  Verfahren zur Herstellung längsgerippter Rohre. 



   Das vorliegende Verfahren ist eine Abänderung des im Stamm-Patent Nr.   7916   beschriebenen Verfahrens und besteht darin, dass man für alle oder auch nur für einzelne der zu verarbeitenden Platten solche wählt, die in der Querrichtung profiliert sind. Je nachdem man die Platten so biegt, dass die Rippen, Wellen u. s. w. nach innen oder aussen, oder auch nach innen und aussen gerichtet   sind, erhält   man Rohre der mannigfaltigsten Formen. 



   Auf umstehender Zeichnung ist in : Fig. 1 die Herstellung eines solchen Rohres in den verschiedenen Stadien veranschaulicht ; Fig. 2-7 zeigen verschiedene mögliche Aus-   fuhrungsformen.   



   Eine mit aufgesetzten Längsrippen b versehen Platte a wird in bekannter Weise 2.   B. durch   Ziehen durch den Trichter zum Rohr c geformt. Dieses legt man, mit der 
 EMI1.1 
 beschriebenen Weise um c herum zum Rohr, wobei gleichzeitig die Mäntel miteinander   verschweisst werden. Man erhält auf   diese Weise ein doppelwandiges Rohr e, dessen Innenseite mit längslaufenden Rippen b besetzt ist. 



   Fig. 2 zeigt ein   Doppelwandrohr   mit nach aussen gerichteten Längsrippen, welches erhalten wade, indem man ein fertiges oder   unfertiges   glattes Rohr f auf die glatte Seite einer mit dreikantigen Rippen   9   versehenen Platte h auflegte und das ganze durch den Trichter zog. Beim Bearbeiten der Platten mit. nach aussen gerichteten Rippen bedient man sich   zweckmässig eines entsprechend profilierten Trichters.   



   In Fig. 3 sind beide   Rohrmäntel   mit Rippen besetzt, und zwar kehren die Mäntel ihre ebenen Seiten gegeneinander, während die Ausführungsformen Fig.   R   die profilierten

  Process for the production of longitudinally ribbed tubes.



   The present method is a modification of the method described in the parent patent no. 7916 and consists in choosing for all or just some of the panels to be processed that are profiled in the transverse direction. Depending on how you bend the plates so that the ribs, waves, etc. s. w. directed inwards or outwards, or inwards and outwards, one obtains tubes of the most varied shapes.



   In the accompanying drawing: FIG. 1 illustrates the production of such a pipe in the various stages; Fig. 2-7 show various possible embodiments.



   A plate a provided with attached longitudinal ribs b is formed in a known manner 2. B. by pulling through the funnel to form tube c. This one sets with the
 EMI1.1
 described way around c to the pipe, at the same time the jackets are welded together. In this way, a double-walled tube e is obtained, the inside of which is covered with longitudinal ribs b.



   Fig. 2 shows a double-walled tube with outwardly directed longitudinal ribs, which is obtained by placing a finished or unfinished smooth tube f on the smooth side of a plate h provided with triangular ribs 9 and pulling the whole thing through the funnel. When processing the panels with. outwardly directed ribs it is advisable to use an appropriately profiled funnel.



   In Fig. 3, both pipe jackets are studded with ribs, namely the jackets turn their flat sides against each other, while the embodiments of Fig. R the profiled
 EMI1.2
 
4 and 5 show combinations of flat and profiled plates, and FIG. 7 shows an exemplary embodiment of a pipe consisting of three jackets.

PATENT-ANSPRUCH: Eine ausführungsform des im Stamm-Patente Nr. 7916 beschriebenen Verfahrens zur Herstellung von Rohren, deren Wandungen aus zwei odor mehr miteinander verschweissten Lagen bestehen, dadurch gekennzeichnet, dass an Stelle eines oder mehrerer glatter, die Mäntel des Rohres bildender Blechstreifen solche mit nach innen oder nach aussen, oder nach innen und aussen gerichteten längslaufenden Rippen oder ähnlichen Erhebungen verwendet werden. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: An embodiment of the process described in the parent patent No. 7916 for the production of pipes, the walls of which consist of two or more layers welded together, characterized in that instead of one or more smooth sheet metal strips forming the jacket of the pipe, those with inward or outwardly, or inwardly and outwardly directed longitudinal ribs or similar elevations can be used. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
