ABSTRACT:
A press for the preparation of raw plastic material blanks is described. It has a feed device connected to a rotor housing in which a circular rotor is eccentrically supported for the generation of pressure and the transport of the material. Rotor housing and rotor form a tapering channel. The circular rotor has at least one axially extending material transport ridge forcibly guided along a guide rail located in the rotor housing. At its smaller end the tapering channel forms an extrusion gap which opens into an outlet opening for the plastic material, to which a nozzle is attached.
