LONG MATERIAL TRANSFERRING DEVICE

摘要

PROBLEM TO BE SOLVED: To stably wind up a long material such as a wire with the simple structure. SOLUTION: A winding side winding frame 8 is rotated by a motor 9 to draw a wire 1 from a supplying side winding frame 2. A dancer-cum-tension detecter 6 applies the tension to the wire 1. A supplying side motor 3 is controlled to constantly maintain the tension of the wire 1 on the basis of the detected tension value. When the tension of the wire 1 is unusually lowered, the motor is stopped.
