Description

Es. ist bekannt aus The'rmoplasten hergestellte Schläuche mit einer Außenverstärkung aus thermoplastischem Material oder Draht zu versehen. It. is known from thermoplastics made hoses with a External reinforcement made of thermoplastic material or wire to be provided.

Gleichfalls bekannt sind Verfahren zum Hersteilen von Schläuchen mit zur Verstärku;ng dienender Außenwendel, bei welchen von einem doppelschichtigen Schlauch ausgegangen und mittels eines Werkzeugs eine Rille in der Außenschicht eingeschnitten wird. Processes for producing hoses are also known with an outer helix that is used for reinforcement, with a double-layered helix Run out hose and use a tool to make a groove in the outer layer is cut.

Die Erfindung betrifft ein Verfahren zum Herstellen von mit Verstärkungswebdeln versehenen Schläuchen aus thermoplastischen Material, bei welchem von einem doppelschichtigen, eine biegsame innere und eine steife äußere Schicht aufweisenden Schlauch ausgegangen wird und eine unmittelbar vor der Preßdüse der Strangpresse rotierende Schneidvorrichtung in der Außenschicht des Schlauches ohne Spanabhebung einen schraubenförmigen Schnitt erzeugt, wobei die Schraubenwindungen zwecks Bildung der Verstärkungswendel durch Strecken des aus der Strangpresse in noch formbarem Zustand austretenden Schlauches vonander entfernt werden. The invention relates to a method for producing reinforcing looms provided hoses made of thermoplastic material, in which a double-layer, a flexible inner and a stiff outer layer having tubing assumed and a cutting device rotating immediately in front of the extrusion press nozzle a helical cut in the outer layer of the hose without chip removal generated, wherein the screw turns for the purpose of forming the reinforcement helix Stretching the tube emerging from the extruder in a still malleable state be removed from each other.

Der Vorteil des Verfahrens besteht darm, daß an Werkstoff zur Herstellung der Außenschicht erheFblich gespart wird. The advantage of the method is that there is a material for manufacture the outer layer is saved considerably.

Dias Verfahren wird mit der in der Zeichnung dargestellten Vorrichtung, welche die Herstellung eines verstärkten Schlauches von unbegrenzter Länge gestattet, kontinuierlich vermittels zweier Strangpressen ausgeführt, die mit dem Material zur Bildung des Schlauches 1 und der Verstärkungswendel 2 gespeist werden und dieses mit ihren Leitungen A und A' an die Vorrichtung P lieferen, durch die lein aus zwei Schichten, nämlich einer inneren aus biegsamem Material und einer äuB,eren aus steifem Material blestehender Schlauch erzeugt werden kann. Beim Auslaß R der vereinigten Leitung rotiert eine Schneidvorrichtung V um die Achse der Preßdüse, die einen durch die Gesamtdicke der streiferen Außenschicht reichenden Einschnitt erzeugt. Dabei wird der austretende Schlauch, während sich das Material noch im plastischen Zustand befindet, in der Weise gezogen, daß die Schlauchseele gestreckt und die Schraubenwindungen des steiferen Außenmantels, der durchschnitten wurde, voneinander entfernt werden, wodurch sie einen vom Ausmaß des ausgeübten Zuges abhängigen, vorbestimmten Steigungswinkel einnehmen. Die Zugwirkung kann einfach durch das Gewicht des austretenden Schlauches hervorgebracht werden, der in einem, dem gewünschten Ausmaß der Streckung proportionalen Abstand vom Auslaß getragen wird. The process is carried out with the device shown in the drawing, which allows the manufacture of a reinforced hose of unlimited length, continuously carried out by means of two extrusion presses, which with the material to form the hose 1 and the reinforcing coil 2 are fed and this with their lines A and A 'to the device P, through the line of two Layers, namely an inner one made of flexible material and an outer one made of stiff material Material bleeding hose can be generated. At the outlet R of the combined Line rotates a cutting device V around the axis of the press nozzle, the one through the overall thickness of the stricter skin is created. Included becomes the exiting hose while the material is still in its plastic state is drawn in such a way that the hose core is stretched and the screw turns the stiffer outer jacket, which has been cut through, are removed from each other, whereby they have a predetermined pitch angle dependent on the extent of the pull exerted take in. The pulling effect can simply be determined by the weight of the exiting hose which is proportional to the desired extent of the stretching Distance from the outlet.

Es ist ersichtlich, daß man durch Verwendung von zwei oder mehr Schneidvorrichtungen an Stelle einer einzigen zwei oder mehr Wendeln erhalten kann. It can be seen that by using two or more cutting devices can have two or more coils instead of a single one.
