Abstract
A circuit for detecting disturbances in yarn travel at a textile machine, comprising a probe delivering an electrical signal in the presence of such disturbances, the probe being operatively coupled by means of discriminator stages with a pre-selection counter structured for setting the maximum permissable number of disturbances. The pre-selection counter is operatively coupled with a multivibrator which, upon exceeding the aforesaid number, delivers a disturbance signal. A clock generator is coupled with one input of the multivibrator which is constructed as a bistable multivibrator or flip-flop and additionally is connected by means of a delay element with a resetting input of the pre-selection counter.
