Embodiment Construction

[0035] figure 1 is a partial sectional view of a spinning nozzle 1 of an air-jet spinning machine, wherein this air-jet spinning machine can of course have a plurality of spinning nozzles 1 of this type. The spinning nozzle 1 has an inlet 4, which can be formed, for example, by a separate fiber guiding element 16, through which the fiber material to be spun, usually in the form of a drawn fiber bundle 3, enters the so-called vortex of the spinning position. The whirl chamber 2 implements the spinning process in the true sense again in this whirl chamber.

[0036] Drawing is usually carried out by means of a drafting device (not shown) upstream of the fiber guiding element 16 of the respective spinning position of the air-jet spinning machine, by means of a pair of take-off rollers also not shown to draw the drawn fibers The bundle 3 is drawn off from the drafting device (alternatively, it can also be drawn off by other components, such as a storage drum).

Abstract

The invention relates to a method for operating an air-jet spinning machine with at least one spinning nozzle (1), wherein the spinning nozzle (1) comprises an internal eddy chamber (2); a fiber bundle (3) is fed into the spinning nozzle (1) through an inlet (4) of the spinning nozzle (1) during operation of the spinning nozzle; the spinning nozzle (1) has one or more air nozzles (5) communicatingwith the eddy chamber (2); spinning air flows into the eddy chamber (2) through the air nozzles during operation of the spinning nozzle (1) so as to generate an air eddy in the eddy chamber (2); thefiber bundle (3) acquires a certain twist through the air eddy in the eddy chamber (2) so that yarn (6) is formed from the fiber bundle (3); and the yarn finally leaves the spinning nozzle (1) from anoutlet (7). The spinning air before flowing into the eddy chamber (2) is cooled to a temperature below 10 DEG C, preferably below 5 DEG C, and the cooled spinning air then flows into the eddy chamber(2) and cools at least one segment, of the spinning nozzle (1), in contact with the fiber bundle (3) and / or the yarn (6) and / or the spinning air.

Description

technical field [0001] The invention relates to a method of operating an air-jet spinning machine having at least one spinning nozzle, wherein the spinning nozzle comprises an internal swirl chamber, wherein fibers are drawn through the inlet of the spinning nozzle during operation of the spinning nozzle The beam is fed into the spinning nozzle, wherein the spinning nozzle has one or more air nozzles communicating with the vortex chamber, through which spinning air flows into the vortex during operation of the spinning nozzle. A swirl chamber, so that an air vortex is generated in the vortex chamber, wherein the fiber bundle obtains a certain twist in the vortex chamber by means of the air vortex, thereby forming a yarn from the fiber bundle, and the yarn Finally it leaves the spinning nozzle through an outlet. [0002] The invention also proposes an air-jet spinning machine with at least one spinning nozzle for producing yarn from a fiber bundle fed to the spinning nozzle, w...
