Bei dieser bekannten Vorrichtung (britische Pa- 55 Weise in einer geradlinigen, senkrecht zur Zeichententschrift 487 648), die auch zum Herstellen von ebene sich erstreckenden Reihe eine Vielzahl (z. B. Wirrvliesen aus Glasfaden Verwendung findet, ist die mehr als 100) von Spinnöffnungen 7 auf, von denen den Luftstrom zum Verstrecken der Fadenschar füh- jede einen Durchmesser von etwa 0,4 mm hat.

Diese Wirkung des Luft- unterhalb den Längsdüsen 1, 2, 3, 4 angeordneten stromes wird noch dadurch verstärkt, daß der unter- Kanäle 10, 11, 12, 13 führt. Jeder Kanal 10, 11, 12, halb der Flachdüse angeordnete Luftführungskanal 13 ist mit einer oberen Luftkammer 14 und einer un-In this known device (British Pa- 55 way in a straight line, perpendicular to the characters 487 648), which can also be used to create flat, extending rows (e.g. Random nonwovens made of glass thread is used, the more than 100) of spinning orifices 7 of which the air flow for stretching the thread sheet each has a diameter of about 0.4 mm. Of the The resulting flat nozzle is therefore at a pronounced distance from one another to a spinning nozzle stood below the spinning orifices, around 60 associated spinning orifices is 2 mm. On both to generate an air flow, the sides of which are essentially the longitudinal nozzle openings 7, each with a straight air core of oscillating air flow slot 8 with an opening width of approximately 0.3 mm is superimposed so that the spun threads net. The air slots 8 through the chambers 9 In addition to stretching, hot air is often fed in, which flows out of the spinning orifices 7 wound and possibly other threads are captured 65 escaping spun material and with this in the should be given form. This effect of the air arranged below the longitudinal nozzles 1, 2, 3, 4 Stromes is reinforced by the fact that the sub-channels 10, 11, 12, 13 leads. Each channel 10, 11, 12, half of the flat nozzle arranged air duct 13 is with an upper air chamber 14 and an un-

teren Luftkammer 15 ausgestattet, durch welche zusätzliche Luft in der Kanallüngsrichtung zugeführt wird. Innerhalb der Kammern 10, 11, 12, 13 wird infolge der Wirkung der bei 9, 14, 15 eintretenden Luftströme eine Verstreckwiikung auf das mit 16 bezeichnete Fadenmaterial ausgeübt. Das Fadenmaterial 16 wird auf dem Auffangband6 in Form eines Wirrfadenvlieses 17 abgelegt. Zur Verbesserung der Fadenablage wird unterhalb des Auffangbandes 6 bei 18 in bekannter Weise (vgl. USA.-Patentschrift 3 040 412) die Luft abgesaugt.Direct air chamber 15 equipped, through which additional air is supplied in the Kanallüngsrichtung will. Inside the chambers 10, 11, 12, 13 is due to the action of 9, 14, 15 occurring Air currents exerted a stretching effect on the thread material denoted by 16. The thread material 16 is deposited on the collecting belt 6 in the form of a tangled fleece 17. To improve the Thread deposit is below the collecting belt 6 at 18 in a known manner (see. USA. Patent 3 040 412) sucked out the air.

Der gegenseitige Abstand der Luftdüsen 1, 2, 3, 4 beträgt mindestens 60 mm, um eine saubere Trennung der Spinngutscharen zu gewährleisten. Die obere Kante der flachen Luftkanäle 10, 11, 12, 12 soll von den zugehörigen Öffnungen 7 zur Erzielung einer exakten Fadenführung nicht mehr als 20 mm entfernt sein.The mutual distance between the air nozzles 1, 2, 3, 4 is at least 60 mm to ensure a clean separation to ensure the spinning shares. The top edge of the flat air ducts 10, 11, 12, 12 should not more than 20 mm from the associated openings 7 to achieve an exact thread guide be distant.

Die Breitflächen jedes Luftkanals 10, 11, 12, 13The broad areas of each air duct 10, 11, 12, 13

weisen einen gegenseitigen Abstand von etwa 10 mm auf.have a mutual distance of about 10 mm.

Die Temperatur der Spinndüsen und der in der Vorrichtung eingesetzten Luftströme ist entsprechend den Materialeigenschaften des zu verspinnenden Polymeren zu bemessen. Die Geschwindigkeit der Luftströme ist so einzustellen, daß die Luftgeschwindigkeit im Bereich der Luftschlitze 8 mindestens die fünffache Geschwindigkeit des Spinngutes beim Austritt aus den Spinnöffnungen 7 beträgt.The temperature of the spinnerets and the air currents used in the device is appropriate to measure the material properties of the polymer to be spun. The speed the air flow is to be adjusted so that the air speed in the area of the air slots 8 is at least is five times the speed of the spinning material when it emerges from the spinning orifices 7.

Wahlweise kann den Luftkanälen 10, 11, 12, 13 eine oszillierende Bewegung im Sinne der Pfeile 19 erteilt werden.Optionally, the air ducts 10, 11, 12, 13 can have an oscillating movement in the direction of the arrows 19 be granted.

Im Falle der Verarbeitung von weniger klebrigen Polymeren kann auf die Verwendung von zusätzlicher Luft in den Kammern 14 und 15 verzichtet werden. In the case of processing less sticky polymers, the use of additional Air in the chambers 14 and 15 can be dispensed with.
