KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. r 130369
KLASSE 7ίκ r 130369
CLASS 7ίκ Die Erfindung betrifft eine Abänderung des Verfahrens nach Patent 124367,. und zwar in der Weise, dais sich dies Verfahren auch zur Herstellung von in der Länge gerippten Röhren (sogen. Serfröhren) verwenden la'l'st, und zwar von solchen, bei welchen die Profilirungen der Wandungen entweder nach aufsen oder nach innen, oder nach aufsen und innen gerichtet sind, oder bei welchen dieselben sich zwischen ■ der inneren und äufseren Wandung des Rohres befinden.The invention relates to a modification of the method according to patent 124367. namely in the way that this process can also be used to manufacture tubes that are ribbed in length (so-called Serfröhren) use la'l'st, namely from those in which the profiles of the Walls either outwards or inwards, or outwards and inwards are, or in which the same are between ■ the inner and outer wall of the pipe are located. Dieselben werden in der im Haupt-Patent beschriebenen Weise hergestellt, nur mit dem Unterschiede, dafs man statt der ebenen Platten, welche dort verwendet werden, solche verwendet, die in ihrer Querrichtung profilirt sind, also z. B. längslaufende aufgesetzte Rippen, Wellen u. s. w. aufweisen.The same are made in the manner described in the main patent, only with the Differences in that instead of the flat plates which are used there, such plates are used, which are profiled in their transverse direction, so z. B. longitudinal attached ribs, Have waves and so on. Diese Platten formt man durch Ziehen durch den Trichter in der beschriebenen Weise zum Rohr und formt über das so gebildete Rohr ein zweites Rohr hinweg; zu dessen Bildung wird ein profilirter Streifen oder aber auch ein' glatter dienen können. Die Rippen des profilirten Streifens können entweder nach aufsen oder nach innen gerichtet sein.These plates are formed by pulling them through the funnel in the manner described for Tube and forms a second tube over the tube thus formed; to its formation a profiled strip or a smooth one can serve. The ribs of the profiled Stripes can be directed either outwards or inwards. Auf beiliegender Zeichnung sind verschiedene nach diesem Verfahren hergestellte Rohre in halb- und ganzfertigem Zustande veranschaulicht. Various pipes manufactured using this process are shown in the accompanying drawing half-finished and fully-finished condition illustrated. Selbstverständlich kann man die Herstellung der Rohre auch in kaltem Zustande vornehmen und die Vereinigung der Wandungen bezw. Nähte durch nachträgliches Walzen u. s. w. in der in Patentschrift 124367 beschriebenen Weise bewirken. Die bei der Verarbeitung benutzten Trichter erhalten zweckmäfsig einen der Pronlirung der Platten entsprechenden Querschnitt, jedoch können auch glatte Trichter Verwendung finden.Of course, the pipes can also be manufactured in a cold state and the union of the walls respectively. Seams by subsequent rolling and so on effect the manner described in patent specification 124367. The ones used in processing Funnels are expediently given a cross-section corresponding to the pronation of the plates, however, smooth funnels can also be used. Patent-A ν SPR υ c 11:
Eine Ausführungsform des Verfahrens zur Herstellung mehrwandiger Rohre nach Patent 124367, dadurch gekennzeichnet, dafs ein, zwei oder mehrere Mantel des Rohres statt aus ebenen Platten aus mit nach innen oder nach aufsen, oder nach innen und aufsen gerichteten längslaufenden Rippen oder ähnlichen Erhebungen versehenen Blechstreifen durch Ziehen im Trichter geformt und an den inneren Mantel angeprefst werden.Patent-A ν SPR υ c 11:
An embodiment of the method for the production of multi-walled pipes according to patent 124367, characterized in that one, two or more jacket of the pipe instead of flat plates of sheet metal strips with inwards or outwards, or inwards and outwards directed longitudinal ribs or similar elevations Draw in the funnel and pressed against the inner jacket.
