Slug retainer for the die assembly of a stamping and forming machine comprises a thin sheet of resilient metal which is on the rear end of the removable portion of the die assembly. Slugs produced by the punch and die are pushed through a slug passageway in the die assembly and through a slug opening in the sheet. The metal sheet has an integral ear which bears agains the endmost slug and which is flexed when the endmost slug is ejected. Slugs are thereby prevented from spilling when the removable portion of the die assembly is removed.

A stamping machine having a punch assembly and a die assembly, the punch assembly and die assembly being in horizontal opposed confronting relationship and being reciprocable relatively towards and away from each other, strip feeding means for intermittently feeding strip material, which is in a vertical plane, along a strip feed path which extends between the punch assembly and the die assembly, the die assembly having a die opening therein which receives a punch carried by the punch assembly whereby, during each operating cycle, a slug is punched from the material and is pushed by the punch into the die opening, the die assembly having a slug receiving cavity therein which is spaced from the die opening and having a slug passageway extending from the die opening to a slug outlet which communicates with the slug receiving cavity so that slugs produced during continuous operation of the machine are stacked in, and pushed through, the passageway and into the slug receiving cavity, the die assembly comprising a removable portion and a fixed portion, the die opening and the passageway being in the removable portion, the slug receiving cavity being in the fixed portion, the stamping machine being characterized in that: a primary slug retaining means is provided at the slug outlet for preventing spillage of slugs from the slug passageway, the primary retaining means being on the removable portion of the die assembly adjacent to the slug outlet and extending partially across the slug outlet, the primary retaining means being resiliently deformable during movement of the stack of slugs through the slug passageway thereby to permit the endmost slug of the stack to pass from the slug outlet, the primary retaining means being effective to retain the endmost slug in the stack during periods of non-operation of the machine whereby, the removable portion of the die assembly can be removed from the machine without spillage of slugs.
