ABSTRACT:
A resilient stop block for gradually loading the ram of a press for scoring easy open can ends to assure an accurately controlled residual and reduce press noise. The resilient stop block replaces the conventional solid stop block and comprises a metallic member having a longitudinal bore and vertically spaced overlying pairs of diametrically opposed angularly oriented segmental slots extending inwardly through the sides of the block into the bore. The resilient stop block is compressable by the overlying solid stop block as the ram approaches the press bed.
