Embodiment Construction

[0034] exist figure 1 and 2 A first embodiment of the inventive device for processing multi-filament filaments is shown in figure 1 The embodiment is shown in longitudinal section and figure 2 The exemplary embodiment is shown in cross section. The following description applies to both figures as long as no figure is specifically indicated.

[0035] exist figure 1In the exemplary embodiment shown, a housing plate 1 and a baffle 2 are arranged in a support housing 13 . On an open longitudinal side, the housing plate 1 has a treatment channel 3 which is groove-shaped on said longitudinal side of the housing plate 1 . The process channel 3 is covered by a baffle placed on the longitudinal side of the housing plate 1 such that the housing plate 1 and the baffle 2 form an inlet 4 and an outlet 5 respectively in the extension of the process channel 3 . A nozzle hole 6 leads into the groove bottom 11 of the treatment channel 3, this nozzle hole 6 passes through the housing pla...

Abstract

The invention relates to an apparatus for treating a multifilament thread in a melt-spinning process, wherein a treatment channel is formed between a housing plate and an impact plate. The housing plate has a nozzle bore which opens into the treatment channel and is connected to a compressed-air connection. Together with the housing plate, the impact plate forms an inlet opening and an outlet opening at both ends of the treatment channel. In order to check the swirling effects which are produced on the thread by the eddying within the treatment channel, according to the invention the impact plate has a thread guiding element in the part piece of the treatment channel between the nozzle bore and the inlet opening, which thread guiding element is configured so as to protrude into the treatment channel in order to deflect the thread.

Description

technical field [0001] The invention relates to a device for processing multifilament filaments during melt spinning according to the preamble of claim 1 . Background technique [0002] In the production of synthetic filaments, in the melt spinning process a large number of fine filaments are extruded from a polymer melt, which after cooling combine to form a multifilament filament. Moistening of the filament is required for subsequent guiding of the filament in subsequent processing steps, for example for drawing over godet rollers. A finish is applied to the filaments for this purpose. In order to ensure uniform wetting of all filaments within the filament, the filament is swirled / air-jet-textured (verwirbeln) by a compressed air stream after wetting in a subsequent processing step, also known as so-called pre-jet texturing The well-known swirl texturing evens out the coating of the finish on the filament monofilament. At the same time, the strands of filaments are mixe...
