Hautfaserdarm sowie Vorrichtung zu dessen HerstellungSkin fiber intestine and device for it Manufacturing

Es ist bereits bekannt, diejenigen Teile einer tierischen Haut, die nicht zur Verarbeitung von Leder geeignet sind, zu quellen, um auf diese Weise den Verband der Kollagen-Pasern zu lockern. Die dabei resultierende Masse wird durch ringförmige Schlitze ausgepresst, wobei eine künstliche Wursthaut entsteht.It is already known to swell those parts of an animal hide that are not suitable for processing leather, in order to loosen the bandage of the collagen fibers in this way. The resulting mass is pressed through ring-shaped slots, creating an artificial sausage skin.

Die Verfahren zur Auflockerung des Kollagen-Verbandes sind in der Literatur beschrieben, so z.B. in den deutschen Patenten 686 891, 684 783, 638 585 und 664 127. Das Ausformen einer derartigen Fasermasse zu einem Kunstdarm ist schematisch aus der beiliegenden Pig. I ersichtlich.The methods for loosening the collagen bandage are described in the literature, e.g. in the German patents 686 891, 684 783, 638 585 and 664 127. The shaping of such a fiber mass into an artificial casing is shown schematically in FIG enclosed pig. I can be seen.

Man bringt die Masse M in einen Zylinder, welcher einen inneren Kern K enthält. Der Durchmesser des inneren Kernes K ist nur etwas geringer als der Durchmesser des ihn umgebenden Rohres mit den Wänden W. Drückt man nun mit Hilfe des Stempels A die Masse M gegen den Kern K, so wird die Fasermasse gezwungen, in den ringförmigen Schlitz einzudringen, welcherThe mass M is placed in a cylinder which contains an inner core K. The diameter of the inner core K is only slightly smaller than the diameter of the pipe with the walls W surrounding it. Now press with the help of the stamp A the mass M against the core K, the fiber mass is forced to penetrate into the annular slot, which

sich zwischen dem inneren Kern K und den Wänden W des Zylinders bildet. Am rechten rtundstüek tritt dann die Pa3ermasse in Form eines Schlauches aus.forms between the inner core K and the walls W of the cylinder. The Pa3ermasse then takes shape on the right round piece of a hose.

Die Fig. 2 stellt eine Aui3icht auf die Linie L-, , Lp der Fig. 1 dar. Es würde also der Darm zwischen dem Kern K und der Wand W auf den Beschauer zu ausgedrückt werden.FIG. 2 shows a view on the line L-,, Lp of FIG The intestine between the core K and the wall W would thus be expressed towards the observer.

Da beim Durchtritt der Masse M durch den ringförmigen Schlitz zwischen dem Kern K und der V/and W immer eine Orientierung der Hautfasern in der Austrittsrichtung des Darmes stattfindet, ist auch dessen Festigkeit in der Längsrichtung erheblich besser als in Querrichtung. Da jedoch ein Darm auch eine Querfestigkeit aufweisen muss, unterteilt man den Kern K - wie aus der Fig. 2 ersichtlich - in drei Segmente, von denen das mittlere K2 rotiert. Beim Überfliessen der rotierenden Fläche des Segments K2 werden die Hautfasern zum gros3en Teil in die Querrichtung orientiert. Beim anschlies3enden weiteren Passieren des Schlitzes zwischen dem feststehenden Segment K-, und der Aussenwand W wird eine derartige Verteilung der Fasern erreicht, dass etwa gleich viele Fasern in Längs- und Querrichtung orientiert sind. Selbstverständlich liegt auch ein grosser Teil der Fasern in einem Winkel zwischen der Längs- und der Querrichtung, Der entstehende Hautfaserdarm weist daher im wesentlichen gleiche Festigkeit in allen Richtungen auf.Since when the mass M passes through the annular slot between the core K and the V / and W there is always an orientation of the Skin fibers takes place in the exit direction of the intestine, its strength in the longitudinal direction is also considerably better than in the transverse direction. However, since a casing must also have transverse strength, the core K is subdivided as from the Fig. 2 can be seen - in three segments, of which the middle K2 rotates. When overflowing the rotating surface of the segment K2 are the skin fibers for the most part in the transverse direction oriented. When you then pass the slit between the fixed segment K- and the Outer wall W such a distribution of the fibers is achieved that approximately the same number of fibers are oriented in the longitudinal and transverse directions are. Of course, a large part of the fibers is also at an angle between the longitudinal and the transverse direction, The resulting skin fiber casing therefore has essentially the same strength in all directions.

909882/0640909882/0640

Erfindungsgemäss wird nun die Längsfestigkeit noch zusätzlich erhöht, wenn man die Oberfläche des feststehenden Segments K, mit Rillen, vorzugsweise in Längsrichtung des Darmes, versieht. In diesen Rillen lagern sich dann mehrere Hautfasern als Bündel zusammen, wodurch eben die LTngsreissfe3tigkeit zusätzlich ohne Beeinträchtigung der Querreissfestigkeit erhöht wird.According to the invention, the longitudinal strength is now additionally increases if the surface of the fixed segment K, provided with grooves, preferably in the longitudinal direction of the intestine. Several skin fibers are then stored as bundles in these grooves together, whereby the longitudinal tear strength is additionally increased without impairing the transverse tear strength.

Die Fig. 4 zeigt eine perspektivische Ansicht des Segments K-,, welches auf seiner Oberfläche Rillen R enthält. Diese Rillen sind nur etwa 0,1 - 0,5 mm tief. Der Abstand von Rille zu Rille ist vorzugsweise 0,3 mm. An den beiden Enden des Segments K, wird π*.-; die Rillentiefe nur 0,01 mm betragen lassen. Durch diese Mas3nahme wird das Eintreten der Masse in die Rillen erleichtert.Fig. 4 shows a perspective view of the segment K- ,, which contains grooves R on its surface. These grooves are only about 0.1-0.5 mm deep. The distance from groove to groove is preferably 0.3 mm. At both ends of the segment K, becomes π * .-; let the groove depth be only 0.01 mm. This measure makes it easier for the mass to enter the grooves.

Die Pig. 5 zeigt schematisch die Anordnung von endlos fortlaufenden Faserbündeln B innerhalb des Hautfaserdarmes, in dem ausserhalb der Bündel B die Fasern im allgemeinen statistisch verteilt liegen. Die Fasern in einem Faserbündel B weisen eine Länge von 1 mm bis zu einigen cm auf. Unmittelbar hinter einem Bündel B-, schliesst sich sofort ein Faserbündel Bp an usw. Obwohl also die Fasern längs einer durch mehrere hintereinander liegenden Bündel B-, , Bp usw. gebildete "Bündellinie" nicht endlos sind, wird die Reissfestigkeit in Längsrichtung um 50$ und mehr erhöht.The Pig. 5 shows schematically the arrangement of endlessly continuous fiber bundles B within the skin fiber intestine, in which outside the bundle B the fibers are generally randomly distributed. The fibers in a fiber bundle B have a length of 1 mm to a few cm. Immediately behind a bundle B-, a fiber bundle Bp immediately follows, etc. Although the fibers along a "bundle line" formed by several consecutive bundles B-,, Bp etc. are not endless, the tensile strength in the longitudinal direction is around 50 $ and more increased.

909882/0640909882/0640

stärkten Hautfaserdärme, ist besonders bei der Herstellung sehr langer und daher schwerer Würste vorteilhaft. Die Wurst wird bekanntlich nach dem Füllen - wie aus Fig. 6 ersichtlich am oberen Ende abgebunden und dann aufgehängt. An der Aufhängestelle hängt nun das gesamte Gewicht der Wurst an der dünnen abgedrehten Stelle. Bei der Verwendung von nicht Bündel-verstärkten Wursthüllen findet hier oftmals ein Einreissen statt.strengthened skin fiber intestines, is very special in the manufacture long and therefore heavier sausages are advantageous. The sausage is known to be after filling - as can be seen from Fig. 6 on tied off at the top and then hung up. At the hanging point The entire weight of the sausage now hangs on the thin, twisted point. When using non-bundle-reinforced Sausage casings often tear here.

Für manche Zwecke ist es vorteilhaft, auch die Oberfläche des rotierenden ,·■ Segmentes K^ mit Rillen zu versehen.For some purposes it is advantageous to also modify the surface of the rotating, · ■ segment K ^ to be provided with grooves.

Es ist ferner möglich, die Rillen R auf der Oberfläche des Segments K-* spiralförmig anzuordnen. Auf diese Weise werden die Bündellinien im Wurstdarm nicht in Längsrichtung angeordnet, sondern in Spiralform.It is also possible to arrange the grooves R in a spiral shape on the surface of the segment K- *. Be that way the bundle lines in the sausage casing are not arranged lengthways, but in a spiral shape.

Selbstverständlich kann auch die der Oberfläche des Segments K-z gegenüberliegende Wand eine Gravour aufweisen. Besonders günstige Ergebnisse erhält man dann, wenn man eine Pressapparatur verwendet, wie in der.,deutschen Patentschrift 650 beschrieben. Dort wird dasselbe Prinzip wie oben geschildert befolgt, jedoch wird die Masse durch Röhren direkt auf das rotierende Segment K2 geleitet.Of course, the wall opposite the surface of the segment Kz can also have an engraving. Particularly favorable results are obtained when using a pressing apparatus as described in German Patent 650. The same principle as described above is followed there, but the mass is passed through tubes directly onto the rotating segment K 2 .
