    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: The carrier (12) has a supporting element (14) which is to be attached to a conveying device, for example an endless chain. A thrust element (16) of wear-resistant material is attached to the supporting element (14) in such a way that when the latter moves forward, it engages with a rear edge of a sheet (10) to be conveyed. The thrust element (16) is supported on the supporting element (14) in a backwardly resilient manner via at least one elastic intermediate layer (18). In a preferred embodiment of the carrier (12), the thrust element (16) has an elastic sleeve (30) of metal, which is supported on an axle (20) attached to the supporting element (14) near its two ends by in each case an intermediate layer (18) which takes the form of an electrically insulating ring wheel. As a result of this, rapid accelerations are made possible when conveying thin sheets in a can welding machine, without the said sheets being damaged by the carrier (12). … …

    Abstract: A roller head (10) for a resistance seam welding machine has an internally located sliding contact current transmission device (24) between stator 12) and rotor (14) and 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 flexible 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 presssure, which is created by a stack of plate springs (40), remains constant even with external mechanical influences.
