Zusammenfassung:Bobbin winding machine in which the bobbin is driven by radially movable friction roller is provided with an auxiliary drive which drives the bobbin following its disconnection from the friction roller so that the yarn remains tensioned between the bobbin and the yarn feeding station, the drive being maintained at least until the yarn is severed. Used for cross-winding yarns in machines having a pair of alternately wound bobbins. Tensioning yarn prevents formation of loops and yarn snagging during bobbin change.
