KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Das in dem Haupt-Patent beschriebene Verfahren wird derartig abgeändert, dafs man, statt einen Steg oder ein Profileisen auf einen Metallstreifen aufzulegen und dann beide zusammen durch den Trichter zu ziehen, einen Metallstreifen verwendet, an den der oder die Stege direct angewalzt sind. Die Höhe der oder des Steges würde gleich dem Durchmesser des aus den Streifen zu bildenden Rohres gewählt werden müssen.The method described in the main patent is modified in such a way that one instead of placing a bar or a profile iron on a metal strip and then both together to pull through the funnel, a metal strip is used to which the or the Bars are directly rolled on. The height of the web or the web would be equal to the diameter of the tube to be formed from the strips must be selected. Es ist gleichgültig, an welcher Stelle des Streifens der oder die Stege sitzen, derselbe kann an der Kante oder in der Mitte oder auch dazwischen angeordnet sein.It does not matter at which point on the strip the bridge or bars sit, the same can be arranged on the edge or in the middle or in between. Beiliegende Zeichnung stellt mehrere Anordnungen von Rippen auf dem Streifen dar.The accompanying drawing shows several arrangements of ribs on the strip. Fig. ι und 2 zeigen Streifen zur Herstellung von Rohren mit nur einer Scheidewand, Fig. 3 solche, aus denen Rohre mit zwei sich kreuzenden Wänden hergestellt werden können.FIGS. 1 and 2 show strips for the production of pipes with only one partition, FIG. 3 those from which pipes with two intersecting walls can be made. Selbstverständlich kann man nur Röhren mit gerade verlaufenden Zwischenwänden nach dem vorliegenden Verfahren herstellen.Of course, you can only post tubes with straight partition walls the present process. Patent-A ν Spruch:Patent-A ν saying: Eine Ausführungsform des Verfahrens nach Patent 115777, dadurch gekennzeichnet, dafs ein Blechstreifen zum Gestalten des Rohres verwendet wird, der mit einem oder mehreren die Scheidewände im Rohre bildenden Stegen aus einem Stück besteht.An embodiment of the method according to patent 115777, characterized in that a sheet metal strip is used to shape the pipe, which is connected to one or more the partitions in the webs forming the pipe are made of one piece. Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
