Embodiment Construction

[0087] figure 1 A nozzle 1 according to the invention is shown in cross section with a yarn channel 2 and an air hole 3 . The yarn channel 2 is formed by interconnected plates 8 , 9 . The air hole 3 has a longitudinal axis A and merges into the yarn channel 2 in the merging opening 4 . In the yarn channel 2, the filaments 10 (not shown, see e.g. image 3 ) is conveyed along the conveying direction B. The merging inlet 4 is located approximately in the center of the nozzle 1 along the conveying direction B and is arranged at an angle of approximately 85° relative to the conveying direction B. Entanglement air 13 (not shown, see Figure 5 ) is introduced into the yarn channel 2 through the air holes 3 in the direction of the longitudinal axis A via the merging inlet 4 . The entangled air impinges on the baffle face 5 in a vertical manner. Due to the impact of the entangled air 13 on the baffle face 5, two local flow turbulences 13', 13" are formed (not shown, see Figure ...

Abstract

A nozzle (1) for producing multi-knotted yarn (11) has a yarn channel (2) in which yarn knots can be formed by means of air entanglement. Said nozzle comprises at least one air hole (3) having a longitudinal axis (A), which merges into said yarn channel (2) at a merge opening (4). Air can be introduced into the yarn channel (2) through the air holes. The longitudinal axis (A) of the air holes (3) is arranged at an angle of less than 90°, preferably 65-85°, particularly preferably 78°, relative to the conveying direction (B) of the knotted yarn (11). The baffle surface (5) is configured in the yarn channel (2) on the opposite side of the merge opening (4) of the air hole (3) so as to be substantially perpendicular to the longitudinal axis (A) of the air hole (3).

Description

technical field [0001] The invention relates to a nozzle with a yarn channel, a method for producing a multi-knotted yarn in said yarn channel and the use of a nozzle for producing a multi-knotted yarn, having the features stated in the preamble of the independent patent claim. Background technique [0002] The individual filaments of smooth or texturized filament yarns are knotted by means of air entanglement to form knotted yarns. The air entanglement process preferably takes place here in nozzles. In the yarn channel of the nozzle, air is applied to the filaments transversely to the direction of travel. Due to localized flow turbulence, the filaments in the yarn channel are caused to rotate in opposite directions. Here, knotted yarns are formed from interlocking filaments called knots. [0003] In DE4113927 a nozzle is described which has a main channel for introducing entanglement air and two support channels opposite the main channel. The support channel directs the...
