ABSTRACT:
In order to determine the diameter or the radius of a textile yarn cheese during winding, two sensors are placed adjacent the cheese circumference at a fixed circumferential distance from each other to detect surface characteristics of the cheese, and their sensor signals are evaluated in a correlator to form running times. The circumferential velocity of the cheese is calculated by dividing the distance between the sensors by the running times, after which the circumferential velocity and the angular velocity of the cheese are divided to compute the diameter or radius of the cheese.
