Apparatus and method for winding fiber-reinforced thermoplastic resin yarns as well as the process product

摘要

PURPOSE: To wind tows around the large, diameter of an integrated product by applying an additional force to the tows by a face means pressurized to the tows at the arriving positions of the tows at a mandrel. ;CONSTITUTION: When a carriage 12 is moved laterally to the longitudinal direction of a mandrel 16, a plurality of tows 24 made of reinforced thermoplastic resin are pulled from many feeding packages 26 mounted on a rotary take-off reels 25 against an inverse tension. Then, when a head part for thread setting is moved, the tows 24 are exposed to a radiant heater 18. In this case, the tows 24 are heated to a melting temperature by the infrared heater 18, and guided onto the mandrel 16. Then, a tool 21 is mounted on a feeding arm 14, and the surface of the tool is pressurized to the tows 24 wound around the mandrel 16 by an air cylinder 23. Then, a force is applied so that the tows 24 can be integrated at the tow arriving positions on the mandrel 16. Then, when the winding process is completed, all heat sources are removed, and the wound part is cooled.;COPYRIGHT: (C)1994,JPO
