PATENTAMT.PATENT OFFICE.

In vielen Fällen macht sich das Bedürfnis geltend, die bekannten Vorrichtungen zum Färben usw. von Obermaier (vergl. Patentschrift 23 117) und alle auf der gleichen Wirkungsweise beruhenden Vorrichtungen in der Weise benutzen zu können, daß die Durchdringung des zu färbenden Materials nicht nur in einer Richtung, z. B. von innen nach außen (Fig. 1), sondern auch von der anderen Richtung, also von außen nach innen (Fig. 3), erfolgt. In many cases, the need arises to use the known devices for Dyeing, etc. from Obermaier (see patent specification 23 117) and all on the same mode of action based devices to be able to use in such a way that the penetration of the material to be colored not only in one direction, e.g. B. from the inside to the outside (Fig. 1), but also from the other direction, so from the outside to the inside (Fig. 3) takes place.

Mit den bekannten Materialträgern läßt sich dies nicht gut erreichen, da ja die Summe der Querschnitte der Lochungen des äußeren Mantels b (Fig. 3) kleiner ist als bei dem inneren Mantel a, und infolgedessen beim Arbeiten nach Fig. 2, d. h. wenn die Pumpe saugt, nicht so viel Flüssigkeit durch die Lochungen von b (Fig. 3) nachströmen kann, als von der Pumpe am inneren Mantel a (Fig. 3) weggenommen wird. Ein Druck wird also im Zwischenraum zwischen den Mänteln α und b nicht entstehen, und zwar weder durch Drücken von außen nach innen, noch beim Saugen von außen nach innen. Besonders im letzteren Falle wird sich durch den Unterschied zwischen der durch die Pumpe weggenommenen und der nachströmenden Flüssigkeit ein sogenannter Trichter bilden (Fig. 3, Dreieck c-d-ej, so daß ι. nicht die ganze Beschickung des Materialträ'gers von der Flotte berührt wird, 2. eventuell Luft statt Flüssigkeit gesaugt wird. Beides sind große Übelstände, die den normalen Fa'rbevorgang in Frage stellen.This cannot be easily achieved with the known material carriers, since the sum of the cross sections of the perforations of the outer shell b (FIG. 3) is smaller than that of the inner shell a, and consequently when working according to FIG. 2, ie when the pump sucks, not so much liquid can flow through the holes in b (Fig. 3) than is removed from the pump on the inner jacket a (Fig. 3). A pressure will therefore not arise in the space between the jackets α and b , neither by pressing from the outside in, nor when sucking from the outside in. Especially in the latter case, a so-called funnel will form due to the difference between the liquid removed by the pump and the liquid flowing in afterwards (Fig. 3, triangle cd-ej, so that the entire charge of the material carrier is not affected by the liquor 2. Air instead of liquid may be sucked in. Both of these are major inconveniences that call the normal coloring process into question.

Um nun beim Bruch der Flotte nach zwei Richtungen die gleiche Wirkung zu erzielen, muß der Materialträger so gestaltet sein, daß beim Färben sowohl in der Richtung der Pfeile in Fig. ι als auch in der Richtung der Pfeile in Fig. 2 die Summe der Querschnitte der Lochungen an der Eintrittsstelle der Flüssigkeit größer ist als an der Austrittsstelle.In order to achieve the same effect when the fleet breaks in two directions, the material carrier must be designed in such a way that when dyeing both in the direction of the Arrows in Fig. Ι and in the direction of the arrows in Fig. 2, the sum of the cross-sections the perforations at the entry point of the liquid is larger than at the exit point.

Dies wird durch die nachstehend beschriebene, den Gegenstand der vorliegenden Erfindung bildende Vorrichtung erreicht.This becomes the subject matter of the present invention as described below forming device achieved.

Der neue Materialträger (Fig. 4) besteht nicht, wie bisher, aus zwei gelochten Mänteln α und b, deren innerer Zwischenraum zur Aufnahme der Ware dient, sondern aus drei gelochten Mänteln α, b und g, bei dem die Summe der Querschnitte der Lochungen von Mantel a größer ist als die von Mantel g, aber kleiner als von Mantel b. Der Raum zwischen α und b dient ebenso, wie bisher, zur Aufnahme des Materials, der zwischen b und g befindliche Raum bleibt frei, ist jedoch oben und unten geschlossen. Zylindermantel α ist mit großen Löchern von etwa 4 bis 6 mm Durchmesser gelocht (Fig. 6), Zylindermantel b desgleichen, Zylindermantel g ist fein gelocht, in gleichen Abständen wie α und b, jedoch Löcher von etwa ι mm Durchmesser (Fig. 7). Falls andere Lochungen in Anwendung gelangen, so müssen diese in entsprechenden Verhältnissen stehen.The new material carrier (Fig. 4) does not, as before, consist of two perforated shells α and b, the inner space of which is used to accommodate the goods, but of three perforated shells α, b and g, in which the sum of the cross-sections of the perforations of coat a is larger than that of coat g, but smaller than that of coat b. As before, the space between α and b serves to accommodate the material; the space between b and g remains free, but is closed at the top and bottom. Cylinder jacket α is perforated with large holes of about 4 to 6 mm in diameter (Fig. 6), cylinder jacket b is the same, cylinder jacket g is finely perforated, at the same intervals as α and b, but holes of about ι mm in diameter (Fig. 7) . If other perforations are used, these must be in the appropriate proportions.

Im Zylindermantel g befinden sich auf mehreren Seiten Ausschnitte in unbestimmter Anzahl und Größe (je nach der Größe der Materialträger), die mittels Deckel oder Schieber h geöffnet und geschlossen werden können. Die Deckel h können sich zweckmäßig nach innen in dem Raum zwischen b und g öffnen. Die Öffnungen, welche durch die Deckel h ge-In the cylinder jacket g there are cutouts in an indefinite number and size (depending on the size of the material carrier) on several sides, which can be opened and closed by means of a cover or slider h. The lids h can expediently open inwards in the space between b and g. The openings through the cover h

Claims

are closed, must be so large and so numerous that they allow more liquid to enter the space b and g than is removed, i.e. the sum of the cross-sections of the openings closed by cover h and the perforations in jacket g must be the same or greater than the sum of the cross-sections of the perforations of jacket b . The closing and opening of the lids

xo or slide h can be carried out automatically in connection with the change in the liquor flow.

Working with the device described and shown in FIG. 4 now takes place as follows:

If the liquid is moved in the direction according to FIG. 1, the covers h are closed. The liquor enters the goods through the perforations in the shell α , passes through the same, passes through the perforations in the shell b into the space bg and exits through the perforations in the shell g . The voltage of the liquor flow is present because the sum of the cross-sections of jacket α is greater than that of jacket g. If the work is done in the direction shown in FIG. 2, the covers h are opened or open automatically. The liquor flows into the space bg, passes through the perforations in the jacket b into the material space between α and b, passes through the goods and exits through the perforations in the cylinder a. Again, the voltage of the liquor flow is established, provided that it is pressed, on the other hand prevents the formation of a funnel during suction, since the jacket g is switched off and only the two jackets α and b come into action. The sum of the cross-sections of jacket b (Fig. 4) is greater than that of jacket a.

The principle of overpressure for both fleet runners will apply not only to cylinders, but also to devices in which one must think of the cylinder as cut open and the jackets α, b and g (Fig. 4) then straight walls a, b and c (Fig. 5), in which the sum of the cross-sections of α is greater than that of c, and that of b is greater than that of a, due to the corresponding perforations. The material is in the space between a and b, the wall c has the closable openings. If the current goes in the direction of the arrow m, the flaps are closed and open in the direction of the arrow η.
