Abstract
The present invention relates to a grooved rotary yarn distributor for winding bobbins of cylindrical shape, the distributor having a reversible, crossing helical groove and a variable radius of the groove bottom. The distributor is intended for winding of cylindrical bobbins with a constant crossing angle of the wound yarn, the bobbin being employed in textile machines. The bottom of the yarn distributing groove of the distributor has a first derivative of the axial coordinate of the bottom of the groove according to the angular coordinate in a raising function of the angular coordinate at or close to a selected point, when the first derivative of the radius of the groove bottom according to the angular coordinate is a rising function of the angular coordinate at or close to the selected point, and decreases in the case when the first derivative of the radius of the groove bottom according to the angular coordinate is a decreasing function of the angular coordinate at or close to the selected point upon the rising of the axial coordinate of the groove bottom in the direction of distribution of the yarn from zero to a maximum value of the stroke of the grooved rotary yarn distributor.
