It can be performed either at the time of molding the tan rubber or after the molding. When the molding is performed at the time of molding, it is carried out by a method in which irregularities necessary for the molding die are provided in advance and molding is performed. Further, if carried out after molding, the tooth surface is smooth Poriu
A method of post-processing by, for example, pressing a roller having a toothed shape with protrusions and depressions after molding the belt made of rubber of rubber is used. In this case, the molding die of the belt can be diverted. In the latter method, it is desirable to heat the toothed surface of the toothed belt, the gear-shaped roller with unevenness, or both of them as appropriate.

The following fine unevenness, the texture pattern is plain weave, twill weave or twill weave, satin weave or these three original design
It may be a combination of woven patterns. Further, the tooth surface to which the unevenness is applied may include at least the convex portion of the tooth portion, and may include the height portion of the tooth portion and even the concave portion which becomes the bottom surface of the tooth portion.
