出部構造を提供することを目的とする。FIG. 3 is an enlarged view of the nipple portion of the rotary wheel type extruder. The core wire 10 passes through the core wire introducing portion 13 of the nipple 9 and enters the collecting chamber 8. The clearance between the core wire 10 and the core wire introduction portion 13 of the nipple 9 is narrowed in order to prevent uneven thickness of the obtained composite wire 11. Since the clearance is so narrow, when the core wire 10 is displaced due to the pressure fluctuation in the collecting chamber, the core wire 10 comes into contact with the inner surface of the hard nipple (usually made of tool steel) 9, and seizure occurs at the contact portion. This seizure portion becomes a defect, and causes a disconnection when the composite wire 11 is drawn later. The present invention
An object of the present invention is to provide an extrusion part structure of a rotary wheel type extruder in which seizure of a nipple is prevented.
