Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Doppelschläuchen oder Doppelfaltenschläuchen mit Hilfe von zwei getrennten halbkreisförmigen Kernen und besteht darin, daß die Formkerne an einem Ende oder an beiden Enden in normale kreisförmige Kerne auslaufen, so daß die ganze Form an den Enden gabelförmig gestaltet ist.The invention relates to a device for the production of double hoses or double corrugated hoses with the help of two separate semicircular cores and consists in that the mold cores on one End or both ends in normal circular cores, so that the whole shape is forked at the ends is.

Eine derartige Form bietet den erheblichen Vorteil, daß mit ihr Schläuche für Atemschutzgeräte hergestellt werden können, deren Enden, jedes für sich, an einen gesonderten Anschluß angeschlossen werden können. Gerade für Atemschutzgeräte ist eine derartige Möglichkeit wichtig und vorteilhaft.Such a shape has the considerable advantage that it uses hoses for breathing apparatus can be produced, the ends of which, each for itself, to a separate Connection can be connected. Such is the case especially for breathing apparatus Opportunity important and beneficial.

Man hat schon vorgeschlagen, namentlich für Feuerlöschzwecke bestimmte Doppelschläuche dadurch herzustellen, daß man zwei halbkreisförmig gestaltete Kerne mit einer Reihe von Lagen aus Kautschuk und Gewebe nacheinander umgibt und die Kerne dann durch Umlegen weiterer Gewebe- und Kautschukschichten zu einem zylinderförmigen Rohr vereinigt, das außen noch mit Verstärkungen zur Aufnahme des Innendruckes versehen wird.It has already been suggested that double hoses be designed specifically for fire-fighting purposes by making two semicircular cores with a number of layers of rubber and Tissue surrounds one after the other and the nuclei are then turned over by further tissue and Rubber layers combined to form a cylindrical tube with reinforcements on the outside is provided to absorb the internal pressure.

Bei den bekannten Schläuchen handelt es sich um Hochdruckschläuche, nicht um FaI-tenschläuche wie hier. Auch ist die Form nicht so gestaltet, daß der fertige Doppelschlauch an seinen Enden 'in zwei einzelne Schläuche auslauten kann.The known hoses are high-pressure hoses, not false hoses like here. Also, the shape is not designed in such a way that the finished double hose is split into two individual ends at its ends Can ring out hoses.

Auf der Zeichnung ist in
Abb. ι ein mit Hilfe der Vorrichtung gemäß der Erfindung hergestellter fertiger Doppelschlauch teilweise im Schnitt,The drawing shows in
Fig. Ι a finished double hose produced with the aid of the device according to the invention, partially in section,

Abb. 2 ein Querschnitt durch die Form dargestellt.Fig. 2 shows a cross section through the mold.

Die Form besteht aus den beiden halbkreisförmigen Kernen α und h, die an ihrem einen Ende in normale kreisförmige Kerne auslaufen und die so gelegt werden, daß zwischen ihnen ein Spalt c verbleibt. In diesen Spalt wird unvulkanisierte Kautschukmischung hineingebracht und in üblicher Weise um die Kerne und ihre Verlängerungen die Schlauchaußenwand aus unvulkanisierter Kautschukmischung gewickelt, wobei um die Schlauchaußenwand noch Fäden zum Herstellen der Falten, wie ebenfalls bekannt, gewunden werden können. Beim Vulkanisieren verbindet sich im wesentlichen der in dem Spalt befindliche unvulkanisierte Kautschuk mit dem Kautschuk der Schlauchaußenwand, so daß ein aus zwei halbkreisförmigen Hälften bestehender Doppelschlauch entsteht, der an einem Ende in zwei normale Schläuche ausläuft und aus dem man die Kerne durch Herausziehen der einzelnen Teilstücke entfernt.The mold consists of the two semicircular cores α and h, which terminate at one end in normal circular cores and which are placed in such a way that a gap c remains between them. Uncured rubber mixture is brought into this gap and the tube outer wall made of unvulcanized rubber mixture is wound in the usual manner around the cores and their extensions, with threads for making the folds, as is also known, can be wound around the tube outer wall. During vulcanization, the unvulcanized rubber in the gap is essentially combined with the rubber of the hose outer wall, so that a double hose consisting of two semicircular halves is created, which ends at one end in two normal hoses and from which the cores can be removed by pulling out the individual sections removed.
