ABSTRACT:
A conveyor belt is described, which has a support fabric, which is provided with at least one thermoplastic material coating and is characterized in that onto its cutting edges is welded a thermoplastic, strand-like profile material, preferably a round cord so as to constitute an edge protection. Due to the fact that the strand-like profile material (round cord) has a lower melting point than the thermoplastic material of the coating, during welding, substantially no deformation occurs in the coating, even in the vicinity of the contact faces, whereas the profile material having a lower melting point is deformed and adapts to the shape of the cutting edge of the conveyor belt and covers the same. The inventive method makes it possible to economically provide individual endless and finite conveyor belts with an edge protection when this proves necessary.
