Abstract: The invention relates to a spinning means for a work station of a textile machine having a plurality of work stations, comprising a first spinning means identification for identifying and/or authenticating the spinning means at a work station. Furthermore, the invention relates to a textile machine having a plurality of work stations and a method for operating the same, wherein the work stations have replaceable spinning means, each having a first spinning means identification. In order to provide a spinning means that has a particularly forgery-proof spinning means identification, it is provided that the first spinning means identification is formed by at least one specific, sensor-detectable material property of a spinning means material and/or a coating applied to the spinning means material. In order to provide a method for operating a textile machine which prevents operation with unsuitable spinning means, it is provided that the first spinning means identification formed by a material property of the spinning means is monitored by a sensor device and, depending on the detected material property, operation of the respective work station is blocked or limited.

Abstract: A first operating device for operation of a textile machine includes a basic mode function and an expert mode function for operation of the textile machine by a user. A switching function allows the user to switch between the basic and expert mode functions. A remote transmitting function provides for communication to a second operating device assigned to a remote textile machine so that the user at the textile machine can operate the remote textile machine in the basic or expert mode via the first and second operating devices. A remote receiving function provides for communication from the second operating device assigned to the remote textile machine so that a remote user can operate the textile machine in the basic mode or expert mode from the remote textile machine via the second and first operating devices.

Abstract: 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.

Abstract: Various systems and methods described herein use electrostatic forces to separate fibers with minimal to no breakage and align the individual fibers with minimal handling. These systems and methods allow for testing, such as measuring the length, of individual fibers without the biases caused by breakage or bundling in prior art systems. These systems and methods may also be useful in applications requiring fiber alignment with minimal material handling. One exemplary system includes a pair of nip rollers and a collector that are spaced apart from each other to define an air gap therebetween. The nip rollers are grounded or negatively charged, for example, and the collector is positively charged to create an electrostatic field in the air gap. The electrostatic field separates the fibers, elongates the fibers end to end, and urges the fibers toward the collector.

Abstract: A method which improves the correspondence between the produced fancy yarn and the predetermined configuration of said fancy yarn. The fancy yarn is guided through a sensor device in a spinning device after it is formed and the diameter of the fancy yarn is continuously measured by the sensor device. The fancy configuration of the produced yarn is determined on the basis of the measured values of the diameter and is compared with the predetermined fancy configuration. The comparison is carried out until sufficient correspondence between the predetermined fancy configuration and the fancy configuration of the optimized, produced yarn is achieved.

Abstract: At least one yarn is unspooled from at least one bobbin using a spindle cap. The unspooling speed and, in a coordinated manner, other parameters associated with the transformation process, are adjusted according to a quantity representative of the amount of yarn remaining wound on the at least one bobbin, so that the unspooling speed remains below limits imposed by unspooling conditions.

Abstract: A method for visually displaying the maintaining of specified effects in a produced fancy yarn by measuring the deviations of the yarn diameter from the desired specifications. The display is a two-dimensional classifying matrix which is known per se. The display matrix is divided into longitudinal regions in one dimension and diameter regions in the other dimension, and forms a class in each case by combining a longitudinal region with a diameter region, wherein each deviation from the desired specification is allocated to a class. Only the effect regions of a fancy yarn are included in the classifying matrix, with only the regions of the fancy yarn counting as effect regions, the diameter of which is at least a specified amount over a specified web diameter and the length of which exceeds a specified minimum length.
