A separating device for separating the ring-shaped press skin from a composite extrusion disc comprising a press disc and a stripper disc, especially for copper containing alloys and difficult to press metals and alloys, according to which the press disc is spaced from the stripper disc by an annular intermediate space for receiving the press skin. The device includes a separating head with a passage or recess into which project two blocks located opposite to each other. When the combined extrusion disc on its way through the passage passes between these blocks the projecting blocks enter the intermediate space for stripping off the press skin. The distance between the straight guiding means of the blocks is located within a range of from the length of the inner diameter of the combined extrusion disc to a length composed of the length of the inner diameter plus about the thickness of the press skin.

Separating device for removing the press skin from a  combined extrusion

A device for removing the press rest from the front side of a press disc for extruding tubes which has a substantially plane rear surface opposite the front side of the press disc. This disc comprises supporting means for supporting and holding the press disc from which is stripped a press rest. The device also comprises shearing means having a shearing surface which, when the press disc from which the press rest is to be stripped, rests on the supporting means, defines an obtuse angle with the rear surface of the disc. The disc and the shearing means are movable relative toward each other so as to cause the shearing means in response to such movement to strip the press rest off the press disc.
