Problems solved by technology

However, these optical inspection systems have only limited use possibilities, since the curling environment causes rapid soiling due to high temperatures and a large number of flying particles such as residual finishing agents and color particles
Optical systems have proven to be completely unsuitable for reliable operation in a stuffer box environment

Embodiment Construction

[0030] exist figure 1 A first embodiment of the device according to the invention is schematically shown in a cross-sectional view in FIG. The device has a delivery nozzle 1 comprising a vertically extending filament channel 3 . The filament channel 3 extends from a filament inlet 7 on the top side of the delivery nozzle 1 to a filament outlet 6 on the bottom side of the delivery nozzle 1 . A plurality of compressed air channels 4 open into the thread channel in the upper region of the delivery nozzle 1 and connect the thread channel to a compressed air source 5 . Further components, not shown here, are provided between delivery nozzle 1 and compressed air source 5 for conducting and processing the compressed air. It is common, for example, to heat the compressed air before entering the filament channel 3 .

[0031] Directly adjoining the underside of the delivery nozzle 1 is a stuffer box 2 , which is delimited by a gas-permeable box wall 8 and held within the suction chambe...

Abstract

A method and a device for crimping a multifilament thread are described. The thread is blown by means of a transport nozzle through a compressed air stream guided in a thread channel into a gas-permeable compression chamber. Inside the compression chamber, the thread is compressed to form a thread plug, which is then continuously removed through an outlet of the compression chamber. The compression and the removal of the thread plug are monitored by measuring the pressure of the compressed air stream. According to the invention, a plurality of pressures of the compressed air stream in the compression chamber are measured at a plurality of measurement points distributed over the length of the compression chamber for monitoring the thread plug formation in order to perform the compressing and cooling of the thread plug with a uniform filling of the compression chamber.

Description

technical field [0001] The invention relates to a method for texturing of multifilament filaments, in which method the filaments are blown by means of a stream of compressed air guided in the filament channel into a gas-permeable stuffer box, inside which the long The filaments are stuffed into thread plugs which are continuously discharged through the stuffer box outlet and opened into crimped filaments, the plugging and discharge of which are monitored by means of pressure measurements of the compressed air stream. The invention also relates to a device for crimping multi-filament filaments, which has a delivery nozzle connected via a filament channel to a compressed air source for generating a compressed air flow; a gas-permeable stuffing box, The stuffing box is assigned with a stuffing box inlet to a delivery nozzle for receiving a compressed air flow; a monitoring device having at least one pressure sensor for measuring the pressure of the compressed air flow. Backgrou...
