Abstract
A pendulum roller head for a resistance seam-welding machine is described, having a sliding contact current transmission device between a stator and a rotor, which device is composed of an annular disc which extends radially between rotor and stator, is fastened by its outer circumference to the stator, carries an axial sliding contact ring on its inner circumference, and is flexibly designed in its bridging part between the inner and outer circumferences. The sliding contact disc is composed of a copper braid to which the axial sliding contact ring is fastened. The sliding contact current transmission device in the form of the disc with a flexible bridging part replaces the current transmission device in the form of fluid metal which has formerly been in use in pendulum roller heads.
