Abstract

1334014 Stripping waste from cut blanks HENRY SIMON Ltd 16 Aug 1972 [20 Aug 1971] 39090/71 Heading B4B An apparatus for stripping waster material a from cut sheets comprises a stripping plate 10 having apertures corresponding with waste to be stripped, a plate having punches 11 each arranged to co-operate with a respective yieldable member 18 adapted to be displaced by the respective punch from an initial position and to return thereto after a delay period following a return movement of the associated punch. The member 18 is in the form of a rod slidably mounted in bearing plates 16, 17 carried by a bracket 15 secured to the plate 10. A suction cup is mounted on the rod and co-operates with a plate 20 fixed to the bracket; a bleed hole 21 is formed in the plate and controlled by a screw 22. In order to prevent noise due to the sudden return of the rod by a spring 25, a collar thereon is arranged to enter a cushioning cylinder 23; alternatively, the cylinder may be replaced by a resilient cushion. In modifications, the axially movable rod may be replaced by a pivoted lever.
