Title: Method for winding up a thread

Abstract: A method and apparatus for winding a continuously advancing yarn to a package formed on a tubular core, wherein a traversing yarn guide reciprocates the yarn within a traverse stroke and deposits it on the package at an angle of crossing. For its reversal at the ends of the traverse stroke, the traversing yarn guide is decelerated within each reversal range by a finite deceleration from a guiding speed and is again accelerated to the guiding speed by a finite acceleration. The acceleration and deceleration of the traversing yarn guide are controlled in such a manner that the reversal ranges of the traverse strokes become greater in length as the diameter of the package increases.
