ABSTRACT:
A method of producing a thread-reinforced, extruded rubber body by a shear head wherein the threads are continuously supplied, embedded in a rubber mixture which is in a continuous forward motion and fixed in the rubber body by vulcanizing the rubber mixture. The method is such that the reinforcing threads are helically twisted in the finished rubber body. The rubber body is thus reinforced not only in longitudinal direction but also additionally in circumferential direction.
