Method of winding yarn on bobbin

摘要

In a yarn take-up device in which a continuous yarn is to be helically wound on a rotating bobbin and traversed alternately in opposite directions parallel with the axis of rotation of the bobbin, a method of winding the yarn on the bobbin, comprising producing signals to control the traverse velocity of the yarn to periodically vary between predetermined minimum and maximum limits and signals to control the traverse distance of the yarn to periodically and continuously vary between predetermined maximum and minimum limits, the cycles of the periodic variation of the traverse velocity being respectively identical with the cycles of the periodic variation of the traverse distance, the maximum limits of the traverse velocity appearing in synchronism with the minimum limits of the traverse distance and the minimum limits of the traverse velocity appearing in synchronism with the maximum limits of the traverse distance.
