Description
Gummischlauch mit schraubengangförmig verlaufenden Falten mit Gewebeumlagen Bekannt sind Gummischläuche mit Gewebeumlage und mit ringförmig um die Schlauchachse gerichteten Falten (auch Harmonikaschläuche genannt), die eine große Gelenkigkeit und Biegsamkeit unter Vermeidung der Gefahr eines Knickens zeigen. Diese haben jedoch den Nachteil, daß die Herstellung dieser ringförmigen Falten sehr umständlich und zeitraubend ist.Rubber hose with helical folds with fabric wraps Known are rubber hoses with a fabric layer and with a ring around the hose axis directed folds (also called harmonica tubes) that have great flexibility and exhibit flexibility while avoiding the risk of kinking. However, these have the disadvantage that the production of these annular folds is very cumbersome and is time consuming.
Weiter sind Schläuche bekannt, bei denen auf einem Dorn nach einer Schraubenlinie ein Draht aufgewickelt wird, worauf auf diese Form Gummi und Gewebe aufgebracht wurden. Derartige Schläuche haben jedoch den Nachteil, daß sie sich bei einer Dehnung verdrehen, wodurch insbesondere an den Enden, mit denen der Schlauch angeschlossen wird, unzulässige Beanspruchungen und damit Lockerung und Undichtigkeit eintritt.Hoses are also known in which on a mandrel after a A wire is wound helically, after which rubber and fabric are applied to this shape were applied. However, such hoses have the disadvantage that they twist in the event of a stretch, thereby particularly at the ends with which the hose is attached is connected, inadmissible stresses and thus loosening and leakage entry.
Nach der Erfindung können diese Nachteile dadurch vermieden werden, daß die Gewebeumlagen aus geklebtem oder nahtlos erzeugtem dehnbarem Gewebeschlauch, z. B. Trikot, bestehen, der mit entgegengesetztem Drall so aufgebracht ist, daß der fertige Gummischlauch beim Dehnen in der Achsenrichtung kein oder nur ein ganz geringes Verdrehungsbestreben um die Schlauchachse aufweist.According to the invention, these disadvantages can be avoided by that the fabric layers are made of glued or seamlessly produced stretchable fabric tube, z. B. jersey exist, which is applied with the opposite twist so that the finished rubber hose has none or only a whole when stretching in the axial direction has little tendency to twist around the hose axis.
Ein solcher Schlauch kann auf folgende Weise hergestellt werden: Auf einen Dorn mit Kordelgewinde wird eine Gummilage aufgebracht und darüber ein nahtlos gewirkter Trikotschlauch geschoben. Alsdann wird der Trikotschlauch entgegen dem Drall der Schlauchfalten verdrallt und auf dem Dorn in an sich bekannter Weise durch Niederbinden gefaltet und das Ganze in diesem Zustande vulkanisiert.Such a hose can be made in the following way: On A rubber layer is applied to a mandrel with a cord thread and a seamless layer over it knitted tube tube pushed. Then the tube of the jersey is against the Twist of the hose folds twisted and on the mandrel in a known manner Tie down folded and the whole vulcanized in this condition.
Die Gewebeumlage kann auch mit einer Gummischicht bedeckt und in bekannter Weise mit Stoffbinden eingewickelt und vulkanisiert werden.The fabric sheathing can also be covered with a rubber layer and made in a well-known manner Way to be wrapped with cloth bandages and vulcanized.
Ein auf diese Weise hergestellter Schlauch bietet den weiteren Vorteil, daß der Strömungswiderstand gegen die durch den Schlauch durchströmenden Gase oder Flüssigkeiten vorteilhafterweise verringert und die Bildung von strömungslosen (toten) Winkeln, in denen Gase oder Flüssigkeiten dauernd vorhanden bleiben könnten, vermieden werden.A hose manufactured in this way offers the further advantage of that the flow resistance to the gases flowing through the hose or Liquids are advantageously reduced and the formation of no-flow (dead) Avoid angles in which gases or liquids could remain permanently present will.
Als Verwendungszweck wären insbesondere zu nennen: Atmungsschläuche, Schläuche für Gasschutzgeräte, biegsame Apparateschläuche u. dgl.The following should be mentioned in particular as intended use: breathing tubes, Hoses for gas protection devices, flexible apparatus hoses and the like.
Als Ausführungsbeispiel ist in der Zeichnung ein Atmungsschlauch dargestellt. Der Schlauch besteht aus der Seele i, den schraubengangförmig verlaufenden Falten 2 und einer nahtlosen Gewebeumlage 3.As an exemplary embodiment, a breathing tube is shown in the drawing. The tube consists of the core i, the folds running in the form of a helix 2 and a seamless fabric layer 3.
