摘要： Grooved rotary yarn distributor for the winding of bobbins of conical or varioconical shape, the distributor having a reversible, crossing helical groove, and a variable radius of the groove bottom, the conical and varioconical bobbins having a variable crossing angle of the wound yarn. The bottom of the distributing groove of the yarn distributor has a first derivative of the axial coordinate of the groove bottom is, according to the angular coordinate, an increasing function of the angular coordinate in the proximity of a selected point 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 in the proximity of the selected point, and is decreasing in the case, when the first derivative of the radius of the groove bottom, according to the angular coordinate is an increasing function of the angular coordinate in proximity of the selected point upon growth of the axial coordinate of the groove bottom only in the direction of distribution from the small end towards the large end of the conical or varioconical bobbin from zero to the maximum value of stroke of the grooved rotary yarn distributor.

摘要： 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.
