Abstract
A coil feeder has been developed which permits the use of coiled bar stocks for hot-forging facilities to manufacture nuts and other parts of automobiles. This coil-feeder for hot-formers was developed with a high-accuracy frequency control system. It consists of an uncoiler, a straightener, and a pair of pinch rollers. This system improves the product yield rate dramatically compared with conventional feeders while maintaining high product quality. The control equipment is described, and test results are presented.<>
