Abstract

In a supply head of a nut feeder, a guide member having both side walls guiding both end surfaces in minor axis direction of a flange portion of a transferred T-nut is fixed to the front end of a rod arranged movable forward and backward within a sleeve and magnetized for prescribed time so as to attract the T-nut to its holding surface at the top end. When the T-nut is attracted by the holding surface at the top end of the rod and the rod is moved forward to the welding position of the work, the rod is demagnetized and the T-nut becomes free thereby the T-nut abuts on the guide pin on the work by inertia force and is rotated and held to prescribed position on the work. In this case, both end surfaces in the minor axis direction of the flange portion of the T-nut are guided by both side walls of the guide member, and the T-nut is rotated in proper attitude and held to the correct welding position on the work.
