S05-49353M/YO/88 ABSTRACT OF THE DISCLOSURE A method and device are provided for separating trimming losses from a sheet having a plurality of products formed thereon with star-shaped scraps between the products. In one embodiment, the sheet is placed on a sheet supporting plate. The sheet is positioned between a blanking plate and a plurality of pushing rods fixed to a mounting plate. Each of the pushing rods has a piercing pin extending from the free end thereof for penetrating into a corresponding star-shaped scrap. The blanking plate has through holes formed therein which correspond to the pushing rods and star-shaped scraps such that the pushing rod passes through a corresponding through hole. The inner diameter of each through hole is smaller than the outer size or greatest dimension of the star-shaped scrap. When the star-shaped scrap is pushed through the through hole by the pushing rod, it deforms and passes through the through hole. After passing through the through hole, it returns to its original shape and because its outer size is greater than the diameter of the through hole, the star-shaped scrap cannot pass back through the through hole when the pushing rod is drawn back through the through hole. A collection chamber is positioned on the surface of the blanking plate for collecting the star-shaped scraps pushed through the through holes. A vacuum system removes the star-shaped scraps from the collection chamber. Additional embodiments of the method and device are also disclosed.
