A method for operating a work station ( ) of a cheese-making textile machine. A work station computer ( ) communicates with a tensile yarn force sensor ( ) for monitoring the tensile yarn force of a yarn ( ) traveling from a supply bobbin ( ) to a takeup bobbin ( ). A yarn tensioner ( ) regulates the tensile yarn force of this yarn and a yarn cutting device ( ) performs a controlled severing of the running yarn. According to the invention, the work station computer ( ) predetermines the contact pressure (APD) of a yarn braking device ( ) of the yarn tensioner ( ) acting on the yarn ( ) in accordance with the tensile yarn force ascertained by the tensile yarn force sensor ( ), compares the predetermined contact pressure (APD ) with a predetermined contact pressure value (APD ), and interrupts the bobbin winding process if the limit value is attained or exceeded for a predetermined time period (t &minus;t ).

Method for operating a workstation of a cheese-producing textile machine

A method for operating the winding heads of a bobbin winding machine each of which respectively has a yarn tension sensor connected to a work station computer for detecting the actual tension in a yarn traveling from a delivery bobbin to a take-up bobbin, a yarn tensioner for regulating the yarn tension, a splicing device for automatic connection of yarn ends following a yarn break and/or a yarn cleaning cut, and a delivery bobbin changing device. After a splicing of the broken or cut yarn ends, the actual yarn tension is detected by the yarn tension sensor, and the detected value is compared in the work station computer with a threshold value which, if exceeded, results in actuation of the delivery bobbin changing device to provide a fresh delivery bobbin.
