Title:
METHOD OF MANUFACTURING THERMOPLASTIC RESIN CORD WOUND BODY
Document Type and Number:
WIPO Patent Application WO/2004/101416
Kind Code:
A1
Abstract:
A method of manufacturing a thermoplastic resin cord wound body, comprising the steps of, using a core formed of a plurality of core pieces disposed along a circumference and movable forward and backward in diametral direction and having a part of a cylindrical surface formed by the outer surfaces of the core pieces in the state of the core pieces expanded in diametral direction, fixing the end part of a thermoplastic resin cord in the state of the core pieces of the core expanded in diametral direction, rotating the core to wind the thermoplastic resin cord multiple turns on the outer periphery of the core, providing ultrasonic vibration, through a horn, to the multiple layers of thermoplastic resin cord wound on the core to connect the plurality layers of thermoplastic resin cord to each other by thermal fusion using a frictional heat generated by the ultrasonic vibration, continuously winding the thermoplastic resin cord on the core, inserting the horn into the thermoplastic resin cord, and excavating the resin cord while fusing to connect the multiple layers of the thermoplastic resin cord to each other.
