ABSTRACT:
The endless drive belt is produced by winding a pre-formed load-carrying member comprising a cord embedded in a solid but softenable elastic material along and around a surface of an endless compression member belt also comprising a solid but softenable elastic material, thereby forming layer comprising a plurality of turns, and by simultaneously causing said turns to become intimately bonded to said surface. Said bonding is achieved by applying mutual pressure between said turns and said surface during winding and by selectively softening the surface layers of both said load-carrying member and said endless compression member belt which are to come into contact with each other, just prior to coming into contact with each other. The material of said surface layers is allowed to fuse. Said turns of said load-carrying member are further allowed to be partially impressed in said surface of said endless compression member belt. Softening may be carried out by the application of heat and/or the application of an adhesive. A device for carrying out the above method is also disclosed. With the device disclosed endless drive belts may be easily produced in-house at the time they are required at any size and at minimal costs and capital outlay.
