A process for the operation of a textile machine for the manufacture of cross-wound bobbins or cheeses, which produces cross-wound bobbins in accordance with the “random winding” winding technique, in which situation, in order to avoid ribbon winding, the imposition pressure of the cross-wound bobbin on the thread drive drum is reduced, and the cross-wound bobbin Is at the same lime subjected to a braking moment, the angular velocity w of the cross-wound bobbin (4) is constantly monitored and processed in a control device (18) in such a way characterized in that when a ribbon winding zone (BWZ) is reached, or shortly before this, the angular velocity w2, which is predetermined by the diameter dl of the cross-wound bobbin (4), is reduced to an angular velocity w2, by the adjustment of the Imposition pressure with which the cross-wound bobbin (4) is on the thread guide drum (3), the said angular velocity wk, which would be featured by a cross-wound bobbin with the diameter dk driven without slippage.
