Abstract (en)
[origin: EP0065504A2] A cutting device (1), intended particularly for cutting out handles in plastic carrier bags, has a holder (10) connected to a frame (3) and carrying on its underside a driving wheel (16) driven by means of a ball bearing screw (21), and three idle wheels (17). The wheels (16,17) are toothed wheels, and a toothed belt (18) passes over the wheels and carries a cutting knife (19) for cutting out the handles. The holder (10) is vertically movable by means of a pneumatic cylinder (6) from a resting position to a working position for abutment against the carrier bag and with the cutting knife (19) in a starting position. When the cutting knife 19, after passing beyond the end position, has returned to the starting position, the holder (10) can be returned to the resting position for releasing the carrier bag. The cutting knife (19) is movable from the starting position to the end position and back again in that the belt (18) is driven back and forth by means of the driving wheel (16) connected to the ball bearing screw (21).
