METHOD FOR MANUFACTURING TOOTHED BELT, CORE BODY LAYER COMPONENT, AND METHOD FOR MANUFACTURING CORE BODY LAYER COMPONENTS

WIPO Patent Application WO/2017/168924

A1

The purpose of the present invention is to provide a method for manufacturing a toothed belt, which method is capable of relatively easily suppressing variation in tension or embedment depth of core body cords while suppressing an increase in cost of a manufacturing apparatus. This method for manufacturing a toothed belt in which core body cords are embedded roughly at equal intervals in the width direction of the toothed belt, is provided with: a step for preparing a plurality of core body cords, a sheet-like core body layer component having a cover part of which the main component is a thermoplastic resin and that covers the core body cords, a sheet-like base part, and a tooth part layer component that has a plurality of teeth provided roughly at equal intervals in a conveying direction and that is arranged on one surface of the base part; and a step for heat-welding one or more of the core body layer components to a surface opposite to the surface to which the teeth of the tooth part layer component are provided. Preferably, a sheet-like backside layer component is further prepared in the preparing step, and the backside layer component is heat-welded to the core body layer component in the heat-welding step.
