Abstract
A sensor is provided to measure the diameter of a wire, and a radius of curvature of the center of the core wire of the wire is found from the obtained wire diameter and the radius of a measuring roller. The number of revolutions of the measuring roller is determined according to the radius of curvature. An appropriate radius of curvature is found for each wire to be processed, and an accurate number of revolutions can be found irrespective of the type of wire. Accordingly, the wire feeding accuracy is improved, and the preparation work is simplified.
