Abstract

A screw extruder for the processing of a strip of rubber or plastic has in the region of the feed throat a feed roll arranged parallel with respect to the extruder screw. In order to improve the feed behaviour of the screw extruder and to improve the extrusion quality, a rotatable supply roller (21), lying transversely with respect to the extruder axis, is arranged above the feed throat (13). The supply roller (21) is mounted movable in the vertical direction and is wrapped around part of the circumferential surface on the discharge side by the material strip (37) supplied approximately from above. <IMAGE>
