METHOD OF MANUFACTURING BELT FOR POWER TRANSMISSION
Document Type and Number:
Japanese Patent JP2001212886
Kind Code:
A
Abstract:

To provide a method of manufacturing a belt for power transmission which reduces the number of working processes on the occasion of making the belt, while facilitating the work of peeling a matrix provided with projecting parts and recessed parts, after vulcanization, and increases the number of times of use of the matrix.

Regarding the method of manufacturing the belt for power transmission wherein the belt is formed by providing a cog part at least in one of a compressed rubber layer and an extended rubber layer and by embedding a core wire in an adhesive runner layer, a formed body 15 is prepared by laminating the extended rubber layer, the core wire and the compressed rubber layer sequentially on a mold. Then, the matrix constituted of a cog- shaped rubber layer 37 having the projecting part 35 and the recessed part 34 alternately at prescribed intervals along the circumferential direction is laminated integrally by vulcanization on the inside of a covering body of vulcanized rubber, and a cylindrical jacket 30 thus formed is inserted and disposed in a runner layer provided outside the formed body 15, and then vulcanized. In this way, the surface of the rubber layer is embossed by the matrix 31.
