摘要： A method for operating an air jet spinning machine having at least one spinning unit with one spinning nozzle for producing a yarn is provided. During the operation of the spinning unit, the spinning nozzle feeds a fiber composite through an inlet in a predefined transport direction. The fiber composite within a vortex chamber of the spinning nozzle receives a twist with the assistance of a vortex air flow, such that a yarn is formed from the fiber composite. With the assistance of at least one sensor system, the yarn leaving the outlet is monitored with regard to defined yarn flaws. The production of yarn is interrupted upon the detection of a corresponding yarn flaw. Between the detection of the specified yarn flaw and the interruption of the yarn production, a cleaning process is carried out during which an additive is fed to the spinning unit and is applied to the fiber composite and/or the yarn produced from the fiber composite and/or on parts of the spinning nozzle.

The invention proposes that the spinning station (1) has an information unit (7) with the aid of which it is possible to display to an operator of the spinning station (1) how much yarn (3) has to be at least unwound from the package (16) located in the winding apparatus (20) following the interruption to the yarn production in order to ensure that the yarn section having the yarn defect has been completely removed from the package (16). Furthermore, a yarn clearer and a method for operating a spinning station are proposed.

摘要： In an apparatus for detecting a parameter at a plurality of slivers fed to a drafting system of a spinning machine, especially for detecting the movement and/or the presence of a sliver, in which the parameter is measurable separately at each sliver, each sliver is drawn out of sliver cans over a respective driven feed roller and fed to the drafting system and is mechanically sensed by a feeler element, the deflections of which are convertible into electrical signals. To allow an improved and more accurate detection of the individual slivers in a structurally simple manner, a distance sensor that is a contactless distance sensor is provided to detect the position of each feeler element, the sensor being connected to an electrical evaluating unit.

摘要： The invention relates to a device for measuring the thickness and/or irregularity of slivers, with a compacting part (2) compacting the sliver and with a measuring part which has a gutter-like guide conduit (8) for the compacted sliver and a sensing member (10) which senses the sliver mechanically and which is adjustable relative to the guide conduit. In order to allow more accurate measurement, the sensing member is likewise of gutter-like design in a region in contact with the sliver and forms a kind of guide conduit (15), so that, in the measuring part, the sliver runs through a guide conduit consisting of a fixed part (13) and of a part (14) adjustable relative to the fixed part (13). The adjustable part is fastened to deflectable carriers (11, 12), and the measurement of the thickness and/or irregularity of the sliver is carried out by measuring the adjustment of at least one of the said carriers.

摘要： A drawing frame includes an inlet measuring organ sensing a property of a plurality of slivers as they are simultaneously introduced into the drawing frame and emitting a measuring signal representing a magnitude of the property; a regulating drawing unit including a plurality of drawing rolls defining a drawing region along which the slivers are drafted as they run through the drawing frame, a drive for rotating the drawing rolls and a control arrangement for regulating the drive as a function of the measuring signal for varying the draft of the slivers in the drawing region such that mass fluctuations in the slivers are equalized. The control arrangement changes the measuring signal into an actual control signal as a function of operational conditions to compensate for influences derived from the operational conditions and affecting measuring results. The control signal is applied to the drive.

摘要： The present invention provides a drafting apparatus and method having a plurality of pairs of rollers which pairs are each driven in the same rotational direction and have silver contact points oriented along a common straight line. Sliver is fed to the primary rollers through a trumpet guide connected to a strain gage to determine the size of incoming silver and adjust the draft ratio accordingly to equalize the output silver weight. A silver presence and position detecting device operative on a reflected signal is provided adjacent the output of silver, which sends a signal through a computer to adjust the speed of the silver take up apparatus.

摘要： In a textile fiber preparation machine, thickness and/or unevenness characteristics of a lap (W) formed by a web or wadding of textile fibers being fed in the machine are determined for individual longitudinal strips spaced across the width of the lap. A plurality of individual sensors (2) are arranged next to one another over the width of the lap (W) and press the lap (W) against a stationary guide (4,5, 6--6'). Each of the sensors (2) is movable toward and away from the guide and is resiliently biased toward the guide. The amount of movement of an individual sensor (2) away from the guide by the lap is a measure of the thickness of the lap portion being contacted by that sensor. The use of individual sensors arranged end to end across the width of the lap improves sensitivity so that even brief changes in thickness when the lap has a high transport speed can be measured reliably. Furthermore, the apparatus can be adapted quickly and simply to changing lap widths.

摘要： The profile of a measurement roll is stored in a computer during a calibration revolution. On revolution with fiber mats to be measured, the computer reduces the measured values exactly by the measured values of the corresponding calibration profile. The measurement result obtained does not depend on the production quality of the measurement roll.

摘要： An arrangement for continuously determining the density of an elongated strip-shaped web of fiber sliver in the course of a spinning process in order to generate control signals for use in controlling the operation of machine elements operative for equalizing the distribution of the fiber sliver includes two of stepped rollers which together delimit, at a their nip region, a confining space for the passage of the fiber sliver web therethrough. One of the rollers is mounted on a support for rotation about a stationary axis and is driven in rotation, while the other roller is mounted on the support for free rotation about another axis which is parallel to the stationary axis and defines an imaginary plane therewith, as well as for movement along the imaginary plane against a spring force away from the one roller, so that the fiber sliver is compressed and moves the other roller to a greater or lesser degree away from the one roller as it passes through the confining space, depending on its density. A contactless proximity sensing element is arranged along the imaginary plane and has a sensing surface which faces a portion of the peripheral surface of the other roller so as to detect the extent of displacement of the other roller relative to the one roller and issue an electric signal representative of the detected value.
