Patentirt im Deutschen Reiche vom 16. October 1877 ab.Patented in the German Empire on October 16, 1877.

Der Gegenstand unserer Erfindung betrifft ein Verfahren, die Wolle von den Schaf häuten vollkommen im Zustande des Vliefses abzunehmen und nebenbei eine gründliche Waschung, Entfettung und Bleichung der Wolle zu erzielen.The subject of our invention relates to a method which completely hides the wool from the sheep to be removed in the state of the fleece and, in addition, thorough washing and degreasing and bleaching of the wool.

Die verschiedenen Operationen, welche nach den bis jetzt im Gebrauche befindlichen Verfahrungsweisen vollzogen werden mufsten, um von den getrockneten Schaf häuten, namentlich den amerikanischen, die Wolle zu gewinnen, sie zu waschen und zu entfetten, sind die folgenden :The various operations that follow the procedures in use so far had to be done in order to obtain the wool from the dried sheep, especially the American ones to wash and degrease are the following:

i. Man läfst die Felle ungefähr 28 Stunden lang in kaltem Wasser weichen.
• 2. Man hängt die Felle alsdann in Trockenstuben auf, worin man sie so lange läfst, bis sie in einen Zustand der Erhitzung und Gährung übergegangen sind, in welchem die Wolle von der Haut abgestreift werden kann. Damit diese Gährung vollständig, und hinreichend eintrete, sind im Sommer 24 bis 48 Stunden und im Winter 4 bis 5 Tage nöthig, manchmal noch mehr.i. Soak the skins in cold water for about 28 hours.
2. The pelts are then hung up in drying rooms, in which they are left until they have passed into a state of heating and fermentation in which the wool can be stripped from the skin. For this fermentation to take place completely and sufficiently, 24 to 48 hours are necessary in summer and 4 to 5 days in winter, sometimes even more.

3. Wenn die Felle aus der Trockenstube kommen, werden sie enthaart.3. When the skins come out of the drying room, they are depilated.

4. Nach dem Enthaaren kommt das Waschen der Wolle nach verschiedenen Methoden, Kältwäsche, Warmwäsche etc. Die Wäsche erfordert die Anwendung von Maschinen, worin die Wolle zerschlagen wird, und nur in einem Zustand der Verwirrung und Verfilzung aller Haare dieselben verläfst.4. After dehairing, the wool is washed using different methods, cold washing, Warm laundry etc. The laundry requires the use of machines, in which the wool is smashed, and only in a state of confusion and matting of all hair the same expires.

Am Ende aller dieser Operationen, welche zusammen im Mittel eine Woche Zeit erfordern, hat man eine durch die Maschine zerschlagene Wolle und eine durch die Behandlung in den Trockenstuben verdorbene Haut.At the end of all these operations, which together require an average of one week, one has a wool that has been broken by the machine and one by the treatment in the Drying room spoiled skin.

Das von uns erfundene Verfahren unterscheidet sich von dem gewöhnlichen vollständig durch die Operationen, welche es erfordert, sowie durch die Resultate, die es ergiebt. In weniger als zwei Stunden werden damit die am schwierigsten zu behandelnden Felle fertig gemacht und wir erlangen eine flockige und in Vliefsen zusammenhängende schöne, ungerissene Wolle, wie sie bei dem gewöhnlichen Verfahren nie erreicht wird, sowie eine Haut, welche in keiner Weise alterirt ist.The method we invented is completely different from the ordinary one by the operations it requires and the results it gives. In It takes less than two hours to finish the most difficult-to-treat skins and we obtain a flaky and in Vliefsen coherent beautiful, uncracked Wool, as it is never achieved with the usual method, as well as a skin which in is in no way altered.

Auf gewöhnliche Felle angewendet, erfordert unser Verfahren kaum einige Minuten.Applied to ordinary pelts, our procedure hardly takes a few minutes.

Nach vielen und wiederholten Versuchen hat sich unser Verfahren folgendermafsen gestaltet:After many and repeated attempts, our process turned out to be as follows:

1. Man legt die trockenen aus Amerika oder aus anderen fremden Ländern stammenden Felle 8 bis 10 Minuten lang in ein lauwarmes Bad von reinem Wasser von 50 bis 60° C., dem man · irgend ein Entfettungsmittel, als Soda, Seife etc. zugesetzt hat. Für frischere Felle, einheimische, welche von Thieren kommen, die erst kurze Zeit zuvor geschlachtet sind, genügt 3 bis 5 Minuten langes Eintauchen.1. The dry pelts coming from America or from other foreign countries are laid 8 to 10 minutes in a lukewarm bath of pure water at 50 to 60 ° C, to which one any degreasing agent, such as soda, soap etc. has been added. For fresher skins, locals, which come from animals which have only been slaughtered a short time before, 3 bis is sufficient Immersion for 5 minutes.

2. Unmittelbar nach dem Bad läfst man die Felle zwischen einer Walzenpresse durchgehen, welche hinreichend Kraft besitzt, allen Schweifs und alles Fett, sowie den Schafmist und andere Verunreinigungen aus der Wolle zu entfernen.2. Immediately after the bath, the skins are passed between a roller press, which has sufficient strength, all tail and all fat, as well as sheep dung and others Remove impurities from the wool.

3. Von der Walzenpresse weg werden die Felle noch warm in einer Reinigungsmaschine (Machine sabreuse du systeme Chandet ä Rouen) oder einer anderen passenden Maschine von allen der Wolle anhängenden Unreinigkeiten und fremden Körpern befreit und gleichzeitig gründlich gewaschen mit kaltem, lauem oder warmem Wasser, welches man im Ueberflufs zwischen den Tambour der Maschine und die Tafel, worauf das Fell liegt, einfliefsen lassen mufs.3. Away from the roller press, the skins are still warm in a cleaning machine (Machine sabreuse du systeme Chandet a Rouen) or another suitable machine from All impurities and foreign bodies attached to the wool are freed and at the same time thoroughly washed with cold, lukewarm or warm water, which one overflows between The drum of the machine and the board on which the skin lies must be flowed in.

4. Die nun von allen fremden Körpern befreiten und vollkommen gewaschenen Felle kommen nun ungefähr 10 Minuten lang in einen, laues Wasser enthaltenden Trog, worin die Haut zum Zwecke des Enthaarens aufgeweicht wird.4. The pelts now freed from all foreign bodies and completely washed come now for about 10 minutes in a trough containing lukewarm water, in which the skin is softened for the purpose of depilation.

5. Kräftiges Auspressen des Wassers mittelst einer Walzenpresse, um die Felle trocken zu machen. Unmittelbar darauf werden dieselben in einer mit der Presse verbundenen Schlagmaschine, welche das Fell heftig schwingt und schüttelt, bearbeitet, wodurch die Wolle sich wieder aufstellt und noch mehr kräuselt.5. Vigorous squeezing of the water by means of a roller press to dry the skins do. Immediately afterwards the same are in a hammer machine connected to the press, which the fur vibrates and shakes violently, processed, whereby the wool itself back up and curl even more.

6. Während die Felle noch lau sind, werden dieselben auf der Fleischseite mittelst eines Pinsels mit irgend einer die Enthaarung befördernden Flüssigkeit bestrichen.6. While the skins are still tepid, they are made on the flesh side by means of one Brush with any liquid that promotes depilation.

7. Endlich erfolgt das Enthaaren der Felle entweder durch Hand oder auf mechanischem Wege. Sodann läfst man die Felle trocknen.7. Finally, the pelts are dehaired either by hand or by mechanical means Ways. The skins are then left to dry.

Die so erhaltene Wolle ist flockige Wolle. Um vliefsige oder daunige Wolle zu erhalten, folgt auf das angegebene Verfahren noch das nachfolgende.The wool thus obtained is fluffy wool. To obtain full or downy wool, the following procedure follows the specified procedure.

9. Strongly squeezing the water out of the wool, either by a roller press or any other press.

10. Drying the wool treated in this way. The wool is thus obtained, as intended, in a flaky, fleecy and downy state.

After having undergone the first five operations on the skins, you can do them, instead of spreading the depilatory liquid, as indicated under 6, into the drying room bring, as has been done so far in the known method. The depilation of the skins will now be done much easier and faster because the skins are still quite warm ■ come into the drying room, and in this state the wool is more easily removed from the skin separates.

The wool separated from the hides can now be subjected to operations 8, 9 and 10 and one will get a wool as fluffy and crinkled as if one had used the depilatory composition, only with the remarkable The difference is that the wool becomes yellowish when it is in the drying room, and less white. The bleaching is an entirely optional operation, which is related using the method described above by adding a bleaching substance to the tepid bath mentioned under 4 can be performed while the skins are being dipped. The skins are left for 10 minutes longer in the liquid and then proceed with the operations as above described, continued.
