2. Description of the Related Art As is well known, when articles such as coins are conveyed by a belt, a conveyor belt having protrusions and crosspieces on the back surface of the belt opposite to the toothed surface (hereinafter referred to as a rear protrusion belt). ) Is widely used. In the case of a thermoplastic urethane belt, the formation of such protrusions or crosspieces is performed beforehand by spotwise heating the protrusions or crosspieces made of the same material as the belt body to a predetermined portion on the back surface of the belt. It is attached by fusing. On the other hand, in the case of a rubber belt, it can be formed by polishing the back surface of the belt, and in the case of a casting type thermosetting urethane belt, it can be formed by integral molding with a mold, so it is easy to manufacture and cost-effective. As described above, the above-mentioned belt with a back projection is generally advantageous in that it is relatively easy to manufacture.

That is, instead of a device such as a coin sorter of the type described above, through a means for scraping coins from a coin tank installed below in a state of standing up one coin at a time, the standing coins are attached to a protrusion provided on the side surface of the belt. In a device such as a coin sorter in which the coins are conveyed while being held on the side surface of the belt by an appropriate pressing means so as not to fall off, the belt with the back protrusion cannot be used, and the protrusion is not on the back surface of the belt. Instead, it is preferable to use a belt with side projections formed on the side surface of the belt.

Therefore, in manufacturing such a belt with side protrusions, in forming a protrusion for carrying coins on the side of the belt, in the case of the thermoplastic urethane belt, as in the case of the rear protrusion, the tooth side face is formed. It can be mounted relatively easily by spot-wise heat-sealing the protrusions, but it has a practical problem that the fusion strength (mounting strength) becomes low because the fusion area is limited. . In the case of a thermosetting urethane belt or rubber belt,
For example, it is possible to form the protrusions by post-processing, but in this case the processing is difficult and the number of processing steps is high, so there is the disadvantage that the cost of the belt becomes high.
