ABSTRACT:
After formation of a yarn pre-build a yarn tail is produced on a package tube. The yarn is guided with the aid of a yarn traverse guide and caught by an auxiliary yarn guide during formation of the yarn pre-build. It is important that, after the formation of the yarn pre-build and before reaching the traverse end, the yarn is brought out beyond the latter by means of the auxiliary yarn guide which follows the yarn traverse guide in the running direction of the yarn. It is also important that, while being caught by the auxiliary guide, the yarn remains in the yarn traverse guide. In this manner the yarn tail is formed outside the traverse width. Thereafter the auxiliary yarn guide releases the yarn to the yarn traverse guide and the final package is built.
