Description
Verfahren zur Herstellung von Formstücken aus Kaseinkunsthorn Man hat bereits vorgeschlagen, weiche plastische Kaseinmassen für die Kunsthornerzeugung mit Hilfe einer mit verlängertem Rohrmundstück versehenen Strangpresse auf den Boden einer Hohlform von entsprechender Tiefe in der Weise zu bringen, daß die Form unter leichtem Gegendruck steht und bei der Füllung infolge des Druckes der aus dem Mundstück austretenden Masse nach und nach zurückweicht. Die in dieser Weise hergestellten Formstücke ergeben beim Härten und Trocknen ein minderwertiges Kunsthörn. Um ein wirklich gutes Kunsthorn in Formstücken zu erzeugen, muß von einer ziemlich festen elastischen Kaseininasse ausgegangen werden, wie sie in bekannter Weise durch Preßknetung von wenig angefeuchtetem Kasein erhalten wird. Um diese Masse in die Hohlform überzuführen und ihr eine dem Innenraum der Form entsprechend-- Gestalt zu geben, wird nach der Erfindung der hohe Druck ausgenutzt, unter dem die Masse aus der Preßknetvorrichtung austritt, die nach Art der Spindelstrangpresse arbeitet. Die aus dem Mundstück austretende Masse wird unmittelbar in die an das Mundstück, anschließende Form gepreßt.Process for the production of molded parts from artificial casein horn Man has already proposed soft plastic casein masses for artificial horn production with the help of an extruder equipped with an extended pipe mouthpiece on the floor to bring a hollow form of appropriate depth in such a way that the form under There is a slight counterpressure and during the filling as a result of the pressure from the mouthpiece emerging mass gradually recedes. Those made in this way When hardened and dried, molded pieces result in an inferior artificial horn. To a To produce really good artificial horn in fittings has to be done by a pretty solid one elastic casein mass are assumed, as they are in a known manner by press kneading is obtained from slightly moistened casein. To transfer this mass into the hollow form and to give it a shape corresponding to the interior of the form, is according to the Invention exploited the high pressure under which the mass from the press kneading device exits, which works like the screw extruder. The one emerging from the mouthpiece The mass is pressed directly into the mold adjoining the mouthpiece.
Es muß in besonderer Art für einenWiderstand gesorgt werden, damit eine Formung der völlig zusammenhängenden Kaseinmasse in der Hohlform erreicht wird. Dies ist besonders wichtig bei der Herstellung von Blöcken aus Kaseinmasse. Gemäß der Erfindung wird hierbei der. Boden der Form beweglich angeordnet und auf ihn ein genügender Gegendruck ausgeübt. Um ein nachteiliges Vorkühlen der zuerst in die Form übergeleiteten Masse vermeiden zu können, wird das Mundstück mehrerer Pressen an die Form angeschlossen. Eine Vorrichtung zur Ausführung des Verfahrens ist auf der Zeichnung veranschaulicht.There must be a special kind of resistance to it a molding of the completely coherent casein mass in the hollow mold is achieved. This is especially important when making blocks from casein mass. According to the invention here is the. The bottom of the mold is movably arranged and on it a sufficient counter pressure is exerted. In order to avoid detrimental pre-cooling of the first in To be able to avoid the mass transferred to the form, the mouthpiece of several presses becomes attached to the shape. An apparatus for carrying out the method is on illustrated in the drawing.
Abb. i zeigt die Vorrichtung im Schnitt und Abb. 2 in Vorderansicht.Fig. I shows the device in section and Fig. 2 in front view.
Vor einer in ununterbrochenem Betriebe arbeitenden Preßknotenvorrichtung d nach Art einer Spindelstrangpresse ist eine Form h mit beweglichem, unter Gegendruck stehendem Boden angeordnet. Die Preßknetvorrichtung und die Form mit beweglichem Boden sind unmittelbar miteinander verbunden, so daß die fertiggeknetete Masse aus der Preßknetvorrichtung in die Form überfließt.In front of a press knotting device working continuously d in the manner of a screw extruder is a form h with movable, under counter pressure arranged standing floor. The press kneading device and the mold with movable Bottom are directly connected to each other, so that the finished kneaded mass from the press kneading device overflows into the mold.
Der Vorteil des neuen Verfahrens ist nicht nur die völlige Einheitlichkeit der Masse im Formstück beliebiger Ausmessungen und des aus dem Masseformstück hergestelltenKunst= Korns, sondern die auch in allen Teilen des Formstückes der Masse bewahrte Gleichmäßigkeit im Wassergehalt. Es wird dadurch ausgeschlossen oder auf das mindeste Maß beschränkt, daß die geformte Masse sich beim Härten und nachfolgenden Trocknen infolge eintretender Spannungsunterschiede in dein Stück verzieht oder wirft.The advantage of the new procedure is not only the complete uniformity the mass in the shaped piece of any dimensions and the art made from the mass shaped piece = Grain, but also the uniformity preserved in all parts of the molding of the mass in water content. It is thereby excluded or limited to the minimum, that the molded mass during hardening and subsequent drying as a result of occurring Differences in tension in your piece warps or throws.
