Abstract: The present invention provides an endless belt including a reinforcing load-carrying layer which is constituted by an even number of cord-like load-carrying members (5, 6). The load-carrying members extend within the load carrying member having a load-carrying layer in a plurality but at least more than one full turn each. In order to balance unbalanced force components produced by the load-carrying members having a pitch angle, the load-carrying members are arranged in pairs. Each load-carrying member would in one transverse direction has a corresponding load-carrying member wound in the opposite transverse direction within they load-carrying layer. Only within the same longitudinal transition zone (A) of the load-carrying layer the load carrying members form a pitch angle each with respect to the longitudinal direction of the belt.

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 re 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.
