METHOD FOR OPERATING A WORKSTATION OF A TEXTILE MACHINE PRODUCING CROSS-WOUND BOBBINS

摘要

The invention relates to a method for determining the bobbin diameter of cross-wound bobbins on a textile machine producing cross-wound bobbins, with a creel for holding a rotatable cross-wound bobbin, a thread displacement device that can be activated in a defined manner for traversing a thread running onto the cross-wound bobbin and a drive that can be activated in a defined manner to rotate the cross-wound bobbin, wherein the two drives are independent of one another and the rotational speeds of the bobbin drive roller and the cross-wound bobbin are detected in order to calculate therefrom the ratio and ultimately the theoretical cross-wound bobbin diameter. According to the invention, the bobbin drive roller is cyclically switched on and off and in the run-down phases while the bobbin drive roller is not driven, the rotational speeds of the bobbin drive roller and the cross-wound bobbin are detected in order to calculate therefrom the ratio and ultimately the actual cross-wound bobbin diameter.
