A device for cutting yarn on a ball winding machine with at least one winding station, each winding station comprising a winding flyer, a winding mandrel and a cutting device, the cutting device comprising two thread clamps, one of the thread clamps being located nearer to the winding flyer with the other of the thread clamps located nearer the winding mandrel, the clamp nearer the winding flyer having a higher clamping force for the yarn than the thread clamp nearer the winding mandrel;
- a cutting element;
- and first means for successively (a) interposing the thread clamps between the flyer and the mandrel, (b) activating the thread clamps to clamp yarn travelling from the flyer to the mandrel, and (c) feeding the yarn clamped between the clamps to the cutting element so that the yarn is severed between the clamps and the cut ends are held in the clamps.
