Problems solved by technology

[0004] The disadvantage of this entanglement device is that the supplied and used pre-pressurized compressed air can only be obtained from the inlet opening for the yarn into the yarn processing channel or by means of the output port through which the yarn of the entanglement device leaves the yarn processing channel. Loss of yarn handling channels which may resist the filament entanglement process to form entangled knots

Embodiment Construction

[0038] Figure 1A and Figure 1B The entanglement device 10 for entanglement of the multifilament yarn 2 is shown in schematic longitudinal or cross-sectional view according to the section lines B-B and A-A, respectively.

[0039] The entanglement device 10 has a substantially cylindrical cross-section and defines a yarn processing channel 6 with an input opening and an output opening, through which a multifilament yarn 2 is fed into and output from the yarn processing channel 6 .

[0040] The yarn processing channel 6 is delimited by a barrier wall 5 and a nozzle wall 1 opposite the barrier wall 5 .

[0041] The nozzle wall portion 1 defines a nozzle through opening 3 having a predetermined opening width DW.

[0042] Via the nozzle through-opening 3 , a prepressurized fluid working medium 4 is fed to entangle the multifilament yarn 2 , which is held above and below the entanglement device 10 by means of the thread guides 7 . 1 and 7 . 2 . Ideally, the pre-pressurized fluid ...

Abstract

The invention relates to an entangling device for entangling synthetic multifilament yarns, entangled by means of a pre-pressurized working medium, said entangling device having a yarn treatment channel configured for the transport passage and entanglement of the multifilament yarns, said yarn treatment channel being defined by a wall, the wall has a nozzle wall in which a nozzle passage opening for supplying a pre-pressurized fluid working medium is formed and a baffle wall onto which the working medium is distributed, wherein a discharge device through which the working medium and / or entrained air can be discharged is arranged in the wall defining the yarn processing channel.

Description

technical field [0001] The present invention relates to an entanglement device for entanglement of multifilament yarns by means of a fluid-like pre-pressurized working medium. Background technique [0002] Entangling devices are known from the prior art. [0003] For example DE 10 2008 018 079 A1 discloses a device for entanglement of multifilament yarns, in which a prepressurized working medium, such as compressed air, is supplied into the yarn processing channel via nozzle through-openings to induce the multifilament yarns guided therein The filaments of which form a multifilament yarn intertwine and form entangled knots. [0004] The disadvantage of this entanglement device is that the supplied and used pre-pressurized compressed air can only be obtained from the inlet opening for the yarn into the yarn processing channel or by means of the output port through which the yarn of the entanglement device leaves the yarn processing channel. Yarn handling channels are lost, ...
