Patent ID: 7163174

Claim:
A method of winding a continuously advancing yarn to form a yarn package, comprising the steps of mounting a bobbin tube at a winding position and rotating the tube about its axis, reciprocating the advancing yarn by means of a traversing yarn guide which reciprocates within a traverse stroke (H) so as to deposit the yarn on the rotating bobbin tube and form the wound package, and varying the length of the traverse stroke of the traversing yarn guide within the width (B) of the package, with the length variations (A) of the traverse stroke occurring in accordance with a predetermined stroke modification function (z) which is determined from a mass distribution (F) of the yarn on a hypothetically wound ideal yarn package, and wherein the mass distribution (F) of the yarn on the hypothetically wound ideal yarn package is computed by the steps of predetermining a desired value of the mass distribution (F desired ) from predetermined winding parameters (E) and then computing the mass distribution (F) while maintaining the limits of the desired value of the mass distribution (F desired ).
