Abstract: A yarn traversing device (11) for a spooling device (4) of a textile machine producing cross-wound bobbins (1) comprises a yarn guide (25), which is connected by an endless tensioning means designed as a toothed belt (30) to a single drive (34), wherein the toothed belt (30) rotates in a largely closed housing (23) of the yarn traversing device (11) and is guided by guide wheels (31 or 32) arranged laterally next to a traversing area (B) and a drive wheel (41) connected to the electric motor single drive (34). The guide wheels (31 or 32) each have a smooth running surface (33), which is largely resistant to dirt, over which the toothed belt (30) runs with its toothing (38).

Abstract: A method and an apparatus for traversing a yarn, wherein a traversing yarn guide is moved by means of an electric motor. The actual position of the yarn guide is continuously determined by means of a measuring device and supplied to a control device, which performs a comparison between the actual and desired positions of the traversing yarn guide, and the control device generates a corresponding differential signal for controlling the operation of the electric motor.

Abstract: A method and apparatus for winding a continuously advancing yarn, wherein the yarn is wound into a package that is formed on a rotating 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 yarn traversing mechanism includes a belt drive system for reciprocating the yarn guide and which is controlled by a programmable control device such that the yarn guide is moved within a traverse stroke which is axially shorter than the package length and which is reciprocated between the ends of the package without changing the length of the traverse stroke.
