PATENTAMT.PATENT OFFICE.

Das bisher gebräuchliche Verfahren der Reinigung von Gespinnstfasern, sei es im Zustande als Flocke, Garn oder Gewebe, besteht nach Angabe des Erfinders im wesentlichen aus der Entschlichtung in einem Säurebade, Auspressung, Trocknung in mehr oder weniger erhöhter Temperatur, Entfernung der Säure durch ein oder mehrere Bäder und schliefslich abermaliger Trocknung. Eine sechste Bearbeitung, welche aber nicht immer anwendbar ist, findet nach der ersten oder zweiten Trocknung statt und bezweckt eine Absonderung der staubförmigen vegetabilischen Unreinigkeiten durch Reiben mit oder ohne Schlag.The previously common method of cleaning staple fibers, be it in the state as a flake, yarn or fabric, according to the inventor essentially consists of the Desizing in an acid bath, pressing, drying at a more or less elevated temperature, Removal of the acid by one or more baths and finally repeated drying. A sixth processing, which but is not always applicable, takes place after the first or second drying and aims to separate the powdery vegetable impurities by rubbing with it or without a punch.

Bearbeitet man die Gespinnstfasern als Flocke, so werden bei diesen verschiedenen Bearbeitungen die Fasern verwirrt und dementsprechend verkürzt bezw. beim Kämmen zerrissen. Zweck der Erfindung ist, die angedeuteten Uebelstände zu vermeiden, indem der zu reinigende Gespinnststoft" als Fliefs oder Band einem chemischen Procefs unterworfen wird, welcher die vegetabilischen Unreinigkeiten zerstört, ohne die Fiber· zu verwirren.If the staple fibers are processed as flakes, various processes are used in these the fibers confused and accordingly shortened BEZW. torn when combing. purpose the invention is to avoid the indicated inconveniences by using the textile to be cleaned " is subjected to a chemical process as a flief or band, which destroys the vegetable impurities without them Fiber · to confuse.

Bei der Herstellung von Kammgarn kommt der Gespinnststoff als Band vor oder nach seinem Lauf um die Kammtrommel zur Verwendung, . und hierdurch ist es ermöglicht, die verschiedenen Arbeiten der Reinigung gleichzeitig und stetig vorzunehmen. Hierzu dient die zu beschreibende Maschine, durch welche das Band gehen kann, ohne einer Störung der Lage seiner einzelnen Fibern ausgesetzt zu sein. Die Maschine ermöglicht ferner den Fortfall der wesentlichsten Handarbeit, welche namentlich in der Zuführung des Stoffes besteht, eine Arbeit, welche sich nach dem vorliegenden Verfahren selbstthätig vollzieht.In the production of worsted yarn, the roving appears as a band before or after its barrel around the comb drum for use,. and this enables the carry out various cleaning tasks simultaneously and continuously. Serves for this the machine to be written through which the tape can pass without disturbing the Able to be exposed to its individual fibers. The machine also enables the elimination of the most essential manual work, which consists in particular in the supply of the material, a work, which takes place automatically according to the present procedure.

Die Maschine setzt sich zusammen: 1. aus einem Rechen, welcher die Spulen a a a . . . trägt; 2. aus einem Trog B, welcher das Säurebad aufnimmt und mit entsprechend angebrachten Rollen versehen ist, die das Band so führen, dafs es nach Bedürfhifs einen längeren oder kürzeren Weg durch das Bad zurücklegt, während an dem Punkte, bei welchem das Band den Trog verläfst, zwei Prefsrollen C angebracht sind, die durch Druck dem Bande möglichst viel Flüssigkeit entziehen; 3. aus zwei Trockencylindern A und A¹, deren jeder aus zwei Seitenscheiben besteht, die auf eine hohle Welle von gröfserem Durchmesser aufgekeilt sind, während diese Welle zwischen ihren Seitenscheiben bei F häufig durchbohrt ist, um eine Verbindung mit dem Innern derselben herzustellen.The machine consists of: 1. A rake, which the coils aaa. . . wearing; 2. from a trough B, which receives the acid bath and is provided with appropriately attached rollers, which guide the tape in such a way that it travels a longer or shorter path through the bath as required, while at the point at which the tape reaches the trough runs, two press rollers C are attached, which extract as much liquid as possible from the band by pressure; 3. of two drying cylinders A and A ¹ , each of which consists of two side disks wedged onto a hollow shaft of larger diameter, while this shaft is often pierced between its side disks at F in order to establish a connection with the interior thereof.

Der Mantel der Cylinder ist aus parallel zur Wellenachse liegenden Leisten hergestellt, welche unter einander entsprechend weiten Abstand haben, so dafs gewissermafsen jeder Cylinder einer grofsen Garnhaspel gleicht. Das Band wird über zwei Rollen H und H¹ derartig geführt, dafs es den vollen Umfang des Cylinders durchlaufen rhufs und möglichst lange mit der trocknenden Luft in Berührung bleibt. Jeder der Cylinder ist durch ein Gehäuse umhüllt, welches in die Kammern L und Z¹ getheilt ist, die jedoch an ihren unteren Seiten unter sich in offener Verbindung stehen.The jacket of the cylinder is made of strips lying parallel to the axis of the shaft, which are spaced correspondingly wide, so that each cylinder resembles a large thread reel. The tape is guided over two rollers H and H ^{1 in} such a way that it runs through the full circumference of the cylinder and remains in contact with the drying air for as long as possible. Each of the cylinders is enveloped by a housing which is divided into chambers L and Z ¹ , which, however, are in open communication with each other on their lower sides.

Ein Trog B' enthält Wasser, welches sich durch stetigen Ab- und Zuflufs erneut. Ein zweiter Trog B" enthält ein irgendwie zusammengesetztes basisches Bad (Auflösung von SodaA trough B ' contains water, which is renewed by constant outflow and inflow. A second trough B ″ contains an alkaline bath that is somehow composed (dissolution of soda

etc.). A third trough B '"contains a soap bath. These three troughs, like trough B, are provided with guide and pressing rollers. A drying cylinder A" is similar to those already described above. A heater is BEZW in an enclosed space. in 'a hot air chamber M arranged. Of the six fans E E E 'E' E "E", E 'E' suck the heated air out of the room M and press the same through the openings of the hollow shaft F 'into the interior of the drying cylinder, the circumference of which is the tape to be dried, respectively. Fliefs, and which is thus permeated by the hot air. This hot air passes from chamber V into chamber L and here again passes through the jacket of the drying cylinder, as it exits chamber L 'under pressure on the one hand, and through fans EE on the other, which are connected to the hollow shaft of cylinder A. stand, sucked up and led outwards. In order to be able to regulate the heat in the drying room L L ', this room is connected to the hot air room M as well as to the free air through openings provided with sliders, which connection by opening or. Closing the corresponding slide is established or interrupted. The fans i? "E" take hot air from the space M and guide it, like the other cylinders, through the belt or flow surrounding them. Through openings provided with sliders at suitable points in the pipeline, it is also possible here to increase the temperature or to increase the temperature. to humiliate. Both the three drying cylinders and the pressing rollers are set in rotation by wheels. The number of revolutions is determined in such a way that the belt to be cleaned and dried runs through the device with advantageous tension. On the rake there are spools carrying the ribbons in such numbers that these ribbons, when they run side by side, form a full and even flow. The tapes enter trough B and become saturated with the acidic bath liquid. After this liquid has been withdrawn from the belts as much as possible by the pressure of the first pair of press rollers, they run around the small guide roller H in order to be guided over the circumference of the first drying cylinder. The second role .W leads the tapes to the second drying cylinder A ', to which they are also supplied or respectively by small rollers H H. be removed. The temperature of the belts during the first revolution of the drum is kept so low that they leave the room L dry or at least almost dry to get into the room L ', the temperature of which is correspondingly higher, to completely remove the vegetable, now charred impurities to . dry. From the second drying cylinder, the strip enters trough B ', in whose bath liquid the acid still contained in the strip is washed out as completely as possible. Any remaining acid is neutralized in the alkaline bath in trough B ", while the soap bath in trough B '" removes any neutral salts that may now be present. After it has passed through the last pre-press rollers, the belt steps onto the third drying cylinder, which means that the cleaning process is complete after drying has taken place here. Reels like those that feed the machine take up the tape again at the end of the path described, and in fact you can use a smaller number of them here because of savings by feeding several tapes onto one reel. Patent claims:

1. The process of cleaning the staple fiber from vegetable impurities by Charring and leaching of the same, while the textile to be cleaned is moving is in the state of a band or flux, in order, through this division, to exert the effect of the To increase reagents, and also not to change the position of the fibers and thus a tearing and corresponding shortening of the same by the comb drum respectively To prevent coating drum.

2. The contiguous arrangement of the trough B, the drying chamber LL ' and the troughs B' B "B '" in connection with any number of guide rollers, pre-pressing rollers CCCC, drying cylinders AA' A " and heating device M.

3. The construction of the drying cylinder, in particular the arrangement of the hollow shaft F provided with outlet openings in connection with the fans EEE 'E' E "E" and the hot air space M.
