Abstract
A method for operating a work station (10) of a cheese-making textile machine. A work station computer (32) communicates with a tensile yarn force sensor (54) for monitoring the tensile yarn force of a yarn (22) traveling from a supply bobbin (12) to a takeup bobbin (14). A yarn tensioner (36) regulates the tensile yarn force of this yarn and a yarn cutting device (52) performs a controlled severing of the running yarn. According to the invention, the work station computer (32) predetermines the contact pressure (APD) of a yarn braking device (114, 116) of the yarn tensioner (36) acting on the yarn (22) in accordance with the tensile yarn force ascertained by the tensile yarn force sensor (54), compares the predetermined contact pressure (APD.sub.ist) with a predetermined contact pressure value (APD.sub.max), and interrupts the bobbin winding process if the limit value is attained or exceeded for a predetermined time period (t.sub.2 -t.sub.1).
