    Abstract: Roll-seam resistance welding of containers (esp. for food and drink) made of very thin sheet metal, is claimed. The seam is produced as a butt joint without use of wire. The appts. has a first rotatably driven roll head (5) with two electrodes (2,3) and an electrode cleaning device of continuous or discontinuous action, and a second roll head (8) without electrodes. By using a feed mechanism, the container shells (1) with abutting joint edges are fed to the roll heads (5,8).

    Abstract: The welding method allows the abutting or overlapping longitudinal container edges to be welded together by passing them between a current carrying outer roller (5) and a relatively movable inner roller (8), which is pressed against the outer roller with a defined force. Pref., the force exerted on the inner roller in the direction of the outer roller is adjustable and held constant during the welding process, the outer roller pref. having 2 current electrodes (2,3) on its opposite sides.

    Abstract: An oscillating electrode wheel head (210) for a resistance seam welding machine is described, which has a sliding contact current transfer device (224) between a stator (220b) and a rotor (223), which device consists of a disc (226) in the form of a circular ring which extends radially between the rotor and the stator, is attached on its outer circumference to the stator, supports an axial sliding contact ring (232) on its inner circumference and is constructed in a flexible manner in its web part (228) located between the inner and outer circumference. The sliding contact disc (226) consists of a copper mesh to which the axial sliding contact ring (232) is attached. The sliding contact current transfer device (224) in the form of the disc (226) having a flexible web part (228) replaces the current transfer device, in the form of liquid metal, which is otherwise normal in oscillating electrode wheel heads. … …

    Abstract: Described is a roller head (10) for a resistance seam welding machine, which has an internally located sliding contact current transmission device (24) between stator (12) and rotor (14), which is composed of a pair of circular ring-shaped discs (26,26') which extend radially between rotor and stator, are fastened to the rotor on their outer circumferences, carry axial sliding contact rings (32,32') on their inner circumferences, and are flexibly designed in their intermediate parts (28,28') between inner and outer circumferences. These sliding contact discs (26,26') are composed of a copper mesh, to which the axial sliding contact rings (32,32') are fastened. Thin-walled metallic diaphragms can also be used instead of the copper mesh. The roller head (10) can transmit high welding currents. As a result of the flexible design of the sliding contact discs (26,26') the contact pressure, which is created by a stack of plate springs (40), remains constant even with external mechanical influences.
