ABSTRACT:
A method and apparatus for winding a continuously advancing yarn, wherein the yarn is wound into a package that is formed on a tubular core, the yarn being traversed by a yarn guide within a traverse stroke. At the beginning of each traverse stroke, the yarn guide is accelerated within a reversal length to a guiding speed, and after traversing the traverse length it is decelerated within a second reversal length. The acceleration and/or deceleration of the yarn guide are controllable, so as to modify the yarn deposit in the package edges.
