Method and apparatus for winding a yarn into a package

An apparatus for winding a continuously advancing textile yarn into a core supported package comprising

• means for rotating the core to wind the yarn thereabout at a substantially constant rate,
• a yarn traversing mechanism for reciprocating the yarn along the rotating core and including at least one endless belt mounted for movement along a closed path of travel which includes a run extending along the rotating core, a yarn guide mounted to the at least one endless belt, and a drive for moving the at least one endless belt along said closed path of travel so as to advance the yarn guide along the rotating core, said drive including a programmable control device for controlling the movement of the yarn guide so that the yarn is moved within a traverse stroke which is axially shorter than the package length and which is reciprocated within the package length and between the ends of the package so as to define segments composed of adjacent traverse strokes in which the length of the traverse strokes is maintained without change.

A method of winding a continuously advancing textile yarn into a core supported package, comprising the steps of

• guiding the advancing yarn onto a rotating core by a traversing yarn guide which moves within a traverse stroke and so that during each traverse stroke the traversing yarn guide is accelerated to a predetermined guiding speed within a reversal length at one end of the traverse stroke, and decelerated from the predetermined guiding speed within a second reversal length at the opposite end of the traverse stroke, and
• wherein the traverse stroke has a length which is shorter than the wound length of the package, and wherein the ends of the traverse stroke are alternatingly displaced flush with the package ends and so as to define segments composed of adjacent traverse strokes in which the length of the traverse strokes is maintained without change.
