Abstract: A method for operating a cheese-producing textile machine which produces cheeses of the “random winding” type, wherein the contact pressure of the cheese on the yarn guiding cylinder is reduced and the cheese is simultaneously charged with a braking torque for preventing pattern windings. The angular velocity w of the cheese (4) is continuously determined and processed in a control device (18) such that, when or shortly prior to reaching a so-called pattern winding zone (BWZ), the angular velocity w1 determined by the diameter d1 of the cheese (4) is reduced by means of the definite adjustment of the contact pressure with which the cheese (4) rests on the yarn guiding cylinder (3), to an angular velocity w2 which lies below the angular velocity wk of a cheese of the critical diameter dk, driven without slippage, which causes pattern winding.

Abstract: In a method for winding a yarn onto a spool body, the conical spool body is driven about a longitudinal axis by a first drive unit. A yarn is guided onto the spool body by a reciprocating yarn guide thereby winding the yarn onto the spool body. A constant yarn winding speed is provided along the length of the spool body during the entire yarn winding process by adjusting the revolutions per minute of the spool body synchronously with a movement of the reciprocating yarn guide. The revolutions per minute are controlled by a computing and control unit based on the instant position of the reciprocating yarn guide and the diameter of the spool body at the instant position. The device for performing this method has a sensor for detecting the changing diameter of the spool body, and the reciprocating yarn guide has a detection device for detecting the instant position of the reciprocating yarn guide.
