<p>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.</p> |
