Abstract
An endless screw press for the treatment of thermoplastic synthetic materials, to which the raw material is supplied in the plasticized state, and in which in the transition between the body of the worm and its shaft the worm is sealed to the stationary cylinder case that surrounds it by means of a joint bushing, characterized in that between the body and the shaft of the endless screw there is provided a projection of the body of the endless screw, against whose annular face surface a bushing is kept in contact. of the gasket supported on the cylinder secured against rotation and traversed by the shaft of the endless screw, by means of a pressure medium, which bears against a stationary part of the machine, the front surface (s) being armed (s) (is) annular (s) of the projection of the body of the worm and/or of the joint cap with wear-resistant material.
