Abstract: Apparatus for feeding, welding and cutting metallic ribbon which is extremely thin. The ribbon is advanced by automatic means so that a portion thereof is nested within a slot which forms one electrode of a welding device. The welding operation is performed and then the ribbon is cut to length, the welded parts are then removed and the cycle is repeated. The means for accurately advancing the ribbon comprises a pair of rotatably mounted metallic rollers aligned along a common axis. At least one of the roller assemblies is comprised of first and second concentrically mounted rollers spaced by resilient means. The true centers of the rollers are displaced by a predetermined amount so as to provide constant tension for the feeding operation even in the case where the rollers deviate from true round which may be caused by wearing as a result of continued use.
