<p>PURPOSE:To enable to wind up or draw out a cable with no twisting in a storage unit of cable for power supply or signal transmission, by winding the cable in a zigzag line on variable sheaves and stable sheaves alternatively. CONSTITUTION:A cable 11 is fixed at a testing unit with its left end, wound alternatively on variable sheaves 7 and stable sheaves 10 plurally with the middle portion, and led to the operating system through a fixed unit 13 with its right end. When a shaft 3 is rotated clockwise by a motor 4, all parallel arms 5 rotate along parallel guide grooves 2 together with the shaft 3, and each interval between the sheaves 7 and 10 is widened. In each round of rotation, the sheave 7 moves along the parallel guide groove 2 of the inside swirl within the space between the neighboring swirls, rotates plurally around the shaft 3, in a swirling locus, while the cable 11 is stored in a swirling guide 1 smoothly by a guide roller 12, and wound up with no twisting until the sheave 7 reaches the center of the guide 1.</p> |
