KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die aus Kasein oder anderen quellbaren Stoffen hergestellten plastischen Massen zeigen bei ihrer Verarbeitung zu Stäben je nach der Bildsamkeit der Masse, dem angewendeten Druck und der Wärme ein ungleichmäßiges Verhalten. Dies tritt bei den erhaltenen Stäben insofern in Erscheinung, als sie bei einer bestimmten gleichbleibenden Weite des Kopfstückes der Formpresse keinen gleichmäßigen Durchschnitt aufweisen. Um das ungleichartige Verhalten der bildsamen Masse beim Formen zu Stäben zu regeln, wird gemäß der Erfindung ein Kopfstück der Formpresse verwendet, das aus an sich bei Klemm- oder Einspannfuttern bekannten Einzelheiten besteht. Es besitzt innerhalb kegelig ineinander geführter Büchsen einen zylindrischen Körper, dessen Weite während des Arbeitsganges derart eingestellt werden kann, daß ein Stab von dem gewünschten Durchschnitt erhalten wird, und der außerdem die Gewinnung von Stäben von verschiedener Dicke mit Hilfe desselben Kopfstückes ermöglicht. In der Zeichnung ist die Erfindung in zwei Ausführungsformen dargestellt.The plastic masses produced from casein or other swellable substances show in their processing into rods, depending on the malleability of the mass, the one used Pressure and heat show uneven behavior. This occurs with the received Rods in appearance insofar as they are at a certain constant width of the Head of the molding press do not have a uniform cross-section. About the disparate behavior of the malleable mass to regulate when forming rods, a head piece of the molding press is according to the invention used, from details known per se in clamping or clamping chucks consists. It has a cylindrical bushing inside conically nested bushes Body, the width of which can be adjusted during the operation in such a way that a stick of the desired average is obtained, and that also the extraction of bars of different thicknesses with the help of the same head piece. In the drawing, the invention is shown in two embodiments.
Fig. ι und 2 zeigen im Längsschnitt und in Oberansicht die eine Ausführungsform. Auf dem Gewindeteil α des Kopfstückes ist eine Überfallmutter b aufgeschraubt, die überFig. Ι and 2 show in longitudinal section and in top view the one embodiment. A lock nut b is screwed onto the threaded part α of the head piece, which over
•30 die kegelig gestaltete Büchse c greift. In der letzteren ist eine Hülle d angeordnet, die mit einer entsprechend kegelig ausgebildeten Außenfläche und mit einem Schlitz d1 versehen ist. In der Hülse d liegt eine Schraubenfeder e, deren oberes Ende, gegen den vorspringenden Rand der Hülse d stößt. Beim Anziehen der Mutter b drückt die Hülse d mittels der Büchse c auf die Schraubenfeder, die sich entsprechend verengert, indem sie sich nach unten ausdehnt.• 30 the tapered sleeve c engages. In the latter, a casing d is arranged, which is provided with a correspondingly conical outer surface and with a slot d 1 . In the sleeve d is a helical spring e, the upper end of which abuts against the protruding edge of the sleeve d. When the nut b is tightened, the sleeve d presses by means of the sleeve c on the coil spring, which narrows accordingly by expanding downwards.
Fig. 3 und 4 zeigen im Längsschnitt und im Schnitt nach Linie A-B eine andere Ausführungsform, bei der in der geschlitzten Hülse d ein Mantel f angeordnet ist, der der Länge nach aufgeschnitten ist und mit seinen zugeschärften Rändern übereinändergreift. Beim Anziehen der Mutter b drückt die Hülse d auf den Mantel f, der sich entsprechend verengert.3 and 4 show, in longitudinal section and in section along line AB, another embodiment in which a jacket f is arranged in the slotted sleeve d , which is cut open lengthwise and engages over the edges with its sharpened edges. When the nut b is tightened, the sleeve d presses on the jacket f, which narrows accordingly.
