Abstract
A slipper for current collectors having an elongated carbon brush (1) which has a hollow space surrounded on at least three sides by the brush and a carrier (3) disposed in the hollow space for supporting the carbon brush. The slipper is constructed by providing a blank of the carrier which has a cross-section that is smaller than the cross-section of the hollow space of the carbon brush. It is inserted into the hollow space and deformed so that its cross-section expands into contact with at least a portion of the surfaces of the hollow space defined by the carbon brush. An electrically conductive layer (5) can be arranged between the blank and at least a portion of the inner surfaces of the hollow space.
