Patent ID: 7077168

Claim:
An apparatus for regulating the thread tension of a thread in a textile processing machine, comprising: a thread brake arrangement including a control signal input and a first thread brake element that is arranged to adjustably press against the thread so as to apply an adjustable braking force onto the thread; a force pickup transducer that is mechanically coupled to said first thread brake element so as to receive from said first thread brake element a reaction force that is oriented parallel to the thread and that is exerted by the thread onto said first brake element, wherein said force pickup transducer has a signal output adapted to provide a measurement signal representing a measurement of the reaction force; and a thread tension regulating arrangement that includes a measurement signal input connected to said signal output of said force pickup transducer and a control signal output connected to said control signal input of said thread brake arrangement, and that is adapted to provide at said control signal output a control signal dependent on and responsive to the measurement signal received at said measurement signal input; wherein said thread brake arrangement adjusts said thread brake element in response to the control signal so as to adjust the braking force dependent on the reaction force.
