  • Apparatus for the successive welding of consecutive chain links
    Patent number: 4133999
    Abstract: For the successive welding of the joints of consecutive links forming a link chain, the chain is advanced in a chain welding machine to bring a link to be welded directly below a welding position; the two links flanking the link to be welded are aligned in a common plane of alignment while a tensioning force is applied to the chain parallel to the direction of chain advance. Thereafter, the link to be welded is raised into a welding position in a plane disposed at 90.degree. to the plane of alignment. Subsequently, the link is immobilized in the welding position and its joint is welded. Upon completion of the welding step, the just-welded link is lowered from the welding position.
