Abstract

For the control of a cutting to the correct design length, particularly to the correct print image, of continuously conveyed webs of material by means of a cutter unit, the web of material is provided with a bar code which is detected in contactless manner at least for measuring speed and acceleration by means of a sensor. Each bar of the bar code is converted into a signal which may be multiplied in a signal conversion unit. By this means a high degree of precision of the cutting position is obtained.
