Patent ID: 7997055

Claim:
Method for the thermal treatment of a running yarn ( 14 ) on a twisting machine with a large number of workstations, which in each case have a device ( 1 ) for the thermal treatment of the running yarn, which is preceded or followed, respectively, by a delivery system ( 2 , 3 ), whereby the yarn ( 14 ) passes through the device ( 1 ) substantially without tension, and in that the yarn ( 14 ), after passing the downstream delivery system ( 3 ), is wound, characterised in that the passing yarn ( 14 ) is loaded with a defined force of an order of magnitude up to 1 cN by position-variable means ( 24 , 25 , 27 ), the position change of which caused by a change in the yarn tension because of disruptive influences during the thermal treatment of the yarn ( 14 ) being used as a control variable for controlling at least one of the delivery systems ( 2 , 3 ).
