VERFAHREN ZUR ZERSTÖRUNG VON METALLGÜRTEL ENTHALTENDEN REIFEN UNTER BENUTZUNG ELEKTRISCHER ENTLADUNGEN

摘要

A device for destroying tyres with metallic cords using electric discharges, which comprises an arrangement 1 for cutting off tyre sidewalls, an arrangement 2 for delivering the tyres with cut sidewalls for destruction, a tyre destruction system 3 in the shape of a pulse-discharge unit 4 comprising capacitors 9, which system is provided with an axially symmetrical means 5 for connection to metallic cords in the form of two current conducting fixing members 13, 14 having the shape of truncated cones on the side of their working surfaces and means 7 for discharging the products of destruction. In order to improve the efficiency of destroying tyres having various dimensions, whose main portion of the cord wires, after cutting off sidewalls, cannot be brought into direct galvanic contact with the pulse current source the axially symmetrical means is provided with a current conducting protrusion 15 which is arranged coaxially relative to the two current conducting fixing members 13, 14 and which is galvanically connected to one of them while electrically isolated from the other. This device may further include a system for destroying the sidewall rings comprising a support assembly for placing cut-off sidewall rings, at least one inductor 17 connected to the pulse-discharge unit 4, and a clamp 19.
