MANUFACTURE OF MARKED POWER TRANSMISSION BELT
Document Type and Number:
Japanese Patent JP3222790
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a marked power transmission belt having an adhered mark not deforming its shape on the surfaces of cog sections, forming the cog sections accurately in areas on which the marks are transferred and demonstrating also the cog sections in areas on which the marks are not made to adhere.
SOLUTION: In a manufacturing method for a power transmission belt, cog sections are provided at least on one of rubber layers consisting of a compressed rubber layer and a stretched rubber layer, and a core is so formed as to be embedded in a bonding rubber layer, and marks are transferred at least onto the surface of one cog section on the above-referred rubber layer. A molded body 15 composed of the stretched rubber layer, the core and the compressed rubber layer is formed on a mold, and a marking material 50 having marks 52 on a stretchable base 51 stuck on a flat surface of the rubber layer is provided on the outside of the molded body 51, and a cylindrical matrix 30 having protruded sections 32 and recessed sections 31 formed alternately at the given intervals along the circumferential direction is inserted onto the outside of the marking material and then vulcanized to improve the surface of the rubber layer by the matrix 30 and simultaneously the marks are transferred onto the surface of cog sections.
