Unter Entwicklungs- oder Kupplungsfarben versteht man seit einigen Jahren die auf Faserstoffen erzeugten Azofarben, wie beispielsweise den aus ß-Napthol und diazotirtem p-Nitranilin erzeugten rothen Farbstoff. Diese Farbstoffe konnten bisher nur zum Drucken von Kattun verwendet werden, während es als unmöglich galt, Zeuge in Stücken damit in rationeller Weise zu färben: Das Verfahren mufs nämlich derartig ausgeführt werden, dafs die beispielsweise mit ß-Naphtol imprägnirten und getrockneten Gewebe durch- eine Paranitrodiazobenzolchloridlösung geführt werden; hierbei ist aber die technische Schwierigkeit zu überwinden, die durch die sehr schnelle Zersetzbarkeit der Diazolösung bedingt wird, zumal es besonders für schwerere, dickere Waare nothwendig ist, dafs diese leicht zersetzliche Lösung eine ziemlich lange Zeit mit dem zu färbenden Stoffe in Berührung bleibt. Diese beiden Schwierigkeiten umgeht Erfinder dadurch, dafs er ganz kleine Farbbehälter anwendet und das Zeug so führt, dafs es einen verhältnifsmäfsig grofsen Weg in dem Behälter beschreibt, gleichzeitig aber kein Ausquetschen der Lösung vornimmt, sondern das Gewebe direct aus diesem Behälter aufwindet.For some years now, development or coupling colors have been understood to mean those on fibers generated azo colors, such as those from β-napthol and diazotized p-nitroaniline produced red dye. Until now, these dyes could only be used to print calico used while it was considered impossible to witness in pieces so in more rational way How to color: The method must namely be carried out in such a way that the, for example tissue impregnated with β-naphthol and dried through a solution of paranitrodiazobenzene chloride be led; here, however, the technical difficulty has to be overcome, which is caused by the very rapid decomposability the diazo solution, especially since it is necessary especially for heavier, thicker goods that these easily decompose Solution remains in contact with the fabric to be dyed for a fairly long time. Inventors circumvents both of these difficulties by using very small paint containers and the stuff goes in such a way that there is a comparatively large path in the container describes, but at the same time does not squeeze out the solution, but rather the tissue winds up directly from this container.

Hierdurch wird erreicht, dafs das Zeug alle benutzte Flüssigkeit mitreifst, welche durch ein Zuleitungsrohr continuirlich, und frisch bereitet, ersetzt wird. Ferner wird erreicht, dafs die Waare eine längere Zeit der Diazoflüssigkeit ausgesetzt wird, wodurch die Verbindung derselben mit dem Naphtol —- allgemein Entwickler — auf der aufgewickelten Walze vollständig erzielt wird. Hierzu ist aber ein besonderer, von den bisherigen Aufwindemechanismen für das aus der Flotte kommende Zeug abweichender Mechanismus nothwendig, da die bisherigen Mechanismen dieser Art, welche die Aufgabe zu lösen haben, trotz des allmäligen Dickerwerdens der Zeugwalze eine gleichmäfsige Lineargeschwindigkeit des Zeuges zu erreichen, nicht genügen. Preis- und Ausquetschwalzen müssen aberj wie Erfinder festgestellt hat, unter allen Umständen vermieden werden, da die Diazolösung wegen der, wie eingangs erwähnt, durch ihre leichte Zersetzbarkeit nothwendig werdenden raschen Durchführgeschwindigkeit des Zeuges an und für sich nur gering an dem Zeuge haftet.In this way it is achieved that the stuff ripens along with all the used liquid which passes through a supply pipe is continuously, and freshly prepared, replaced. It is also achieved that the goods are exposed to the diazo liquid for a longer period of time, which results in the connection of the same with the naphthol - generally developer - on the wound roller completely is achieved. For this, however, there is a special one from the previous winding mechanisms a different mechanism is necessary for the stuff coming out of the fleet, since the previous mechanisms of this type, who have to solve the task, despite the gradual thickening of the stuff roller Achieving a constant linear speed of the stuff is not enough. Price and squeeze rollers but must be determined as inventor has to be avoided under all circumstances, since the diazo solution because, as mentioned at the beginning, by its easy decomposability necessary rapid execution speed of the stuff on and for adheres only slightly to the witness.

Nach dem bisher Gesagten ergiebt sich nun die Lösung der gestellten Aufgabe in der gleichzeitigen Verwendung kleiner · Flottenbehälter, in welchen das Zeug einen grofsen Weg beschreibt und die Flotte der Mitnahme durch die Waare entsprechend beständig ersetzt wird, und einer dem allmäligen Dickerwerden der Zeugwalze Rechnung tragenden Durchziehvorrichtung, welche kein Ausquetschen des Zeuges bewirkt.According to what has been said so far, the solution to the task at hand now results in the simultaneous use of small liquor containers in which the stuff a big one Describes the route and replaces the fleet with the goods accordingly consistently and a pull-through device that takes into account the gradual thickening of the stuffing roller, which does not cause the stuff to be squeezed out.

Eine Maschine dieser Art ist in beiliegender Zeichnung dargestellt; Fig. 1 ist eine Oberansicht und Fig. 2 ein Verticalschnitt.A machine of this type is shown in the accompanying drawing; Fig. 1 is a top view and FIG. 2 is a vertical section.

D ist ein hoher, schmaler Farbbehälter mit verbreiterten oberen Rändern D¹. Am Boden des Behälters befindet sich eine Führungswalze C und das Zeug Z nimmt seinen Weg über die Führungswalzen BLCL¹ auf die Zeugwalze A, auf welche es, ohne Ausquetschwalzen zu passiren, aufgewickelt wird. Die Flotte steht in dem Behälter bis zur D is a tall, narrow paint container with widened upper edges D ¹ . At the bottom of the container there is a guide roller C and the stuff Z takes its way over the guide rollers BLCL ¹ to the stuff roller A , on which it is wound without passing squeezing rollers. The liquor is in the container up to

Claims

Line NN and is continuously replaced by a side feed pipe to the extent that it is carried along by the stuff. It is clear that with this arrangement there is only very little liquid in the container D and that freshly prepared or not yet decomposed colored liquid is thus always presented to the following items.

In this way one is able to obtain the same always pure color shade not only for the beginning, but also for the whole of the goods wound on A. Since the ware is not squeezed off after leaving the dye bath, but rolls up onto A , no used and thereby decomposed liquid flows back into the container and every part of the ware takes with it the mechanically loosely adhering precipitate. The container need not be exactly parallelopipedal; he could e.g. B. beveled at the bottom by corners or, following the shape of the roller C , be semi-cylindrical at the bottom.

The roller A is driven by means of a pulley R or a toothed wheel, which are connected to a back gear with a variable number of revolutions, so that it is possible to maintain the peripheral speed of the goods winding on A within set limits. This can be done by associating A with two or more pulleys of different diameters, which are used either automatically or sequentially by the worker operating the machine. This purpose is most perfectly achieved as follows.

The roller A is connected by a pulley R to the back gear V , which is moved by the drive shaft W through a cone. The cable fork E can be adjusted from F to H by means of the threaded rod G, so that from V to W with a number of revolutions of, for example, 2: 5, it can gradually be reduced to a number of 5: 2. This change in position of the fork E is achieved by connecting the rotatable threaded rod G to the roller A through chain and gear transmission. By rotating the roller A , the gear Z sitting on the same gives the gear Z ⁶ a number of revolutions that is reduced, for example, six times; The latter is rigidly connected to the chain wheel K , which by means of a chain sets the chain wheel 5 seated on G in rotation. Therefore, when winding Stückwaare on A which erfahrungsgemäfs requires more than 600 revolutions of A, experienced Z ⁶ and hence K and S is a 100 times rotation, and since the threaded rod G 100 counts screw threads, thereby the guide fork E from H to F brought, whereby the number of revolutions of A is reduced in the ratio of 25: 4; Since the diameter of the winding on A has meanwhile increased in the ratio of 4:25, a constant peripheral speed has been reached, and thus the action of the continuously renewing dye liquor on the fiber is given a constant period of time. By unwinding the stuff from A, for example mechanically, the fork E is of course returned to its previous position; the machine is therefore easily ready to accept a new batch.

Patεντ-A ν saying:

A piece dyeing machine for the use of so-called developing colors (azo colors), in which to keep the dye liquor clean (solution of the diazo body), as well as to achieve it more intense and even coloring the primed ware spread out from the Paint container directly (without passing the squeezing rollers) after that from the axis driven winding roller. whose circumferential speed is constant by means of an automatic reduction in the angular speed is obtained.
