Abstract
Pressing residue and shell are stripped from a metal-extruder disk having a pair of parallel and flat end faces at least one of which carries pressing residue or shell and an annular outer periphery extending between the end faces and carrying shell. First the disk and a blade are relatively displaced such that the blade sweeps across one of the faces and scrapes any press residue or shell therefrom. Then the disk is rotated about an axis perpendicular to the end faces while a plurality of angularly offset rollers are pressed radially against the shell carried on the outer periphery while the disk is rotating to radially deform the shell and separate it from the outer periphery. The shell separated from the outer periphery is then transported away from the disk.
