Abstract
Beads or ridges formed by metal work such as knurling provide peaks and valleys on a shaft of a rotary disc, which is part of an abnormal detector of wire solder, so that frictional force between the wire solder is strengthened. Further, the same peaks and valleys mating with those on the shaft are provided on a surface of a feeding roller of the wire solder. The wire solder fed by the feeding roller is provided with the peaks and valleys due to plastic deformation. Both the peaks and valleys on the shaft and on the wire-solder mate with each other so that slipping therebetween can be prevented. Since the shaft is integrated with the rotary disc which is part of the abnormal detector, the accuracy of detecting abnormalities such as clogging wire-solder or crimped wire-solder can be improved. As a result, a feeder of wire solder with better accuracy in abnormality detection can be realized.
