Abstract
Extruder comprises a shearing tool (26) having an arm (27) and arranged directly in front of a nozzle plate (24) at the screw tip (9). A shearing gap (30) is formed between the shearing tool and the nozzle plate. Preferred Features: The arm has a surface running toward a hub. The arm is arranged with the downstream end of the screw bar (22b, 22c) of the screw tip. Nozzle holes (25) are arranged on an annular surface.
