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.
Claims3
A method of operating an apparatus for producing conveyer belts of elastomeric material in which are embedded cord or wire-like load-carriers that extend parallel to one another in a longitudinal direction without contacting one another;
- said method including the steps of:
- providing means for jointly keeping said load-carriers under tension in a tension state within a lengthy portion of said apparatus;
- disposing a plurality of tensioning cylinders near an input area of said lengthy portion of said apparatus, with each of said tensioning cylinders having a piston that is displaced by pressure medium, and with each of said pistons having a piston rod;
- providing each of said piston rods with a tensioning roller that engages a respective one of said load-carriers;
- and
- applying a continously plusating pressure having a frequency between 5 Hz and 20 Hz, via said pressure medium, to said pistons of said tensioning cylinders so that always only a nominal sliding friction is present for said pistons in said cylinders, and so that greater binding static friction forces are avoided entirely.
