Abstract: A device for delivering spring clamps is disclosed, which spring clamps are welded to a pipe frame for a vehicle seat so as to extend spring members across such pipe frame. In this spring clamp delivery device, a movable delivery mechanism is operated to charge the spring clamps that are discharged via a transfer rail from a supply hopper individually into a plurality of chutes which are provided in the movable delivery mechanism substantially at the same intervals as those of the spring clamps relative to the pipe material, and then to deliver such spring clamps to the pipe material that has been set in a welding machine. Thus, even if varied in size, the spring clamps can be delivered to the pipe material in such a positive manner that they can be positioned to correspond to the predetermined positions of the pipe material.

Abstract: A jig for automatically welding pipe frames used to form vehicle seats is disclosed. In this jig, there is provided on a frame carrying plate a guide element having the reference plane of one of two side portions of a frame, so that the one side portion of the frame can be welded while it is in abutment with the guide element. To weld the other side portion of the frame, the frame carrying plate is moved and two adjusters provided in a bed plate are used for the reference. With such structure, while a welding machine remains fixed, by changing the references according to the portions to be welded in the width direction of the pipe frame, it is possible to weld the two side portions of the frame accurately.
