Functional Description
A measuring wheel rides on the material and determines the position and
velocity of the material.
The crosscutter is placed at the end of a (corrugated) paper production
line, for example. The end product of such machines are stacked sheets
with various lengths. A wide range of formats must be covered which
requires running the cut cylinder in electronic cam mode.
Fig. 1-25: Process: Cut-off single sheets from blank material
The basic issue in such applications is a job change without stopping the
machine. The next figure shows an example for a job change from format
A to a shorter format B.
