Description

Verfahren zum Vulkanisieren von beliebig langen Gummischläuchen in Formen Die Erfindung betrifft ein Verfahren zum Vulkanisieren von beliebig langen Gummischläuchen in Formen unter Anwendung inneren Überdruckes. Siebesteltt darin, daß die Schläuche abschnittweise in geheizten geraden l-illenforinen vulkanisiert «-erden.Process for vulcanizing rubber hoses of any length in Shapes The invention relates to a method for vulcanizing any length Rubber hoses in molds using internal overpressure. She determines in it that the hoses are vulcanized in sections in heated straight l-illen forines "-earth.

Es ist bekannt, Riemen beliebiger Länge absatzweise in einer Presse zu vulkanisieren; ferner ist es bekannt, in einer Presse kurze Schlauchstücke auf Dornen zu vulkanisieren. Gummischläuche hat man schließlich schon in beliebigen Längen durch Hindurchziehen durch gerade Formen und in Spiralen in Forinen unter innerem Überdruck vulkanisiert.It is known to intermittently use belts of any length in a press to vulcanize; It is also known to use short pieces of tubing in a press Vulcanize thorns. After all, rubber hoses are already available in any Lengths by pulling through straight shapes and in spirals in forins internal overpressure vulcanized.

Durch das Verfahren gemäß der Erfindung wird erreicht, daß die Schläuche außen glatt sind, ohne daß sie beim Vulkanisieren eine Krümmung erhalten.By the method according to the invention it is achieved that the hoses are smooth on the outside without being curved during vulcanization.

Nachdem die Schläuche auf den Dornen in üblicher Weise fertiggestellt worden sind, werden sie von diesen abgezogen, um in Formen vulkanisiert zu werden.After the hoses are finished on the mandrels in the usual way are peeled off from them to be vulcanized into molds.

Die Formen bestehen aus zwei flachen Eisenplatten, in die halbrunde Rillen eingefräst worden sind. Von diesen Eisenplatten wird die eine Hälfte an der unteren und die andere Hälfte an der oberen Heizplatte einer Vulkanisierpresse so befestigt, daß die beiden Hälften einen vollkommen runden Hohlraum einschließen. In diese Höhlung wird der Schlauch eingelegt und dann an seinen beiden Enden verschlossen. An einem Ende des Schlauches wird ein Abdichtungspfropfen angebracht; das andere Ende dagegen wird so an eine Muhe angebracht, daß durch die Muffe eine Flüssigkeit oder Luft oder ein Gas in den Schlauch eingeführt werden kann.The forms consist of two flat iron plates, in the semicircular one Grooves have been milled. Half of these iron plates are attached to the lower and the other half on the upper heating plate of a vulcanizing press like this attached so that the two halves enclose a perfectly round cavity. The hose is inserted into this cavity and then closed at both ends. A sealing plug is attached to one end of the hose; the other The end, on the other hand, is attached to a pressure in such a way that a liquid flows through the sleeve or air or a gas can be introduced into the hose.

Ist dies geschehen, so wird die geheizte Presse verschlossen, und die Temperatur der Heizplatten überträgt sich auf die Formplatten, so daß der eingeschlossene Teil des beliebig langen Schlauches vulkanisiert wird. wobei das Auftreibinittel den Schlauch gegen die Wandung der Formplatten preßt.Once this has happened, the heated press is closed and the temperature of the heating plates is transferred to the mold plates, so that the enclosed Part of the hose of any length is vulcanized. wherein the buoyant presses the hose against the wall of the mold plates.

Ist die nötige Zeit verstrichen, so schließt man die Zuführung des Auftreibmittels una öffnet die Presse, um den Schlauch um die Länge des vulkanisierten Teiles vorzuschieben. Der geschilderte Vorgang wird so oft wiederholt, wie die Länge des Schlauches durch die Länge der Formplatten teilbar ist.If the necessary time has passed, the feed of the The expanding agent una opens the press to the hose around the length of the vulcanized Part to advance. The described process is repeated as often as the length of the hose is divisible by the length of the mold plates.
