Abstract

Abstract A doming station for a can body former of the type having a reciprocal ram carrying a metallic can body to and from the doming station for reforming the can body end has a doming die urged to a forward working position by compressible means such that under malfunctioning in which more than one can body is on the can end, the added force will permit the doming die to move rearwardly avoiding damage thereto. An edge forming die ring may be separately similarly mounted telescoping the doming die. A movable frame portion mounts the doming die and is pivotal to and from extending transversely across the ram path of movement. A securing part thereof is movable rectilinearly transversely into a final working position when pivoted into transverse position. In final working position, pressure screws are tightened to exert axial pressure between the movable frame and stationary frame portions to rigidify in the final working position.
