An apparatus for detecting interfering particles, especially Trash parts, Nissen, Nissen shell or knobs, in textile fiber material, eg. As in cotton or man-made fibers, especially on spinning preparation machine.
An apparatus for detecting interfering particles, especially Trash parts, Nissen, Nissen shell or knobs, in textile fiber material, eg. As in cotton or man-made fibers, especially on spinning preparation machine.
u In a device for the detection of interfering particles, especially Trash parts, neps, trash Nissen or knobs. like., in textile fibers, eg in cotton or man-made fibers, especially on spinning preparation machine, wherein the detection of the interfering particles carried on optical-electronic means are the fibrous material in the form of a sliver (14) of a detection device which includes, detectable and are the measurement results of an image processing device supplied a measuring, evaluation and display device (24). In order to improve the evaluation of the measurement of the interfering particles significantly, a combing device (38; 39, 40; 39 2, 40 2) provided for the fiber sliver (14), with the two tufts (14a, 14b) having open ends in the direction of (B) and counter to the working direction (B) are produced, and are provided at both tufts (14a, 14b) determined measurement results of the interfering particles of a comparator fed and the averages thus obtained heranziehbar for optimizing setting parameters and / or components of the spinning preparation machine.
