Apparatus for extruding rubber mixtures and/or plastics

摘要

The invention relates to an apparatus for extruding rubber mixtures and/or plastics from an extruder head which is shared by a plurality of extruders, is firmly connected to one extruder and is connected to at least one further, displaceably set-up extruder by means of a connection pipe mounted in an articulated manner in ball joints. It is the object of the invention to provide a possible way of aligning the connected extruder and the connecting pipe connecting it to the extruder head exactly in the axis of the feedpipe in the extruder head. The invention consists in that the extruder head and/or the articulatively connected extruder is provided with a firmly attached pipe piece or a ring which concentrically surrounds the connection pipe at a distance from it and in its unswivelled position, and that on the connection pipe there is arranged a slide valve, provided at least towards one side with a uniformly tapering surface.
