A method of operating a textile machine for producing cheeses, at whose workstations ( ) yarn ( ) is unwound from supply bobbins ( ), checked, cleaned of yarn defects and wound onto larger-volume cheeses ( ) during which the yarn defects occurring the winding process in a given yarn length are registered. When a predetermined number of yarn joinders is exceeded within a predetermined reference yarn length, the winding process is stopped and the yarn length with the excessive number of joinders, already wound onto the cheese, is removed from the cheese ( ).

Method of operating a textile machine for producing cheeses

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

In a method for braking an electric drive motor, especially a drive motor for driving a grooved drum of a winding head of a bobbin winding machine which motor is loaded for braking in a direction opposite to a rated nominal current with a braking current, the instantaneous thermal load of the drive motor is detected and the strength of the brake current is selected as a function of this thermal load of the drive motor.
