Embodiment Construction

[0024] exist figure 1 and figure 2 In , a first embodiment is schematically shown in several views. Both illustrations show the embodiment in action. in figure 1 shows a partial cross-section of the entire device and figure 2 A side view is shown. The following description applies to both figures unless it is specifically indicated which figure is referred to.

[0025] according to figure 1 and 2 The embodiment of the present invention has a conveyor nozzle 1 coupled via a fluid connection 2 to a fluid source (not shown here). Conveyor nozzle 1 comprises a continuous guide channel 30 which in figure 1 and 2 shown in dotted line. The guide channel 30 penetrates the conveyor nozzle 1 and thus forms an inlet at the upper end. The lower end of the guide channel 30 of the conveyor nozzle 1 opens into the stuffer box 3 . The stuffer box 3 is in figure 1 and 2 is likewise shown in dashed lines and is constructed in the housing 31 . The housing 31 has a thread plug ou...

Abstract

The invention relates to a crimping device for crimping a multifilament bundle in a melt spinning process. For this purpose, the crimping device has a conveyor nozzle and a stuffer box which is assigned to the conveyor nozzle for stuffing the tow conveyed by the conveyor nozzle. For the heat treatment, a treatment unit with a rotatable treatment drum with a rotating drum wall for guiding and temperature-regulating the thread plug is arranged downstream of the stuffer box. In order to be able to carry out the treatment of thread plugs as gently as possible, according to the invention, the stuffing box is arranged axially parallel to the treatment drum, so that the stuffing can be fed with a linear stroke from the thread plug outlet of the stuffing box to the bottom of the drum wall. week department. The naturally acting gravitational force of the thread plug can thus be used advantageously for guiding the thread plug.

Description

technical field [0001] The invention relates to a crimping device for crimping and deforming a multifilament bundle in a melt spinning process, the crimping device has: a conveyor nozzle; The tow delivered by the nozzle; the treatment unit having a rotatable treatment drum with a rotating drum wall for guiding and tempering the stuffing produced by the stuffer box regulation. Background technique [0002] When crimped filaments are produced in the melt spinning process, the crimp of the filaments is caused by stuffing the tow into a filament plug. In this known process, due to the stuffing of the tow, the monofilaments are laid in loops and arcs and compressed into a stuffing, so that after the stuffing is opened, a filament with crimped monofilaments is produced. The shape of the crimps contained in the monofilament depends essentially on the heat treatment of the filament plug. In order to be able to make the residence time for controlling the temperature of the thread ...
