Problems solved by technology

[0007] The cleaning of the surface of the yarn forming element, the surface of the nozzle interior and the surface of the fiber guide element can be carried out manually by periodic dismantling of the yarn forming element, however this in combination with the corresponding shutdowns leads to non-negligible maintenance costs

Embodiment Construction

[0032] figure 1 A part of a spinning station of an air-jet spinning machine according to the invention is shown (wherein the air-jet spinning machine can of course have a plurality of spinning stations which are preferably arranged next to each other). The air-jet spinning machine can optionally comprise a drafting mechanism with a plurality of drafting rollers 13, to which the fiber strands 3 are supplied, for example, in the form of a double drafting belt (only shown for reasons of overview). One of the out drafting rollers 13 is provided with a reference numeral). Furthermore, the spinning station shown comprises a spinning nozzle 2 with an inner swirl chamber 5 (see figure 2 ), at least a part of the fiber of the fiber strand 3 or the fiber strand 3 is twisted in the vortex chamber after passing through the inlet 4 of the yarn nozzle 2 (the exact working mode of the spinning station will also be described in detail below ).

[0033] In addition, the air-jet spinning ma...

Abstract

The invention refers to a method to operate an air spinning machine, in which the air spinning machine has at least one spinning unit with a spinning nozzle (2), in which a fiber strand (3) is fed to the spinning nozzle (2) through an inlet (4) during the operation of the spinning unit, in which the fiber strand (3) is imparted a twist inside a swirl chamber (5) of the spinning nozzle (2) by means of a swirled air current, so that a yarn (6) is formed from the fiber strand (3) that finally leaves the spinning nozzle (2) through an outlet (7), and in which an additive (9) is added with the help of an additive dispenser (9), at least temporarily, to the spinning unit while the air spinning machine is operating and applied on the fiber strand (3) and / or the yarn (6) or on sections of the spinning nozzle. According to the invention, it is suggested that the at least one physical parameter of the yarn (6) leaving the outlet (7) is monitored with the help of a sensor system (11) whereby, based on at least one measured value supplied by the sensor system (11) correlated with the above-mentioned parameter, it is determined whether and / or how much additive (9) was applied on the fiber strand (3) or the yarn (6) manufactured from this that passed through the sensor system (11). In addition, an air spinning machine to execute the method is suggested.

Description

technical field [0001] The invention relates to a method for operating an air-jet spinning machine, wherein the air-jet spinning machine has at least one spinning station with a yarn nozzle for producing yarn, wherein during the operation of the spinning station The fiber strands are conveyed via the inlet to the yarn nozzle, wherein the fiber strands are twisted (Drehung) inside the vortex chamber of the yarn nozzle by means of the vortex air flow, so that the fiber strands form a yarn, which finally passes through the outlet Leaving the yarn nozzle, and wherein, during the operation of the air-jet spinning machine, the additive is at least occasionally conveyed to the spinning station by means of the additive supply device and the additive is applied to the fiber strands and / or yarns or to the yarn nozzle on the parts. [0002] Furthermore, an air-jet spinning machine is proposed which has at least one spinning station with a yarn nozzle for producing yarn from fiber strand...
