Abstract

PURPOSE:To transmit a stable driving force in both sides equally at a fixed speed by driving wires to be wound around driving members so as to be wound successively in the twisted direction. CONSTITUTION:It is preferable to arrange driving means symmetrically about a vertical axis from the viewpoint of a space or working balance, and therefore, the wire ropes 33A, 33B also should be wound or discharged symmetrically at the outside or inside direction respectively. In order to obtain said requirement, wire members having opposed twisting directions to each other are used as the wire ropes 33A, 33B. Namely, the ''S-twisted'' wire rope 33A is used for a clockwise (Z-winding) winding drum 31A and the ''Z-twisted'' wire rope 33B is used for a counterclockwise (S-winding) winding drum 31B, so that a returning force is affected on the ''twisted direction'' of respective wire ropes 33A, 33B at the winding and the wound wire ropes 33A, 33B are put aside in the thrust direction and receive the component of force. Thus, the wire ropes 33A, 33B are adhesively wound around the winding drums 31A, 31B.
