摘要

A device for one or on a spinning preparation machine, in particular card, drafting frame comb 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 tracer roller pair is caused by periodic error value can be determined, wherein the tracer roller 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 and the output of the electronic circuitry supplies the corrected measured signal, characterized in that a contacting contact between the peripheral surface (7 '', 15'', 42 ''; 8'', 16 '', 43'') of the stationary scanning roller (7, 15, 42) and the movable scanning roller (8, 16, 43) by contact pressure of the movable scanning roller (8, 16, 43) to the stationary scanning roller (7, 15, 42) can be produced and the scanning rollers (7, 8; 15, 16; 42, 43) under..
