  • Method of operating an appparatus for producing conveyer belts
    Patent number: 4685190
    Abstract: A method of producing steel-wire-reinforced conveyer belts. The steel wires, which are conveyed at a uniform tension through the production apparatus, each have associated with them a respective hydraulic tensioning cylinder. The cylinders, which communicate with one another, are acted upon by a pulsating fluid pressure. In this way, varying movement resistances can be reduced, resulting in extensive uniformity of the tension state of all of the wires.
