Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der Schlitten (20) mit einer Vorratsrolle (38) für ein Klebband (37), das zum Aufbringen auf die Ränder der von der Umkleidungsfolle (3) gebildeten Röhre vorgesehen 1st, und mit einer mit Federdruck arbeitenden Andruckrolle (39) ausgerüstet ist.6. Apparatus according to claim 1, characterized in that the carriage (20) with a supply roll (38) for an adhesive tape (37) which is intended to be applied to the edges of the tube formed by the covering film (3) and which is equipped with a pressure roller (39) operating with spring pressure.

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Bekannt 1st durch die FR 14 95 614 eine Vorrichtung, die eine vollständige Isolierung herzustellen gestattet, die konzentrisch zur Rohrleitung 1st und vom Umfang dieser Leitung ausgehend eine Innere Isolierschicht aufweist sowie eine mittlere dlchts Schicht und eine äußere Schicht zur Isolierung und zum Schutz. Bei dieser Vorrichtung bewegt sich ein Schlitten entlang der Rohrleitung. Ein Ring ist fest am Schlitten, auf welchem Zerstäubungspistolen vorgesehen sind für das Material, das die dichte Schicht bilden soll. Ferner sind zwei Karusselsupporte vorgesehen, die die Spulen mit dem Isoliermaterial tragen, derart, daß beim Fortschreiten des Schlittens zwei schraubenförmige Bandwicklungen entstehen mitIs known from FR 14 95 614 a device, which allows complete insulation to be produced concentric to the pipeline 1st and starting from the circumference of this line has an inner insulating layer as well as a middle layer and an outer one Layer for insulation and protection. In this device, a slide moves along the pipeline. A ring is fixed to the slide on which atomizing guns are provided for the material that should form the dense layer. Furthermore, two carousel supports are provided, which carry the coils with the insulating material, in such a way that when the carriage advances two helical tape windings are created with it Schlitten,Sleds,

Die Fig. 2 zeigt eine Vorrichtung, mit der man auf der Rohrleitung eine Wärmeisolierung bildet durch Expandieren eines thermoplastischen Harzes, das man in einer Form 9 schäumen läßt, die auf der Rohrleitung gleitet zugleich mit der Anordnung der Rolle 4 und der Einlaufrinne 6.Fig. 2 shows a device with which one on the Thermal insulation is formed by expanding a thermoplastic resin that is incorporated into a pipe Form 9 can foam, which slides on the pipeline at the same time with the arrangement of the roller 4 and the inlet channel 6th

Das flüssige Harz wird bei 10 und 11 mit der Rohrleitung In Berührung gebracht. In der Zone 12 beginnt es zu expandieren; seine Expansion ist vollständig beendet bei 13, und es ist schon halb hart. Bei 14 ist das expandierte Harz genügend starr, um mit der Umkleidungsfolie bedeckt werden zu können.The liquid resin is at 10 and 11 with the pipeline Brought in touch. In zone 12 it begins to expand; its expansion is completely finished at 13, and it's already half hard. At 14 the expanded resin is sufficiently rigid to adhere to the liner to be covered.

Bei der in Fig. 3 dargestellten Variante findet die Expansion der Harzes unmittelbar an der Stelle statt, wo die Umkleidung gebildet wird. Das flüssige Harz wird zugeführt bei 15, bei 16 ist es im kremigen Zustand, lind bei 17 beginnt es zu expandieren. Das Harz 1st vollständig expandiert bei 18 und füllt den Zwischenraum zwischen der Rohrleitung 1 und der gebildeten Röhre 19 aus. In diesem Falle dient die Einlaufrinne 6 einerseits zur BiI-dung der Bekleidungsröhre 19 und andererseits zur Herstellung des notwendigen mechanischen Widerstandes zur Aufnahme des Druckes von der Expansion des Schaumes.In the variant shown in Fig. 3, the expansion of the resin takes place directly at the point where the casing is formed. The liquid resin is fed in at 15, at 16 it is in a creamy state, lind at 17 it begins to expand. The resin is fully expanded at 18 and fills the gap between the pipe 1 and the tube 19 formed. In this case, the inlet channel 6 serves on the one hand for formation the clothing tube 19 and on the other hand to produce the necessary mechanical resistance to absorb the pressure from the expansion of the foam.

Die In Fig. 4 dargestellte Vorrichtung zur kontinuierlichen Herstellung der Wärmeisolierung 2 und der äußeren Umkleidung umfaßt einen Schlitten 20, der mit Laufrollen 21 bis 22 versehen 1st, die in Berührung mit der Rohrleitung 1 sind.

Das Chassis 25 des Motors 1st auf dem Schlitten montiert unter Zwischenschaltung von Schraubenhalterungen 26, die die Regelung seiner Stellung in der Höhe entsprechend dem Durchmesser der Rohrleitung 1 gestatten. Zu demselben Zweck sind die unteren Rollen 22 ihrerseits auf regelbaren Halterungen 27 montiert, die eine Veränderung ihrer Stellung zulassen.The device shown in Fig. 4 for continuous Manufacture of the thermal insulation 2 and the outer cladding comprises a carriage 20 with rollers 21 to 22 are provided, which are in contact with the pipeline 1. This sled is self-propelled and has a motor 23 which drives one of the rollers 21 with an intermediate gear 24. The chassis 25 of the motor is mounted on the slide with the interposition of screw brackets 26, which the Allow control of its position in height according to the diameter of the pipe 1. To the same Purpose, the lower rollers 22 are in turn mounted on adjustable brackets 27 that can change their Allow position.

Auf dem Schlitten 20 ist eine rotierende Scheibe 28 montiert, die Rollen 29 mit isolierendem Band 30 tragen. Diese Scheibe wird angetrieben durch den Motor 23 unter Zwischenschaltung einer Transmission 31, die an ihrem Ausgang ein Ritzel aufweist, das in Eingriff 1st mit einem innen verzahnten Kranz an der Scheibe.A rotating disk 28, which carries rollers 29 with insulating tape 30, is mounted on the carriage 20. This disc is driven by the motor 23 with the interposition of a transmission 31, which is attached to her Output has a pinion which meshes with an internally toothed ring on the disc.

Die Rolle 4 mit der Folie 3, die die Bekleidung der wärmeisolierten Rohrleitung bilden soll, ist auf dem Schlitten 20 montiert. Die Folie 3 läuft zwischen Führungsrollen 32 bis 33 durch und wird in die der Führung dienende Einlaufrinne 6 eingeleitet, die an dem Schlitten mittels angelenkter Stangen 34, 35, 36 befestigt ist. Durch kontinuierliche Weiterbewegung auf der Rohrleitung 1 bewirkt der Schlitten 20 zugleich die Bildung der Wärmeisolierung 2 und die Bildung der äußeren Umkleidung 19. Ein von einer Rolle 38 kommendes KJebband 37 wird auf die Ränder der Umkleidung aufgebracht mittels einer Rolle 39, wobei der Support 40 für die Rolle 38 und die Andruckrolle 39 an der Einlaufrinne 6 befestigt sind. Es ist eine Feder 41 0. dgl. vorgesehen, um die Rolle 39 gegen die Röhre zu drücken.The roll 4 with the film 3, which is to form the cladding of the heat-insulated pipeline, is mounted on the slide 20. The film 3 runs through between guide rollers 32 to 33 and is introduced into the inlet channel 6 which is used for guidance and which is attached to the carriage by means of articulated rods 34, 35, 36 . By continuously moving on the pipeline 1, the carriage 20 simultaneously causes the formation of the thermal insulation 2 and the formation of the outer cladding 19. A KJebband 37 coming from a roll 38 is applied to the edges of the cladding by means of a roller 39, the support 40 for the roller 38 and the pressure roller 39 are attached to the inlet channel 6. A spring 41, the like, is provided to press the roller 39 against the tube.
