Um derartige Perlfäden herzustellen, war es bisher üblich, die Fäden auf mit Löchern versehene Röhren, aus denen die Perlmasse heraustritt, herabzusenken und die Fäden in drehende Bewegung zu versetzen, so dafs die aus den Löchern heraustretenden Tropfen die Fäden umhüllten, auf denen diese Tropfen nach dem Trocknen als feste, runde Perlen festhafteten (s. D. R. P. 37116, Klasse 8).In order to produce such pearl threads, it has hitherto been customary for the threads to be provided with holes Tubes, from which the pearl mass emerges, lower down and the threads in rotating ones Movement so that the drops emerging from the holes remove the threads on which these drops adhered as solid, round pearls after drying (see D. R. P. 37116, Class 8).

Ein solches Verfahren ist
stä'ndlich und erfordert complicirte Apparate.One such procedure is
permanent and requires complicated apparatus.

Um diese Uebelstände zu vermeiden, wird gemäfs dem vorliegenden Verfahren die Perlung in der Weise ausgeführt, dafs man vorzugsweise sehr dünne und glatte Fäden durch eine Gelatinelösung derart rasch hindurchführt, dafs die Fäden von der Gelatinelösung zwar umspült, aber nicht durchdrungen werden, so dafs dieselbe an den Fäden abgleiten und sich zu Tröpfchen zusammenziehen kann, während die Fäden in den Zwischenräumen zwischen den einzelnen Tröpfchen unberührt bleiben.In order to avoid these inconveniences, the pearling is carried out according to the present procedure carried out in such a way that preferably very thin and smooth threads are passed through a gelatin solution passes through it so quickly that the gelatin solution washes around the threads, but not are penetrated, so that they slide off the threads and contract into droplets can, while the threads in the spaces between the individual droplets remain untouched.

Hierbei kann die Gelatinelösung je nach ihrer Concentration kalt oder heifs und eventuell mit Farbstoffen versetzt verwendet werden. Zweckmäfsig findet eine heifse Lösung von 2 kg Gelatine in 2 bis 7 kg Wasser Anwendung.Depending on its concentration, the gelatin solution can be cold or hot and possibly with Dyes can be used offset. A hot solution of 2 kg is useful Use gelatine in 2 to 7 kg of water.

Um ferner die gebildeten Perlen bezw. Tröpfchen unlöslich zu machen, kann man entweder die geperlten Fäden mit Kaliumbichromat, Formaldehyd u. dergl. behandeln, oder man kann der Gelatinelösung Alaun, Formaldehyd oder dergl. hinzufügen.To also bezw the formed pearls. One can either make droplets insoluble treat the pearled threads with potassium dichromate, formaldehyde and the like, or you can can add alum, formaldehyde or the like to the gelatin solution.

Falls die Fäden zwischen den Tröpfchen durch die zum Färben der Gelatine angewendete Farbe verunreinigt sein sollten, kann man sie reinigen, indem man sie 5 bis 10 Minuten lang oder je nach Bedürfnifs kürzere oder längere Zeit in eine Lösung von Natriumsulfit oder hydroschwefligsaurem Natrium taucht und darauf mit Wasser abspült.If the threads between the droplets through the used to color the gelatin Should paint be contaminated, it can be cleaned by leaving it for 5 to 10 minutes in a solution of sodium sulfite or for a longer or shorter period of time, depending on the needs Sodium hydrosulphurous acid is immersed and then rinsed off with water.

Das Verfahren möge nun zum besseren Verständnifs an Hand der Zeichnungen des hierfür verwendeten Apparates beschrieben werden.For a better understanding, the method should now be based on the drawings of this used apparatus are described.

Fig. ι a zeigt eine Seitenansicht, zum Theil im Querschnitt, Fig. 1 b eine Oberansicht eines Apparates, mittels dessen es gelingt, eine grofse Anzahl Fäden auf einmal zu perlen, α ist ein Gestell, auf welches man eine gewisse Anzahl von Spulen legen kann, so wie es z. B. zum Ausbreiten des zum Weben bestimmten Zettels geschieht.Fig. Ι a shows a side view, partly in cross section, Fig. 1b shows a top view of an apparatus by means of which it is possible to bubble a great number of threads at a time, α is a frame upon which to place a certain number of coils can, as it z. B. happens to spread the slip intended for weaving.

Die Fäden b werden zwischen den Zähnen eines Kammes c geführt, welche so vertheilt sind, dafs sich die Fäden b den Löchern d des Behälters e gegenüber befinden; die Fäden könnten auch direct von den Spulen in die Löcher geführt werden, jedoch erhalten sie durch den Kamm eine bessere Lage, so dafs man genauer das Abhaspeln der Fäden beobachten und sich leichter dem Gestell α nähern kann, e ist ein Gefäfs, welches die Gelatinelösung enthält, welche in diesem Behälter beständig in gleicher Höhe gehalten wird. Dies wird dadurch bewirkt, dafs man die mit der Gelatinelösung gefüllte Flasche^/ umkehrt und Sorge trägt, sie über dem Gefäfs e in gröfserer oder geringerer Ent-The threads b are guided between the teeth of a comb c , which are so distributed that the threads b are opposite the holes d of the container e; the threads could also be led directly from the bobbins into the holes, but the comb gives them a better position, so that one can more closely observe the unwinding of the threads and more easily approach the frame α , e is a vessel which holds the gelatin solution contains, which is constantly kept at the same level in this container. This is achieved by turning the bottle filled with the gelatin solution upside down and taking care to place it over the vessel in a larger or smaller area.

Claims

to keep floating away from its bottom, depending on whether a greater or lesser height of the liquid layer in the vessel is desired. The bottle is expediently held at the desired height by means of the lid g , which has just a sufficiently large opening to allow the neck of the bottle f to pass through, whereby the knee-shaped bent part h on the lid g receives its support point around the bottle to hold over the vessel. Instead of an opening, several round openings can be made in order to use several bottles, whereby the distribution of the solution can be regulated even better.

The container e and the bottle / can also consist of a container with double walls, which has a funnel for filling hot water.

On the lower side of the container e, where the holes d allow the threads b to pass through the solution, a rubber sheet i or the like is attached, which is also provided with holes which are slightly smaller than the corresponding holes d and the purpose have to allow the filaments to enter the container without having to fear that the liquid will escape through the holes d.

The part k, which is at the front of the container, is bevelled slightly so that the threads can be easily pulled through the liquid without suffering too much friction on the edge Z, in which the thread is scraped on one side, whereby it is possible to regulate the distribution of the liquid. The filaments b gefafst and at its exit from the container e by means of a clamp or the like. (Fig. 2) ρ mounted on the reel to keep it in exactly the distance that they ρ BEZW on the reel. to take on the bars m (see Fig. 1 a). If the reel is set in rotation, the threads are pulled through the solution, and since this does not have time to adhere firmly to the threads, it separates and forms droplets which, depending on the composition of the solution, can have different shapes; in general, however, they almost all show a round shape, which is more or less flattened, and, depending on the substance used, surround the threads or adhere to one side of them.

The winding of the thus treated, now beaded threads is done in such a way that when the reel ρ is turned from a second reel ν (Fig. 1 a and 1 b) strips roll up, which on two parallel bands η ο by means of pieces of wood r or the like . that are attached to the bands η ο at certain intervals. These strips m must not be higher than half the height of the pieces of wood. Desired case, these do something can be made lower, so that the same is formed a sufficient free space between the individual plies during the winding; so that the filaments, which obtain during winding onto the last m hold, to be about upcoming frames in can not touch.

W ^r hen the reel ρ is full, it accepts a clamp on the type of the drawn in Fig. 2, fastens the threads at this terminal, as is done initially when one conceives as they exit from the vessel, e to make them exactly in the distance they occupy on the reel ρ , and then dry in the open air or in a warm room, depending on the composition of the solution.

So that the pearled threads do not adhere to the rods m , it is expedient to grease the rods in a suitable manner.

While the pearled threads are drying on the reel ρ , a second reel can be wound. When carrying out the method, the reel v is expediently used to wind up the tapes η ο with the strips in, and the reel p to take up the pearled threads as they come out of the container e .

The reel v. and ρ are shown during operation in order to explain the unwinding of the ribbons η ο and the winding up of the pearled threads.

Fig. Ι c shows a beaded thread reel n> at the moment when the pearled threads roll up on two other reels χ j.

To carry out this operation, the threads are passed between the teeth of a rake s and between the teeth of the rake t ^, which are located in front of the reels χ j .

The pearled threads can also, as soon as they come from the reels ρ and w , be wound onto a star wheel, which is set up as indicated in Fig. 3, in that the threads, without touching each other, on insertable and removable cross rods u (Fig . 4) are rolled up, which are inserted into the column s of the cross armsj ^ j / - according to the measure of the winding. This star wheel, when fully wrapped, can be immersed in a bath for insolubilization, bleaching, dyeing, or simply washing, if necessary.
