Abstract
Apparatus for the successive welding of C-shaped, pre-bent interlinked chain links forming a chain. The apparatus comprises a saddle for supporting a chain link to be welded, the saddle having a trough and cup-shaped recesses at each end of the trough for accommodating the link. Guides are provided on either side of the saddle for guiding the chain links entering and leaving the saddle and clinchers are also provided for gripping the chain link during welding and following completion of the welding operation. The guide for the chain links entering the saddle is provided with a chain sprocket having crossed slots, and is pivotable about its axis to permit rotation of the link in the saddle after welding has been completed. The clinchers have claw-like recesses in their end for gripping the rounded portions of the chain link to be welded and the clincher adjacent the guide for the chain link entering the saddle has a trough-shaped recess for guiding the following link.
