摘要

In the case of a device for one or on a spinning preparation machine, in particular card, drafting frame, a combing machine or flyer, for the correction of one of a tracer roller pair to the thickness of at least one textile fiber sliver measurement signal obtained in which one of the two scanning rollers are fixed and the other scanning roller force-loaded and can be moved away from the stationary scanning roller is arranged, and the occurrence of a by means of roundness and / or eccentricity of the keys rollers pair can be determined, is caused by periodic error value, the keys rollers pair in conjunction with an electrical signal is formed (transducer) and a rotational angle encoder, the their signals to the input of an electronic system, the output of the electronic circuitry supplies the corrected measured signal.In order in a simple manner and in a short period of time detection and correction of the round barrel error is to provide a contacting contact between the circumferential surface of the stationary scanning roller and the movable (by contact pressure of the movable scanning roller) scanning roller to the stationary scanning roller and can be produced under touching contact with the scanning rollers rotatably.
