Problems solved by technology

The disclosed cleaning system has the disadvantage that an additional supply of compressed air is required for all the spinning stations of the air-jet spinning machine for the delivery of the additive, and that it is thus necessary to provide a complex control device for distributing the additive doses in order to avoid the individual Overdosage of additives at the spinning station when it is stopped

Embodiment Construction

[0035] figure 1 A sectional view of a spinning station according to the invention of an air-jet spinning machine is shown (wherein the air-jet spinning machine can of course have several spinning stations, preferably several spinning stations arranged adjacently). The air-jet spinning machine can optionally include a drafting machine, to which the fiber sliver 3 is supplied, for example in the form of a double draft belt. Furthermore, the spinning station shown comprises a spinning nozzle 1 with an inner swirl chamber 5 in which the fiber sliver 3 or at least a part of the fibers of the fiber sliver 3 are carried out after passing through the inlet 4 of the spinning nozzle 1 . Twisting (the exact working mode of the spinning station will also be described in detail below).

[0036] Furthermore, the air-jet spinning machine can comprise a (not shown) pair of delivery rollers arranged downstream of the yarn nozzle 1 and a winding device (also not shown) connected downstream of...

Abstract

The invention relates to a spinning station of an air-jet spinning machine, the spinning station having a yarn nozzle (1) for producing yarn (2) from a fiber sliver (3) fed to the yarn nozzle, The yarn nozzle (1) has an inlet (4) for the fiber strand (3), a vortex chamber (5) located inside, a yarn-forming element (6) protruding into the vortex chamber (5), and a Outlet (7) of the yarn (2) produced in the interior of the cavity (5). According to the invention, the spinning station is equipped with an additive supply device (8) which is designed to supply the spinning station with additive (9), the additive supply device (8) comprising at least one valve (10) by means of which The volume flow and / or mass flow of the additive (9) can be adjusted and the valve (10) opens and closes at least once per second during its operation so that the additive (9) delivered to the valve (10) leaves the valve in pulses. Furthermore, a method for operating an air-jet spinning machine is proposed.

Description

technical field [0001] The invention relates to a spinning station of an air-jet spinning machine, said spinning station having a yarn nozzle for producing yarn from a fiber sliver fed to the yarn nozzle, wherein the yarn nozzle has a An inlet for the fiber sliver, an inner swirl chamber, a yarn forming element protruding into the swirl chamber, and an outlet for the yarn produced inside the swirl chamber. [0002] Furthermore, a method for operating an air-jet spinning machine is proposed, wherein the air-jet spinning machine has at least one spinning station, wherein the spinning station has at least one yarn nozzle, wherein during the operation of the spinning station The fiber sliver is fed to the blasting nozzle through the inlet, and wherein the fiber sliver is twisted inside the vortex chamber of the yarn spray nozzle, so that a yarn is formed from the fiber sliver, which finally leaves the spinning station via the outlet . Air-jet spinning machines with corresponding...
