Embodiment Construction

[0071] figure 1 Two essentially identically constructed spinning zones of an air-jet spinning machine are shown, the individual components of the air-jet spinning machine described below also being components of the spinning zone according to the invention.

[0072] The spinning sections each have a drafting unit for finishing the composite fibers 19 comprising a plurality of drafting unit rollers 29 (not all similarly shown drafting unit rollers 29 use a single reference numeral). Furthermore, there are spinning nozzles 2 , wherein the spinning nozzle 2 of the left spinning zone is shown in partial section. The spinning nozzle 2 has an inlet opening 22 through which the composite fiber 19 enters the spinning nozzle 2 , wherein the inlet opening 22 is preferably formed by the inlet opening 6 of the individual fiber guide element 1 .

[0073] The fiber guiding element 1 has an outer surface 3 (see figure 2 , which shows a cross-section of a possible embodiment of a spinning ...

Abstract

The invention relates to a fiber guiding element (1) for a spinneret (2) of an air-jet spinning machine, which produce a yarn (18) from a fiber structure (19), wherein the fiber guiding element (1) has an outer surface (3) supported on the fitting surface (4) of the spinneret (2) to thereby fix the fiber guiding element on or in the spinneret (2), and wherein the fiber guiding element (1) has a fiber guiding channel (5) provided with with an inlet opening (6) and an outlet opening (7) and guding, during operation of the spinneret (2), a composite fiber passing the fiber guiding element over the fiber guiding channel (5) when entering a vortex chamber (8) of the spinneret (2). The fiber guiding channel has at least one injection channel (9), with the help of which an air flow which extendsfrom the outlet opening (7) in the direction of the inlet opening (6) is generated within the fiber guiding channel (5) once compressed air is applied to the injection channel (9). Furthermore, the invention relates to an air-jet spinning machine and a method for operating the same.

Description

technical field [0001] The invention relates to a fiber-guiding element for a spinning nozzle of an air-jet spinning machine for producing yarn from composite fibers, wherein the fiber-guiding element has an outer surface for supporting on The mating surface of the spinning nozzle, so that the fiber guiding element can be fixed on the surface or inside the spinning nozzle, wherein the fiber guiding element has a fiber guiding channel with an input opening and an output opening, the fiber guiding channel is in the spinning nozzle During operation, the composite fibers are guided via the fiber guide channel from the fiber guide element when entering the swirl chamber of the spinning nozzle. [0002] Furthermore, an air-jet spinning machine with a spinning zone for the production of yarns from composite fibers is proposed, wherein the spinning zone contains at least one spinning nozzle with an internal swirl chamber, The yarn nozzle has an air nozzle facing the swirl chamber by ...
