WIPO Patent Application WO/2006/082702
Kind Code:
A1
Abstract:
A flat belt, which can avoid the occurrence of a noise in peeling off (a strange sound), which sounds “ji-, ji-”, through the reduction of the degree of the close attachment thereof with the pulley surface of a pulley and can achieve the transmission at a low load through the enhancement of the friction coefficient. The flat belt (1) which is formed by laminating an upper rubber layer (2), a core layer (3) and an under rubber layer (4) in this order. The core layer (3) comprises an adhesive rubber (3a) and a core cord (3b) being wound spirally in the rubber. The upper belt surface (2a) and the under belt surface (4a) functioning as belt transmission surfaces are formed as rough rubber surfaces having fine concave and convex portions. The above rough rubber surface is formed by a method wherein use is made of a mold (11) for vulcanization molding having a molding surface (sleeve surface) having been subjected to the shot blast treatment or a rubber sleeve (18) for vulcanization molding and no post-working after the vulcanization molding is followed.
