Abstract

The process for forming, or rendering endless or repairing a conveyor belt made of rubber and equipped with stress bearing inserts comprises providing a conveyor belt section with rubber material and preparing it for vulcanization, bringing it between heatable press platens and vulcanizing it using heat and pressure. The rubber has Newtonian flow properties and undergoes a hot pressing. The conveyor belt section is vibrated during vulcanization over a vibrational time period which is smaller than the vulcanization time.
