Abstract

A unit for processing thermoplastic synthetic material comprising a machine housing (1) with a delivery cone (12) in whose feed shaft (14) a driven slider (30) presses synthetic material which is to be processed and which is located on a base plate (7) through a feed inlet (11) of a conveyor tube (6) against a processing drum (3) which is placed perpendicularly in the conveyor tube (6) in relation to the direction of the movement of the slider (30). The slider (30) extends over the entire length of the feed inlet (11) which itself extends over the entire blade supporting section (17) of the processing drum (3). Blades (4) are placed thereon in a helical line and operate in conjunction with a fixed counter blade (5) which is fastened to the opening edge (25) of the feed inlet (11). The blades (4) and the associated screw conveyor (9) convey disintegrated synthetic material in axial direction (20) though the conveyor tube (6) towards an outlet (10), which leads downwards into the screw tube (22) of the extruder screw (8) through which the synthetic material is delivered.
