  • Patent number: 4974479
    Abstract: System for controlling slugs (10, 10') in a stamping and forming machine has a slug stripper (32) for stripping slugs from the end (13) of the punch (11) and slug supporting bars (78, 80) which support slugs at their edges as they move through a passageway (82). The slug stripper (32) is mounted in the facial surface (18) of the die plate (14) and has an end portion (56) which extends partially over the die opening (44). When the punch (11) descends and punches a notch (8) in the strip material (2), the slug (10, 10') which is produced moves the stripper (32) to a retracted position. When the slug (10, 10') is moved past the end of the slug stripper (32), the slug stripper returns to its normal position so that on the return stroke of the punch the slug will be removed by the end portion (58) of the stripper. The slugs are maintained in a stack in the slug passageway (82) by opposed supporting bars (78, 80) which are resiliently biased against opposite edges of the slugs.
