A molded part () for a nozzle core () for crimping threads. The molded part comprises a ceramic body () having a planar surface (). Receiving contours (), for receiving a fastening mechanism (), are arranged in the planar surface (). The receiving contours () are open in the lateral direction.

The invention relates to a texturing device () for texturing at least one continuous yarn consisting of a plurality of filaments. This texturing device () has at least one housing () and at least one nozzle core (), which can be charged with a fluid. The nozzle core () includes a yarn channel () and at least one fluid feed channel (), opening into the yarn channel with a radial component. Furthermore, the nozzle core () includes an outlet region () of the yarn channel () and an inlet region () with an inlet opening () of the yarn channel (). The distance between the inlet opening () of the inlet region () and the fluid feed channel () of the nozzle core () opening into the yarn channel () is at most 12.5 mm. The region (), which is located ahead of the inlet region () of the nozzle core () in the direction of filament movement, has a radial outer delimiting area (). This lies outside a cone of 20&#xb0; narrowing in the direction of filament movement. The outer delimiting area () preferably lies outside a cone of 30&#xb0;.

Texturing device and method for texturing continuous yarns

The invention relates to a ceramic nozzle core and a method for producing a ceramic nozzle core which is part of a device used for producing loop yarn. The inventive ceramic nozzle core is embodied with an approximately constant wall thickness and a reduced size so as to perform the central functions of the yarn processing duct comprising air injection and a yarn outlet for forming loops while being produced in a molding process. In a particularly preferred method, the ceramic nozzle core is injection-molded with high precision. The inventive ceramic nozzle core can be configured in a miniaturized fashion and as part of a two-piece nozzle core, the ceramic nozzle core being inserted into an outer nozzle core jacket. The two-piece nozzle core can be incorporated into a housing known in prior art, for example, as a replaceable nozzle core.

The invention relates to a method for the texturing of endless yarn by means of a texturing nozzle having a continuous yarn duct into which compressed air at a pressure higher than 4 bar is blown in the direction of the yarn conveyance, whereby the yarn duct is preferably conically widened at the outlet end with a widening angle larger than 10&#xb0; for generating a supersonic flow. The invention furthermore relates to a texturing nozzle for the texturing of endless yarn with a continuous yarn duct having an inlet end, a central, preferably cylindrical portion with an air supply orifice as well as a preferably conical outlet end with a widening angle larger than 10&#xb0;, but smaller than 40&#xb0;.

Texturing nozzle and method for the texturing of endless yarn

The invention relates to a pin assembly which keeps single-piece, two-piece or multi-pieced yarn processing elements, especially yarn interlacing spinnerets or thermal treatment elements, in an exact position during an entire service life, despite the extreme effects of preparations used. Instead of a traditional soldered joint or an adhesive connection, mechanical clamping means are used to fix the dowel pins to one part of the spinneret. Fixation of the dowel pins is not affected by heat or chemical preparations. The clamping means consists of a simple clamping ring holding the dowel pin in position directly inside the body of the spinneret between the clamping pin and an after-body. The novel positioning solution can be used with individual parts of spinnerets, parts of spinnerets in machines or multiple parts of spinnerets. The dowel pins enable the entire spinneret to be substantially miniaturized and allow narrow separation between various yarn runs, which was previously impossible. The invention can be used advantageously in interlacing spinnerets or in stream treatment elements.

Yarn processing device and use thereof

A method and machine for treating yarn may include feeding the yarn through both a heat treatment and an air jet texturing nozzle. The texturing nozzle may be supplied with compressed air, producing an air jet with a speed greater than Mach in the yarn channel. The heat treatment may be performed before and/or after feeding the yarn through the texturing nozzle.

Method and apparatus for the manufacture of a mixed yarn using

In a selvage laying equipment a catcher nozzle (44) with a catcher channel (45) lying in axial prolongation of the nozzle and a threader nozzle (41) with a catcher channel (42) lying in axial prolongation of the nozzle are arranged in a carrier (54) with the axes of their air jets crossing one another, which enables a narrow construction of the device for threading the end (21a) of the weft yarn into the eye or hook of the selvage laying needle (11) and hence short ends (21a) to the weft yarn and narrow selvages, respectively. Bits of dirt such as fluff are reliably carried away from the gap (55) in the carrier (54) as well as from the catcher channels (42, 45) and the formation of an air dam is prevented.
