<p>A process of manufacturing a looped material band for use as a conveyor belt, a conveyor, a transmission belt or the like in which the ends of the band are assembled by fitting together two serrations that have complementary shapes and are connected by at least one transverse locking rod that is inserted through transverse openings arranged in the teeth of the serrations. The process comprises the steps of producing the transverse openings by machining the ends of the band to remove material in an area corresponding at least to the transverse openings to be produced, placing a transverse core pin in each machined area, overmolding material in the machined areas to restore the ends of the band, and one removing, after polymerization of the material, the transverse core pins that form the transverse openings.</p> |
