Manufacturing method of fiber, resin coated cord, and manufacturing method of pneumatic tire

摘要

Problem: compared with the case where the reinforcing cord is formed by filling the molten resin between the plurality of metal lines from the outside, the fiber which can suppress the occurrence of a cavity portion in which the adhesive resin does not exist inside the reinforcing cord, and the method of manufacturing the resin coating code A manufacturing method of the pneumatic tire is obtained.The fiber has a plurality of metal wires and a plurality of resin strands formed of thermoplastic resin. By heating the fiber, the resin strand is melted and an adhesive resin for bonding a plurality of metal wires is formed by the molten resin.Diagram
