Abstract
A method and device for producing cross-wound textile bobbins using a creel for holding a cross-wound bobbin, a bobbin drive roller operated by a single drive to rotate the bobbin and a thread traversing mechanism driven by a single motor. At a predetermined bobbin diameter or a predetermined thread length, a thread guide of the traversing mechanism is positioned to adjust a thread end reserve for an adjustable time span. While the thread end reserve (10) is being produced, a thread storage suction nozzle (60) particular to the winding head acts on the thread (7) running onto the bobbin (8) to intermediately store excess thread length being produced during the winding of the thread end reserve (10) and to insure a minimum thread tension to reliably fix the thread end reserve (10) on the bobbin body or the cross-wound bobbin tube.
