The yarn winding on another package interferes with and makes picking of the winding package from the front difficult.

On a false twister positioned with three levels of winding spindles in the vertical direction adjacent to each other and of which the yarn path for supplying yarn to each of these winding spindles passes in the vertical direction infront of the winding spindles, a traverse fulcrum of each winding spindle is positioned above the winding package of the lower level winding spindle in approximately the center of the width direction of the winding package, and in order to prevent interference with the picking path, is arranged with a yarn path alteration guide that flexes the yarn path upstream from the traverse fulcrum guide. The yarn path alteration guide freely moves between the winding position and the picking position and is maintained alternatively in either position by a spring.
