ABSTRACT:
A conveyor belt or treadmill belt comprises a cloth layer woven by at least one warp and woof and having an outer surface and an inner surface in response to each other, a clearance passing through the inner and the outer surfaces and being formed between the warp and the woof of the cloth layer; a pattern layer in response to the outer surface of the cloth layer including patterns formed thereon; a laminating layer melted to couple between the outer surface of the cloth layer and the pattern layer, such that the laminating layer merges into the clearance between the warp and the woof so that the laminating layer is integrally formed a rough connecting surface, the connecting surface engaging with the clearance of the cloth layer, hence another surface of the laminating layer is in connection with the pattern layer.
