Abstract: Apparatus for resistance welding consisting of two electrodes that face one another and are biased toward one another by a spring force. Each electrode is held by an electrode support through which an electro-magnetic force is generated to urge the supports away from each other and augment the bias exerted thereon, by converting the movement of the electrode supports away from one, into movement of the electrodes toward one another.

Abstract: A stamping and bending tool assembly is described for automatically making bent parts of wire or strip or like raw materials. The tool assembly comprises a plurality of bending carriages which are grouped around a circular tool carrier table with central work station and secured to the housing frame and are controlled by respective cams driven by a respective drive pinion engaged in a central ring gear. The central work station is preceded by at least one cutting tool working in timed sequence with the bending carriages and possibly by at least one take-in apparatus for raw material.
