Abstract
A method and an apparatus for winding a yarn package, wherein an advancing yarn is reciprocated by means of a traversing yarn guide within a traverse stroke, and deposited on the yarn package. To avoid high package edges, the traverse stroke of the traversing yarn guide is variable in its length within the width of the yarn package during the winding operation. The length variations of the traverse stroke occur during the winding cycle by a predetermined stroke modification function, which is determined from a mass distribution of the yarn on a hypothetically wound, ideal yarn package, so that it is possible to produce a predetermined package density of the yarn package.
