Abstract (en)

[origin: EP0464424A1] A procedure for automatically adapting the braking force of a yarn brake located in the hollow spindle axle of a two-for-one twisting spindle to changed spindle speeds is characterised in that the vacuum generated by the suction-air stream of the rotating spindle and therefore dependent on the spindle speed acts on a braking surface (6) of the yarn brake in such a way that, with an increasing or decreasing speed of the two-for-one spindle, this braking surface is brought to bear against the brake body (7) with an increasing or decreasing pressure force. A two-for-one twisting spindle for carrying out this procedure, having a yarn brake which is located above the yarn storage disc in the region of the hollow spindle axle and which has at least one braking surface accommodated in a brake housing and a brake body bearing against the braking surface, is characterised in that the braking surface (6) forms part of a piston (14) which is displaceable in the axial direction in the brake housing (13) and which limits the top side of a vacuum chamber adjacent to the central orifice of the yarn guide channel (2.2) of the yarn storage disc (2.1) <IMAGE>
