Abstract: A winding bar is clamped in a tangential direction in a winding slot in a rotating machine, which is also provided with an axially directed slot wedge arranged at the opening of the slot, by providing a radially directed positioning groove in one of the slot walls with a wedge device in this groove exerting pressure on the winding bar. The wedge device comprises two side wedges, which may be connected into a single unit, and which have sliding surfaces facing each other converging in tangential and radial directions and engaging an intermediate wedge which can be inserted in the radial direction between the two side wedges.
