Abstract
A gravure printing press assembly composed of an impression roller having a core portion, a support shaft for the core portion which is rotatable with respect to the core portion, and an outer conductive layer disposed about the core portion and a high-voltage contact assembly for applying a high voltage to the impression roller. The high-voltage contact assembly comprises a first assembly having a brush support member and a plurality of brushes associated with the brush support member, the brushes being held by the brush support member at a plurality of positions circumferentially disposed with respect to a central axis passing through the support shaft; a second assembly having a conductive contact ring disposed adjacent the brushes and being rotatable relative to the first assembly; and means for allowing relative movement between the first assembly and the second assembly in a direction parallel to the central axis of the support shaft.
