PATENTSCHRIFT
>£ 260956 '— KLASSE 39«. GRUPPE
H. DOGNY und V.HENRI in PARIS.
Patentiert im Deutschen Reiche vom 31. Januar 1911 ab.
Es ist bereits bekannt, Gegenstände aus Gummi herzustellen, bei denen durch Zusammenfügen
von gelochten und vollen Kautschukplatten, die miteinander zusammengeklebt sind, gleichmäßig verteilte Zellen hergestellt
sind. Um in diesen Zellen einen, größeren Gasdruck, als der Atmosphärendruck ist, zu
erzeugen, werden vor dem Vulkanisieren gaserzeugende Chemikalien in bestimmten Mengen
ίο in die einzelnen Zellen gebracht. Hierbei
wurde aber ein gleicher Gasdruck in allen Zellen nicht gewährleistet, da die Menge und
Zusammensetzung der gaserzeugenden Chemikalien nicht mit der erforderlichen Genauigkeit
innezuhalten ist.
Durch das vorliegende Verfahren wird aber der Nachteil des früheren Verfahrens vollständig
aufgehoben, indem nämlich bei dem beanspruchten Verfahren die einzelnen Platten vor ihrem endgültigen Zusammenkleben in
einer Form durch Einführen von Gas unter gleichen Innendruck gesetzt, alsdann
zusammengeklebt und schließlich vulkanisiert werden. Die Zellen erhalten daher einen absohlt
gleichmäßigen und größeren Druck als der Athmosphärendruck ist.
Das Verfahren wird wie folgt ausgeführt: In bekannter Weise werden gelochte und
volle Kautschukplatten übereinander angeordnet. Die Kautschukplatten können durchweg
oder teilweise gelocht sein. Die Platten werden alsdann in eine Form gebracht, die luftdicht
abgeschlossen wird. Auf der beiliegenden Zeichnung sind zwei Ausführungsbeispiele
der Formen und der herzustellenden Gegenstände gegeben. Zur Füllung der Hohlräume
mit Gas oder Luft unter Druck wird vorher vorbereitetes Gas oder atmosphärische Luft
benutzt und dieses Gas oder diese Luft in den Gegenstand in einem Zustande eingeführt,
bei dem die Platten miteinander zusammenhängen, und zwar vor dem Vulkanisieren. Zur Erzielung eines absolut gleichmäßigen
Druckes in den einzelnen Teilen des Gegenstandes ist es vorteilhaft, die Hohlräume rßgelmäßig
anzuordnen.
Wie aus Fig. 1 der Zeichnung zu erkennen ist, wird durch äußere volle Platten 1 eine
innere gelochte Platte 2 umschlossen. Die Ränder dieser Platte sind miteinander verklebt
oder in sonst geeigneter Weise vereinigt, so daß sie den Druck des Gases oder der
Luft aushalten. Schon vorher können durch Einblasen von Druckluft die Platten aufgetrieben
sein, so daß der Gegenstand die Form eines gewölbten Kissens erhält. Alsdann wird
er in die Presse 3 eingelegt und der Deckel 4 so aufgesetzt, daß er das in den Hohlräumen
befindliche Gas komprimiert, worauf er mit Hilfe von Bolzen durch den Druck einer
Presse o. dgl. fest verschlossen wird. Die Kautschukplatten bleiben während einer ausreichenden
Zeit unter Druck und vereinigen sich hierdurch derart mi-teinander, daß der
Gegenstand aus der Form herausgenommen und zum Vulkanisieren gebracht werden kann,
ohne daß die Platten sich infolge der Wir-■ kung des Innendruckes wieder voneinander
lösen. Die Vulkanisation des Gegenstandes kann aber auch in derselben Form geschehen.
Die Form kann aber auch, wie Fig. 2 zeigt, für verschieden große Gegenstände gebraucht
werden, indem sie nämlich in einen besonderen Behälter 6 gesetzt wird, durch
dessen Deckel ein Luft- oder Gaszuführungsrohr 7 hindurchgeht. Bei dem Deckel ist
ein Druckmesser 8 und ferner ein durch eine Schraubenspindel 9 und eine Mutter 10 zu bewegender
Preßdeckel vorgesehen, der in die Form 5 hineinpaßt.
Wird der Gegenstand in die Form 5 eingesetzt und Druckluft in den Behälter 6 geleitet,
so dringt diese durch die Verbindungsstelle der Presse hindurch und gelangt zwischen
die einzelnen Platten, die noch nicht miteinander vereinigt sind, sondern sich leicht
voneinander lösen.
Nach Erreichung des gewünschten Druckes werden die Teile der Presse festgezogen, wodurch
die Platte 1 und 2 kräftig gegeneinander gepreßt werden, so daß sie sich miteinander
vereinigen und sich an die Innenwand der Presse anschmiegen, ohne daß man eine Zerstörung
der Hohlräume zu befürchten hat. Nach Ablauf eines ausreichenden Zeitraumes wird der Gegenstand entweder herausgenommen,
um vulkanisiert zu werden, oder es wird in der Presse selbst vulkanisiert.
Um eine Formveränderung der Hohlräume zu verhindern, kann in jedem Hohlraum eine
Kapsel aus schmiegsamem Stoff, beispielsweise einer Mischung von Glycerin und Gelatine
angebracht werden, die in zweckentsprechender Weise gehärtet ist, um den Zeitpunkt des
Erweichen s zu verzögern. Das eigentliche Verfahren bleibt aber stets dasselbe.
Nach dem vorliegenden Verfahren ist es auch möglich, auf die äußeren Flächen der
nicht vulkanisierten Kautschukplatten halb vulkanisierte Kautschukplatten derart aufzukleben,
daß ein Überzug gebildet wird, der gegen Gas undurchlässig, jedoch geeignet ist, sich
beim Vulkanisieren des ganzen Gegenstandes mit dem ihn umschließenden Kautschuk zu
vereinigen. Es ist alsdann nötig, zwischen die Kautschukplatten Metallröhrchen zu lagern,
um Luft oder Gas einzuführen. Nach Beendigung des Einleitens wird das Füllrohr zurückgezogen
und die Einführungsöffnung verschlossen, um das Gas oder die Luft nicht entweichen zu lassen.
Die nach dem vorliegenden Verfahren erzeugten Gegenstände werden dann weiter bearbeitet,
nötigenfalls in sich selbst gerollt und geformt, wobei eine Zerquetschung von Teilen
der Masse und das Eindrücken von Hohlräumen infolge des Gasdruckes, der durch die
Undurchlässigkeit der halb vulkanisierten Umhüllung in den Hohlräumen erhalten bleibt,
nicht zu befürchten ist.
