Abstract
In a link forming apparatus, U-shaped links are fed into a forming station and closed by a forming anvil. Opposing electrodes are then pressed against each side of the closed link by means of a common belt drive which is in turn pneumatically driven. Each electrode is spring biased with respect to a carrier so that a predetermined spring force is applied to the link by the electrode during the welding operation. The first electrode to contact the link and apply a predetermined pressure triggers the welding current.
