    摘要： A measuring device for measuring the fineness and maturity of cotton fibers is provided. The measuring device includes a measuring chamber; a supply conduit; a flow regulator arranged along the supply conduit; a first pressure sensor upstream of the flow regulator; a second pressure sensor downstream of the flow regulator; an electronic proportional pressure regulator for regulating the air pressure in the supply conduit; and an electronic processing and control unit programmed to control the electronic proportional pressure regulator as a function of the detections of the first sensor and of the second sensor or of the second sensor alternatively and respectively to keep the difference between the air pressure upstream and downstream of the flow regulator or the air pressure entering the measuring chamber substantially constant and equal to a predeterminable value.

    摘要： A measuring circuit used for the capacitive examination of a moving elongated textile test material such as card sliver, roving, yarn or woven fabric, having a measuring capacitor for accommodating the test material, and a component with a capacitance which can be changed by an electric control signal. The measuring circuit can thus be balanced in a simple, rapid, cost-effective and especially automatic way.

    摘要： A measuring head for testing yarn, having a measuring slit for accommodating the yarn and a first yarn guide element for guiding the yarn through the measuring slit. A second yarn guide element for guiding the yarn outside of the measuring slit. The yarn path outside of the measuring slit is used when at least one of a zero point calibration and an adjustment of the measuring head needs to be performed. A measuring head arranged in this manner is especially suitable for use in classifying yarn defects in the textile laboratory.

    摘要： The measured values of a property of a yarn along its longitudinal direction are detected for the characterization of a yarn moved along its longitudinal direction. The values of a parameter of the yarn are determined from the measured values. An event field is provided, whose abscissa indicates an extension of parameter values in the longitudinal direction and whose ordinate indicates a deviation of the parameter from a set point value. Densities of events in the event field are determined from the values of the parameter and its extension in the longitudinal direction. A test material body is calculated in the event field as an area, which is delimited by the abscissa on the one hand, by the ordinate on the other hand, and further by a line which substantially follows a constant event density. The area is specified numerically. At least one value of the numerical specification is output as a characteristic of the yarn.
