Embodiment 1

[0095] A V-shaped V-ribbed belt was produced by the same method as the production method of the above-mentioned embodiment, and this was referred to as Example 1. Specifically, in the rubber composition forming any of the back rubber layer, adhesive rubber layer, and compression rubber layer, EPDM is used as a rubber component and sulfur is used as a crosslinking agent. In addition, nylon short fibers are contained in the rubber composition forming the compression rubber layer. As the core wire, a twisted yarn made of PET fiber subjected to an adhesive treatment with an RFL aqueous solution and rubber paste was used. For the logo printing sheet, a 50 μm-thick sheet of syndiotactic 1,2-polybutadiene rubber (total light transmittance measured based on JIS K7361-1: 82%) is used, and a pigment is added. The CSM reverses the logo to print the logo printing sheet. The produced V-rib belt had a belt length of 1200 mm, a belt thickness of 4.3 mm, and a belt width of 10.68 mm with th...

Abstract

The transmission belt (B) is provided with a transparent to translucent sheet (18) so as to cover a part of the surface of the belt main body (10) including the mark (17). At least the portion (11) of the belt body (10) covered by the sheet (16) is formed of a rubber composition vulcanized with sulfur. The sheet (18) is formed of a rubber material composed of diene rubber, and is vulcanized with sulfur together with the rubber composition forming the portion (11) of the belt body (10) covered by the sheet (16) to be bonded to the belt body. (10) Integration.

Description

technical field [0001] The present invention relates to transmission belts and methods for their manufacture. Background technique [0002] Generally, a power transmission belt has a mark on the back of the belt, for example, a manufacturer's name, a product number, and the like. However, in the case of a power transmission belt in which the back is wound around a flat pulley, there is a problem that noise is generated due to a step formed by the marking portion. [0003] As a solution to this problem, for example, in Patent Document 1, it is disclosed that when manufacturing a transmission belt having a stretch layer, a core wire, and a compression layer, a marking material is attached to at least one of the stretch layer and the compression layer, and the marking material The logo of the printing rubber composition is printed on the base material impregnated with the surface rubber composition, and the base material of the marking material and the surface are vulcanized a...
