cut exactly between the blanks with the second rotary punching head. Even if the distance between the die-cut parts is less than 1 mm, single rolls can be cut in this way. The EASYline RII-320 thus comes very close to achieving the goal of maximum possible area utilization, and waste (die-cutting waste) is minimized as far as possible.

Since our diecutting machines are modular, add-ons such as further winders and unwinders, a greater distance between the diecutting units and, for example, laminating stations can be added to the basic setup of the line.
