Abstract
A wire is put on a guide roller, which guides the wire in a direction of a wire reel's axis. A wire load, which changes according to the displacement of the supply angle of the wire on the guide roller, is detected sequentially. Then, the guiding speed of the guide roller is sequentially controlled to adjust the wire displacement. Therefore, when the displacement of the wire supply angle changes, the guiding speed of the wire can quickly respond to the change.
Claims3
A wire traverse apparatus of a wire saw which moves following a wire supplied from or wound up by a wire reel of the wire saw and guides the wire so that a wire supply or windup angle is substantially a right angle to a longitudinal direction of the wire reel;
- said wire transfer apparatus comprising:
- a guide roller for guiding the wire onto or from the wire reel, the guide roller moving axially, parallel to the longitudinal axis of the wire reel;
- detecting means for detecting a displacement of the supply or windup angle of the wire on the guide roller;
- and
- control means for controlling the speed of movement of the guide roller based on the detected displacement of the wire supply or windup angle so that the wire supply or windup angle is substantially a right angle.
