Positioning blades on device for cutting material strip, involves detecting distance from one edge to base marker, moving blade to achieve defined distance, disengaging displacement device

摘要

The method involves moving a sensor (15) on a displacement device (8) past the blade (I-III) to be positioned to produce successive edge signals for the edges of the blade, identifying the sensor signals as cutting edge (6) and construction edge (19) signals, detecting the distance from one edge to a base marker, moving the blade to achieve a defined distance then disengaging the displacement device.
