Abstract:
1. A system to transfer an electrical voltage to or from a rotating roller, one side of the roller being connected with a bearing for the roller, comprising: a voltage transfer device that, on one side, elastically attaches to a voltage connection of the roller after connection of the voltage transfer device with the roller and which on the other side is connected with an external cable; a compensation device designed such that it compensates axial play of the roller after connection of the roller with the voltage transfer device; an electrically-conductive brush axially moveable in a fixed guide element and whose one side is aligned towards a front side of the voltage transfer device; a sealing cap closing the guide element, the sealing cap being connected to the external cable, and an internal flexible cable going to the brush from the external cable; and a brush spring arranged between the brush and the sealing cap and which exerts an elastic effect on the brush.
