Abstract
A textile machine includes a bobbin winder for winding a textile bobbin having a longitudinal axis, a given length and a yarn package with a peripheral surface. A drive roller assembly includes a drive roller for rotationally frictionally driving the textile bobbin. The drive roller has an active width being substantially less than the given length of the bobbin. The drive roller has contact lines for contacting the peripheral surface of the yarn package of the bobbin. The contact lines are chronologically successive during rotation of the drive roller and are shifted relative to one another in the direction of the longitudinal axis of the bobbin.
