PUNCHING DEVICE FOR PUNCHING CUT OUT SPECIFIC DESIGN FROM A CONTINUOUS MATERIAL

摘要

A die cutter for die cutting a running web (1) continuously into blanks comprises a blade (3) and an anvil (4) interlocked with each other so that they will contact each other at a point moving from one end of the anvil to the other. Either the feed rolls (6) for the web or the cutting mechanism (3, 4) are electronically controlled so that a length of the web just sufficient for one cutting operation will be supplied to the cutting mechanism while it performs one cycle. The cutting mechanism is kept synchronised with the web speed at least during the period from the start of cutting to its end. IMAGE
