Embodiment Construction

[0034] figure 1 A longitudinal sectional view of a spinning nozzle 1 for an air spinning machine according to the invention is shown. If the spinning nozzle 1 is integrated in an air spinning machine, the strand-shaped fiber bundle 3 is fed to the spinning nozzle 1 in a predetermined transport direction T. The fiber bundle 3 is usually supplied by means of a drafting mechanism (not shown) into the region of the inlet 2 of the spinning nozzle 1 , which region is formed by so-called twisting elements 20 , and passes here into the interior of the spinning nozzle 1 . The inlet 2 can be partially delimited by a separate fiber guide element 15 .

[0035] A swirl chamber 4 , ie a cavity, is located in the interior, into which a spindle-shaped thread forming element 5 protrudes. There are also air nozzles 7 via which compressed air can be introduced into the swirl chamber 4 in the form of a swirling air flow during the operation of the spinning nozzle 1 . The outlet opening 8 of th...

Abstract

The invention relates to a swirl element (20) for a spinneret (1) of an air-jet spinning machine, the swirl element (20) comprising an inlet (2) for a fiber structure (3), the swirl element (20) having air nozzles (7) each with an outlet opening (8), which serve to introduce air into a swirl chamber (4) of the spinneret (1) when the swirl element (20) is used as intended in order to move out of the swirl chamber (4) via the inlet (2) in a transport direction ( T) incoming fiber structure (3) to produce a yarn (10). According to the invention it is proposed that the swirl element (20) comprisesa section (11) made of a ceramic material, the section (11) on a side of the outlet openings (8) of the air nozzles facing away from the inlet (2) in relation to the transport direction (T) (7) is arranged. A spinneret for an air-jet spinning machine is also described.

Description

technical field [0001] The invention relates to a twisting element for a spinning nozzle of an air spinning machine, wherein the twisting element comprises an inlet for a fiber bundle, wherein the twisting element comprises air nozzles each having an outlet for the air nozzles During normal use of the twisting element, air is introduced into the swirl chamber of the yarn nozzle, so that a yarn is produced within the swirl chamber from the fiber bundle entering via the inlet in the transport direction. [0002] In addition, a spinning nozzle for an air spinning machine is proposed, wherein the spinning nozzle has an inlet for the fiber bundle and a built-in swirl chamber, wherein the spinning nozzle has an at least partially extending into the swirl chamber The yarn forming element has an inlet opening for the fibers of the fiber bundle, wherein the spinning nozzles comprise air nozzles each having an outlet opening through which air can be introduced into the vortex chamber so...
