Device for cutting the lateral edges of paper cuttings

摘要

A device for cutting off lateral edges from paper cuttings to be cut out from a strip of material has a cutter plate mount on a cutter shaft 10. The cutter shaft 10 is of an axial length to match the width of the paper cutting and has a plurality of retaining magnets 15 arranged at the ends thereof, distributed around the circumference. An axial bore 17 communicates with a radial bore 18 and thence to an elongate groove 19. A tongue 20 inserted into the groove has radial bores 21 communicating with grooves 22. Alternate supply of vacuum and pressure to bore 17 allows web material to be attached and detached from the die cutter.
