Traction device intended to exert a tension adjustable on a wire during winding

摘要

P the invention relates to a traction device designed to exert a tension is adjustable on a wire during winding. The device comprises two circular parallel plates 12 and 13 having the same axis and a central pierced with threaded holes in which are screwed two threaded parts 17 and 18. The metal wire 21 that is to be tensioned through the device according to its axis. A rope 11 engages in turn several times on the threaded parts 17 and 18. By rotating one of said parts in the appropriate direction, it bends the central part 23 of the intermediate portions of rope 11 around the metal wire, which is thus subjected to friction or a traction force opposing the movement. / p & & p & application to the winding of metal wires. / p
