Problems solved by technology

But now when using this known method and known device in the melt spinning process for producing multi-coloured carpet yarns it is noticed that in the subsequent processing the carpet shows indeterminate patterns and bands
A variant of the known method and known device, in which the nozzle holes are formed with different sizes on the circumference of the nozzle ring in order to influence the knot formation of the braided knots, does not lead to significant improvements here.

Embodiment Construction

[0034] exist figure 1 with 2 A first exemplary embodiment of the device according to the invention is shown in several views. figure 1 This embodiment is shown in longitudinal section, while in figure 2 This embodiment is shown in cross-section in FIG. The following description applies to both figures unless an explicit reference is made to a certain view.

[0035] This exemplary embodiment of the device according to the invention for producing braided knots in multifilament filaments has a rotating nozzle ring 1 which is designed annularly and has a circumferential guide groove 7 . A plurality of nozzle holes 8 lead to the groove bottom of the guide groove 7 and are formed uniformly distributed on the circumference of the nozzle ring. In this exemplary embodiment, two nozzle openings 8 are contained in the nozzle ring 1 . The nozzle holes 8 extend through the nozzle ring 1 as far as the inner sliding surface 17 .

[0036] The nozzle ring 1 is connected to the drive shaft...

Abstract

The present invention involves a method and device for knitting knitting knitting knitting on the polyfanic filament.The airstormation of the air is aimed at the long silk through the nozzle hole.In order to generate continuous weaving sequences, the airstorms periodic periodic time is generated at the intermittent time between air and diamonds.In order to generate irregular long silk structures, according to the present invention, the interval time between successive air and diamond pulses is continuously changed.To this end, the nozzle ring with a nozzle hole is connected according to the device of the present invention, which is connected to the driver device.The driving device of the nozzle ring is equipped with a control device. The control device can control the rotation speed of the nozzle ring to change the intermittent time between the air and diamond pulses.

Description

technical field [0001] The invention relates to a method for producing braided knots on multi-fiber filaments, wherein air flow pulses are directed transversely to the filaments through nozzle holes, the air flow pulses being generated periodically with pauses between the air flow pulses, A continuous sequence of braided knots is thereby produced in the advancing filament. The invention also relates to a device for producing braided knots on multifilament filaments, which device has a rotating nozzle ring with a circumferential guide groove and at least one nozzle hole opening radially into the guide groove a static pressure chamber, which can be connected to a compressed air source via a compressed air connection, which has chamber holes assigned to the nozzle ring, wherein the nozzle holes can be connected to the chamber holes by rotation of the nozzle ring to produce Air flow pulse; drive, which is coupled to the nozzle ring. Background technique [0002] Such a method ...
