 flüssigkeit wird in den unterhalb der unteren Tragscheibe befindlichen Wannen 10 aufgefangen, aus denen sie mittels Pumpen abgesaugt und nach erfolgter Regenerierung wieder der Berieselungsvorrichtung 9 zugeführt werden kann. 



   Die Länge des Trag-und Führungsbandes 5 bzw. die Zahl und Entfernung der Treibscheiben- paare werden so bemessen, dass bei gegebener Spinngeschwindigkeit (z. B. 70 m/min.) das Spinngut über die zur Nachbehandlung erforderliche Zeit auf dem Bande verbleibt. 



   Die Scheibenpaare können entweder so wie in der Zeichnung dargestellt, gleichachsig auf zwei parallelen Wellen untereinander angeordnet sein, die senkrecht zur Länge des Fällbadtroges stehen. 



   Es können auch, falls z. B. ausschliesslich eine einfache Entsäuerung des Spinngutes   gewünscht   wird, die Achsen der Scheiben parallel zum Fällbadtrog angeordnet werden oder aber andere Anordnungen   der Scheiben (z. B. auf mehreren nebeneinanderliegenden Wellen usw. ) zur Anwendung gelangen.  
Das von der letzten Scheibe ablaufende Trum wird über ein Leitrollensystem 11 abgelenkt und über ein zweites System 12 der ersten oberen Scheibe wieder zugeführt. Die infolge der verschiedenen
Umfangsgeschwindigkeiten innerhalb des endlosen Tragbandes 5 auftretenden ungleichen Seil- spannungen können sich auf dem Wege über die Leitrollen ausgleichen, wobei unter Umständen vorteil- hafterweise angetriebene Rollenpaare Verwendung finden können. 



   Je nach Zahl der vorhandenen Tragscheiben 6,6'bzw. nach der Länge des Tragbandes kann eine beliebige Zahl von Behandlungsbädern hintereinander geschaltet werden. So ist die Reihenfolge der Bäder z. B. folgende :   Wasser -. Schwefelnatrium--Wasser-Salzsäure-Wasser-CNor-Wasser   und zuletzt als Avivierbad z. B.   Türkisehrot.   



   Nach Passieren des Avivierbades wird das nasse-Spinngut von dem Tragband 5 abgenommen und gegebenenfalls durch Quetschwalzenpaare   13 hindurchgeführt,   die   die'überflüssige Feuchtigkeit   abquetschen. Nach Passieren des Quetsehwalzenpaares wird das Spinngut von einer weiteren Transport-   vorrichtung 14, z. B. einem endlosen. Transportgurt aufgenommen, . der es durch eine Troekenzone 15,   z. B. einen mit. Heissluft bestrichenen Raum hindurchführt. Hierauf gelangt das Spinngut in eine
Aufspulvorrichtung 16, die-auch als Zwirnmaschine ausgeführt werden kann.

 <Desc / Clms Page number 2>

 Liquid is collected in the troughs 10 located below the lower support disk, from which it can be sucked off by means of pumps and fed back to the sprinkling device 9 after regeneration has taken place.



   The length of the support and guide belt 5 or the number and distance of the pairs of traction sheaves are dimensioned in such a way that at a given spinning speed (e.g. 70 m / min.) The spun material remains on the belt for the time required for post-treatment.



   The pairs of disks can either be arranged coaxially on two parallel shafts one below the other, as shown in the drawing, which are perpendicular to the length of the felling bath trough.



   It can also, if z. B. only a simple deacidification of the spinning material is desired, the axes of the disks are arranged parallel to the felling bath trough or other arrangements of the disks (e.g. on several adjacent shafts etc.) are used.
The run running from the last disc is deflected by a guide roller system 11 and fed back to the first upper disc via a second system 12. The result of the various
Unequal rope tensions occurring at circumferential speeds within the endless carrier belt 5 can be equalized on the way over the guide rollers, it being possible, under certain circumstances, to advantageously use driven roller pairs.



   Depending on the number of supporting disks 6,6 'or Any number of treatment baths can be connected in series depending on the length of the carrier tape. So the order of the baths is z. B. the following: water -. Sulfur sodium - water-hydrochloric acid-water-CNor-water and finally as a finishing bath z. B. turquoise red.



   After passing through the softening bath, the wet spun material is removed from the carrier belt 5 and, if necessary, passed through pairs of squeezing rollers 13 which squeeze off the excess moisture. After passing the pair of squeeze rollers, the spun material is transported by a further transport device 14, e.g. B. an endless one. Transport belt added,. which it through a dry zone 15, z. B. one with. Hot air coated room passes through. The spun material then passes into a
Winding device 16, which can also be designed as a twisting machine.

PATENT-ANSPRUCH : Vorrichtung zur Behandlung von. Fäden, Bändchen od. dgl. aus Zellulose oder deren Derivaten aus. einem über Trag-und Antriebsrollen laufenden endlosen Band ; das als Führungs-und Tragorgan für'das aus dem Fällbad austretende Spinnprodukt dient, dadurch gekennzeichnet, dass die Umfangs- geschwindigkeit der das Band tragenden aufeinanderfolgenden Scheibenpaare (6, 6') entsprechend - der Längenänderung des Spinngutes während-der Nachbehandlung sich ändert, wobei das Band (5) aus. elastischem Werkstoff besteht und die Unterschiede in der Laufgeschwindigkeit durch Änderung der inneren'Spannung ausgleicht. PATENT CLAIM: Device for the treatment of. Threads, ribbons or the like made of cellulose or its derivatives. an endless belt running over support and drive rollers; which serves as a guide and support element for the spun product emerging from the precipitation bath, characterized in that the circumferential speed of the successive pairs of disks (6, 6 ') carrying the strip changes according to the change in length of the spinning material during the aftertreatment, whereby the tape (5). elastic material and compensates for the differences in running speed by changing the internal tension.
