PURPOSE:To suppress the generation of a twist and the remaining of strain in the extrusion molded object extruded from the cap of an auger type extrusion molding machine in the longitudinal direction thereof. CONSTITUTION:An auger screw 5 is built in a main body 4. For example, a cylindrical intermediate barrel 2 is connected to the leading end of the main body 4 and a cap 1 is connected to the leading end of the intermediate barrel 2. A body is extruded from the main body 4 by rotation of the auger screw 5 and passed through the intermediate barrel 2 to be extruded from the cap 1. At this time, the body is molded into a predetermined shape. In order to regulate the rotation of the body extruded from the main body, flat plate-shaped protrusions 6 are provided to the inner wall surface 2a of the intermediate barrel 2 as regulating protrusions. The regulating projections may have a needle shaper or other shape. |
