Abstract

The optical system monitoring progress (16, 17) determines the actual spatial position of the sheet from a guide (13). This position is compared with the ideal, using pattern recognition. From the comparison, the evaluation unit (18) controls a unit moderating the course (14) of the sheet through the machine.
