Abstract

PURPOSE: To simplify manufacturing processes exceedingly by a method wherein the rubber tube is plasticized, reinforcing threads are wound and projected rubber material is vulcanized and molded smoothly.
CONSTITUTION: On the outside of a mandrel 15 unvalcanized rubber is extrusion- molded by an extruder 16 into a thick rubber tube 17, heated by a heating tube 19 for plasticization and the reinforcing threads 20 are coiled in a network form around a softened rubber tube 17. Then unvulcanized crude rubber projects from the network of the reinforcing threads 20. This rubber tube 17 is cut in a suitable length, placed in a die and vulcanized in the die under pressure. The crude rubber projected from the network of the reinforcing thread 20 is crushed, the external circumference of the rubber tube 17 is vulcanized and molded in a smooth cylindrical form and a unified reinforcing thread-mixing rubber hose is obtained by pinching a reinforcing thread layer 20a between an internal rubber tube 17a and a cover rubber tube 17b. In this method, double extrusion moldings are not needed for the rubber tube as before and an adhesive coating process and a drying process are not required.
