Abstract: A bobbin winding machine with a plurality of winding stations which are arranged along a bobbin winding spindle for winding a plurality of threads into bobbins is described. The winding stations are assigned a traversing device which has a flyer traversing unit for each winding station. The flyer traversing units are driven jointly and for this purpose have in each case a drive wheel which is coupled to a driven driving wheel via a toothed belt. The toothed belt is coupled to the toothed drive wheels and to the toothed driving wheel via a toothed profile side.
