Definitions
- the invention is based on a method for producing stretched and fixed monofilaments in a thread strand, which comes from a spinning head, a cooling system. pass through a drying system, a stretching device and a fixing section up to a winding device.
- the group of threads passes through a first stretching unit with four or five stretching rollers after drying. This has the advantage that the thread group can be threaded faster and more easily. The thread run is easier to monitor and control devices for continuous monitoring of the thread thickness and thread tension can be installed more clearly.
- the method according to the invention thus meets all of the expanded requirements which are necessary in order to be able to produce high-quality monofilaments over short distances with high throughput rates.
- Only the convection dryers known from the publication DE-OS 39 09 173 AI are used as hot air units, hot air dryers and for fixing and formulation, which can be assembled into units of any size.
- FIG. 2 shows a system section with which, according to the invention, pre-stretching can be carried out using the method according to the invention
- the hot air dryer 13 has a flap 21 which can be swiveled forward and which opens for introducing the thread sheet 11 have to be.
- the thread group 11 is. in the hot air dryer 13 with. shown by a dashed line.
- the thread sheet 11 is fed to a first stretching roller 22, which deflects the thread sheet 11 by 180 ° and feeds a second stretching roller 23.
- the second stretching roller 23 also deflects the thread sheet 11 by 180 ° and feeds the thread sheet 11 to a third stretching roller 24, which likewise feeds the thread sheet 11 to a fourth stretching roller 25 with a deflection of 180 °.
- the yarn sheet is stretched vorge 57, that is, the drawing roll peripheral speed of the stretching rolls 59 must be greater than the Reckwalzen- peripheral speed of the stretching rolls 58 of stretching the work 52.
- the yarn sheet 57 takes in the stretching unit 54 has a yarn path 57 1 v .
- the stretching units 52, 54 are only equipped with four stretching rollers 58, 59, because they are for pre-stretching the thread family 57 in the pre-stretching stage 55 lower tensile forces occur.
- the stretcher 52 is provided with a suction device 60 which detects and sucks thread breaks. The construction and mode of operation of the suction device 60 corresponds to the suction devices already described.
- the preparation device 68 enables a formulation aid 68 'to be sprayed onto the thread sheet 71 as a separate device.
- Components of the formulation aid 68' are dried in the dryer 69 so that monofilaments are present in the wound form which have a desired dried coating.
