    Abstract: On a machine for welding the longitudinal edges (12,14) of rounded body blanks (10), two groups of movable guide elements (36), which exert radial guiding forces on the blanks (10), are arranged lying opposite one another with respect to the blanks. The guide elements (36) of each of the two groups are secured to an endless chain (38). Each of these chains (38) has a chain strand extending in the direction of movement (axis A) of the blanks (10), which strand is supported by a rail (52) at both sides of a welding plane (B) containing the welding zone and normal to the direction of movement of the blanks (10). The guide elements (36) move through the welding plane (B) with the blanks (10). As a result, shock-like actions on the blanks (10) in the vicinity of the welding plane (B) are avoided; consequently, the longitudinal edges (12,14) can be welded together particularly evenly, particularly by means of a laser beam.

    Abstract: A method and an apparatus for ensuring the dimensional accuracy of a frusto-pyramidal can body (10). During the production of the body (10) this is partially heated by means of inductors in the vicinity of its base face in the region of its broader side faces (10a,10b), before the step in which it is formed into the pyramidal frustum. In this manner, a uniform reduction in the thickness of the sheet metal is achieved in the region of the base face of the pyramidal frustum during the widening operation.

    Abstract: Electric resistance welding of sheet metal coated with an electrically conductive layer is by means of a roller welding machine. While the machine is in operation, the thickness of the coating layer is determined at least on one side in a region before the welding zone. During welding the welding current source is controlled dependent on the coating thickness in such a way that the energy introduced into the welding zone is maintained substantially constant. Also claimed is an appts. for implementation of the proposed method.

    Abstract: An apparatus for guiding can bodies in a laser welding machine is described. The apparatus comprises a water-cooled holding-down shoe (22) with an integrated holding-down roller (24), gas supply (64) and suction extraction (68), the holding-down roller (24) being disposed in front of the theoretical point of intersection of the two edges of the body to be butt-welded and being adjustable in height, with the holding-down shoe (22), to the thickness of the sheet metal. Adjacent to the holding-down shoe (22) is a holding-up shoe (26) and adjacent to the holding-down roller (24) is a holding-up roller (28). Provided below the holding-up shoe (26) is a horizontally and vertically adjustable supporting roller (30) which supports the can bodies at their underside during the welding operation and during passage through the welding plane (10). The bringing together of the edges of the bodies to be butt-welded, which emerge from the Z-rail, is effected by means of this apparatus without much friction and wear, the welding position is protected and any smoke formed during the welding is drawn off. As a result of the supporting roller, too close an adjustment of the conveying means is avoided, through which increased power requirements and wear in the guide range of the Z-rail would be caused.

    Abstract: The plane rectangular pieces of metal are supplied in quick succession to a pressure point (P) between inner and outer rollers (12,13). Each piece in turn is plastically deformed to a desired constant radius (A) in passing from an entry wedge (11) to an exit guide (33) backed by a latching groove (38) and an arcuate supporting surface (39). The bent piece is then wrapped around the outside (21) of an inner mandrel (20) and elastically deformed (70) to a different shape for ejection. Its trailing end is snapped back (B) into the groove (38) as the next piece arrives at the pressure point.
