Spinning station for air-jet spinning machines

Abstract

The present invention involves a spinning station for jet spinning machine, which is used to make yarn from fiber cotton strips, including the spinning station with a turbulent room, and its entrance to the fiber cotton strip, fiber, fiber, fiberDuring the operation of the jet spinning machine, the cotton strip enters the turbine in the direction of transmission during the operation of the jet -type spinning machine, and the spinning station has at least part of the yarn to form components in the turbulent chamber.The air nozzle in the room, the air nozzle is opened in the area of the wall of the turbulent chamber to the turbulent chamber. The air can be introduced into the turbine in a specific rotation direction through the direction of a specific rotation.With the passage, the yarn can be pulled out from the turbulent chamber by drawing the passage to guide the guidance component of the fiber cotton strip and is set in the area of the entrance of the turbine.The two guidance sections are reduced in the direction of transmission at least in some parts.

Description

technical field [0001] The invention relates to a spinning station of an air-jet spinning machine for producing yarn from a fiber composite of fibers, wherein the spinning station has a turbulence chamber with a device for making the fiber composite An inlet port into the turbulence chamber in the conveying direction during operation of the air-jet spinning machine, and the spinning station also has a yarn forming element extending at least partially into the turbulence chamber, wherein the spinning station has leading into the turbulence chamber air nozzles which open into the turbulence chamber in the region surrounding the wall of the turbulence chamber and can be introduced into the turbulence chamber by air in the predetermined direction of twisting in order to rotate the yarn along said direction of twisting Twisting is applied to the fiber composite in the region of the inlet mouth of the thread forming element, wherein the thread forming element has a withdrawal channe...

Problems solved by technology

In other words, if the twist is to be conveyed in the opposite direction to the conveying direction, the associated counter-twisting of the fiber strands would necessarily result in a reduction of the desired entangled fibers and / or in the drafting device upstream of the turbulence chamber. Reduced drawability of fiber strands in the zone

[0005] The twist-retaining elements acting on the fiber strands from the outside and known from the prior art limit the corresponding transmission of the twist, but on the other hand the reduction of the entangled fibers must generally be accepted (see especially the aforementioned EP 0 990 719 B1)
