Embodiment Construction

[0026] exist figure 1 A block diagram of an apparatus according to the invention for producing air-jet texturing of multifilament filaments is shown in . The filament treatment takes place within the treatment channel 3 which is formed between the nozzle holder 1 and the cover part 4 . A nozzle hole 2 is provided on the nozzle holder 1 , which opens at one end into the treatment channel 3 and at the other end is connected to an air delivery device 5 . The air delivery device 5 is not shown in detail here and will be explained in more detail in the following exemplary embodiments.

[0027] The air delivery device 5 is associated with a pressure chamber 6 and a volume accumulator 7 . The pressure chamber 6 has a chamber volume which is figure 1 in the reference mark V 1 express. In contrast, the volume storage device 7 has a much larger storage volume, which in figure 1 in the reference mark V 2 express.

[0028] On the inlet side the volume accumulator 7 is connected vi...

Abstract

The invention relates to a device for producing air-jet texturing of multifilament filaments, which has a treatment channel, nozzle openings leading into the treatment channel, and an air feed. The air delivery means cooperates with the nozzle holes to generate a pulsed flow of compressed air, wherein the compressed air is generated by the pressure chamber and the pressure source. In order to control, in particular, the pressure pulses generated in the pressure chamber, a volume accumulator is arranged between the pressure chamber and the pressure source, wherein the volume accumulator has a storage volume which is greater than the volume of the pressure chamber.

Description

technical field [0001] The invention relates to a device for producing air jet deformation / entanglement (Verwirbelungen) on multifilament filaments, the device having a treatment channel, a nozzle hole leading into the treatment channel and an air delivery device, which is connected to the nozzle The holes cooperate to generate a pulsed flow of compressed air, and the air delivery device has a pressure chamber connected to a pressure source. Background technique [0002] Such a device for producing air-jet texturing of multifilament filaments is known from US Pat. No. 5,134,840. [0003] In the production of synthetic filaments, the synthetic filaments are formed from a plurality of individual strands which are interconnected for subsequent processing by braiding knots or air-jet texturing to form the filament compactness. In order to produce this filament compactness on multifiber filaments, it is known to produce air jet texturing on multifiber filaments by means of compr...
