Ribbon winding prevention method and apparatus

摘要

A ribbon winding prevention method used when winding a yarn into a package P wound on a traverse drum 11 in which (1) disturb control such that the speed of the traverse drum 11 is varied slightly is performed from the start of winding (To) until a point (Ta) before the package reaches a diameter at which it tends to induce the formation of large ribbons (Tr), (2) disturb control is discontinued from that point (Ta) until another point (Tb) just before the package reaches the ribbon inducing diameter (Tr), and (3) disturb control such that the speed of the traverse drum 11 is varied greatly is performed from just before that point (Tb) until another point (Tc) after the package diameter has exceeded the point at which it induces large ribbons.
