Improved method and apparatus for feeding a conductive wire for anodizing process of a slide fastener chain are disclosed in which a wire guide member reciprocates perpendicularly to the feeding movement of the fastener tape so that the distance between the upper end of the guide member and the lastly secured fastener element decreases as the guide member moves from a position spaced from the beaded portion of the tape to a position close to the beaded portion, thereby giving appropriate slack to the wire. The fastener elements are secured to the beaded portion of the tape when the guide member is in the position close to the beaded edge. Therefore, possibility of breaking the wire is minimized. |
