Problems solved by technology

This arrangement of the injection channel has the disadvantage that the injection effect of the compressed air flow in the yarn delivery channel is deteriorated, so that a yarn end for piecing cannot always be reliably sucked into the yarn delivery channel and conveyed opposite the spinning direction. Spinning device via air nozzle
With the injection channels connected perpendicularly to the yarn delivery channel, it is possible that the incoming compressed air still flows through the yarn delivery channel in the spinning direction, so that no direct flow is produced in the air nozzle spinning device against the spinning direction air flow

Embodiment Construction

[0022] During the spinning process, a fluid device generates a vortex in the vortex chamber 9 , which injects compressed air by means of compressed air nozzles 15 tangentially inserted into the vortex chamber 9 . The compressed air coming out of the compressed air nozzle 15 is discharged by an exhaust channel 16, where the exhaust channel has an annular cross section surrounding the spindle-shaped part 11 containing the yarn delivery channel 10. The exhaust passage 16 is connected to a negative pressure source in a manner not shown.

[0023] The edge of a fiber-guiding surface 17 , which is arranged slightly eccentric to the thread delivery channel 10 in the region of the channel inlet 14 , is arranged as a twist resistance in the region of the swirl chamber 9 .

[0024] The fibers to be spun in the air nozzle spinning device 1 are held in the fiber bundle 3 on the one hand and enter the yarn delivery channel 10 from the fiber input channel 8 substantially without twisting, on...

Abstract

A spindle-shaped component for an air jet spinning arrangement is described. The component includes a base body and an attached tip, as well as a yarn withdrawal channel which extends through the base body and the tip, the first part of the yarn withdrawal channel being an entry opening in the tip. The spindle-shaped component also has an injection channel which runs into the yarn withdrawal channel, the injection channel being directed in the direction of the entry opening of the yarn withdrawal channel. The injection channel is formed by a surface area of the base body and a surface area ofthe tip.

Description

technical field [0001] The invention relates to a spindle-shaped part for an air nozzle spinning device, with a base body and mounted tip and a yarn delivery channel passing through the base body and the tip, the yarn delivery channel has an inlet arranged in the tip, where the spindle-shaped The component has at least one injection channel connected to the yarn delivery channel, which channel is directed towards the inlet of the yarn delivery channel. [0002] The invention also relates to a tip and a base for such a spindle-shaped part. Background technique [0003] Such a spindle-shaped part is known from the prior art DE 10 2004 044 345 A1. During the spinning process, a fiber bundle of staple fibers is fed to the air jet spinning unit where it is spun and twisted. In this procedure, the fiber bundle is first guided through a fiber delivery channel of the air nozzle spinning device into a swirl chamber, to which a fluid device for generating a swirl around an inlet of...
