摘要： A grooved traverse drum for winding yarn on to a bobbin comprises a yarn guide groove spirally formed in an external surface thereof and including inversely running forwarding and returning paths connected with each other at a pair of turning points situated at opposite ends of the drum, portions of the forwarding and returning paths immediately following the respective turning points having a greater lead angle so that the yarn being guided moves towards the center of the drum as quickly as it passes the turning points, thereby preventing the formation of stitch at end surfaces of a yarn package being produced.
