Führungsring 17 ist ferner eine das zu einem Rohr zusammengebogene Papierband 10 mantelförmig umhüllende elektrische Strahlungsheizung 20 vorgesehen, welche die Aufgabe hat, dieses Papierband auf die für die nachfolgende Innenkaschierung mit dem Kunststoffschlauch erforderliche Temperatur zu bringen und außerdem den Klebestreifen auf der einen Längskante des Papierbandes so hoch zu erhitzen, daß die nachfolgende Verklebung zu einer Längsnaht zwischen dem Druckrollenpaar 13, 15 eine dauerhafte ist. In the area between the spray nozzle 8 and the centering or guide ring 17, a paper tape 10 bent together to form a tube is also jacket-shaped enveloping electrical radiant heater 20 is provided, which has the task of this paper tape on for the subsequent inner lamination with the plastic tube to bring the required temperature and also the adhesive strip on one Heat the long edge of the paper tape so high that the subsequent gluing to a longitudinal seam between the pressure roller pair 13, 15 is a permanent one.
Die Arbeitsweise der Vorrichtung ist folgende: Der zunächst glatte, von einer Rolle ablaufende Papierstreifen (vgl. F i g. 1) wird über den Spritzkopfkörper hinweggeführt und hierbei allmählich zu einem offenen Zylinder zusammengebogen (vgl. F i g. 3). Dieses Zusammenbiegen erfolgt unter dem Zwang der Kreisringführung. Die einzelnen Phasen der Zusammenbiegung sind aus den Fig. 3 bis 8 erkennbar. Zunächst stehen die Kanten des gebogenen Papierstreifens noch verhältnismäßig weit auseinander (vgl. The operation of the device is as follows: The initially smooth, Paper strips running off a roll (see FIG. 1) are placed over the spray head body led away and gradually bent into an open cylinder (cf. F i g. 3). This bending takes place under the constraint of the circular ring guide. the individual phases of the bending together can be seen from FIGS. 3 to 8. First the edges of the bent paper strip are still relatively far apart (see.
Fig. 3), sodann gelangt die eine Kante des Papierstreifens vor die seitliche Spritzdüse (vgl. F i g. 4) wo diese Kante mit Klebstoff belegt wird. Sobald die Stelle des Schnittes V-V erreicht ist, also die Stelle, wo sich die Kreisringführung befindet, liegen sich die beiden Kanten des Papierstreifens bereits gegenüber, werden jedoch durch die Kreisringführung noch in bestimmtem Abstand gehalten. An der Stelle des Schnittes VI-VI, wo also die Druckrollen angeordnet sind, erfolgt dann das Zusammenpressen der Bandkanten und Verkleben zu einer Naht, wobei ein geschlossener rohrförmiger Körper (vgl. F i g. 7) entsteht.Fig. 3), then one edge of the paper strip arrives in front of the side spray nozzle (see Fig. 4) where this edge is covered with adhesive. As soon the point of the section V-V has been reached, i.e. the point where the circular ring guide is the two edges of the paper strip are already facing each other but kept at a certain distance by the circular ring guide. At the point of the section VI-VI, where the pressure rollers are arranged, the compression then takes place the tape edges and gluing into a seam, being a closed tubular Body (see Fig. 7) is created.
Unmittelbar danach gelangt dieses Papierrohr in den Bereich der Spritzdüse 3, aus welcher ein Kunststoffschlauch austritt, der sich fest an die Innenwand des Rohres anlegt und dieses mit einem geschlossenen Kunststoffüberzug kaschiert. Immediately afterwards this paper tube arrives in the area of the spray nozzle 3, from which a plastic tube emerges, which is firmly attached to the inner wall of the Pipe creates and this is covered with a closed plastic coating.
