Embodiment Construction

[0024] figure 1 A schematic frontal detail view of the workstation 1 of the spinning machine during normal operation is shown. During normal operation, the yarn 3 is drawn from the spinning unit 4 by the yarn drawing device 2 at the yarn drawing speed. The yarn drawing device 2 is preferably constructed in the form of a pair of drawing rollers. In the embodiment shown, the spinning unit 4 is a spinneret of an air-jet spinning machine with a vortex chamber, in which the filaments of the fiber material are twisted into the yarn 3 by means of a vortex of air. This figure does not show the feeding of the fiber material, which is generally achieved by a drafting system in an air-jet spinning machine.

[0025] Alternatively, if the work station 1 is the work station 1 of a rotor spinning machine, a fiber opening device is generally used to open the fiber material into its individual filaments. Instead of a vortex chamber, the spinning unit 4 has a rapidly rotating rotor to form ...

Abstract

The invention relates to a method for operating a workstation (1) of a spinning machine, in which a yarn (3) is pulled from a spinning unit (4) at a pull-out speed during normal operation, in which the yarn (3) is monitored with respect to at least one yarn parameter by means of a mass sensor (5), in which the yarn (3) is wound onto a bobbin (7) at a winding speed by means of a winding device (6) so as to form a bobbin (8), wherein the yarn (3) is moved back and forth along a traverse width (CB) during winding onto the bobbin (7), and wherein the stop sequence is started when a yarn error-related anomaly (F) deviating from a target value of at least one yarn parameter is detected by the mass sensor (5). The winding speed is reduced during the stop sequence, wherein the yarn loop (S) is formed due to the speed difference between the winding speed and the pulling speed resulting in this way. The invention also relates to a workstation (1) of a spinning machine.

Description

technical field [0001] The invention relates to a method for operating a workstation of a spinning machine, in which a yarn is drawn from a spinning unit at a yarn drawing speed during normal operation, wherein the yarn is monitored with respect to at least one yarn parameter by means of a mass sensor, Therein the yarn is wound onto the bobbin at the winding speed by means of the winding device, thereby forming a winding, wherein the yarn is reciprocated along the traverse width during winding on the bobbin, wherein when detected by the mass sensor In the event of a yarn error-related exception that deviates from the nominal value of at least one yarn parameter, a stop sequence is initiated. The invention also relates to a work station of a spinning machine. Background technique [0002] Universal spinning machines and methods for operating the workstations of such spinning machines are well known in the prior art. The spinning machine can be designed, for example, as an a...
