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.
