besondere Vorrichtung nach gehämmert und erhielten darauf den Querschnitt Fig. 10. Die Kanten der Rohre stossen hierbei dicht zusammen, so dass das Lothmateriat in Verbindung mit einem Flussmittel auf die Naht aufgetragen werden konnte, um darauf die Löthung vorzunehmen. Statt die Rohre aus einzelnen, von Tafeln abgeschnittenen Blechstreifen herzustellen, wurden die Rohre auch aus Bandeisen erzeugt, bei welchen jedoch die äusseren Kanten abgeschnitten wurden, da das Bandeisen nicht gleichmässig breit war und infolgedessen auch keine geraden Kanten hatte. Es war nicht möglich, aus unbeschnittenen Band-

Rohren eine gleichmässig runde Form zu geben.
Hierbei war es nöthig, bei jedem einzelnen Rohr an dem einen Ende eine Spitze anzupressen, um das Rohr behufs Ziehens durch das Zieheisen erfassen zu können. Ein anderer Übelstand besgand noch in dem vorhin erwähnten Beschneiden der Bandeisen an beiden Längskanten, indem hierbei ein Materialabfall entstand.

Verfahren zur Herstellung von Rohren aus Bandeisen mit gelötheter Längsnaht, dadurch gekennzeichnet, dass die auf bekannte Weise mittelst Zieheisens hergestellten Rohre auf eine Trommel mit nach einer Schraubenlinie laufenden Rille derart aufgewickelt werden, dass die Naht nach aussen liegt, wobei die nach Verlassen des Zieheisens spreizenden Längskanten der Naht durch Gegendruckrollen zusammengepresst werden, um

special device after hammered and received the cross-section Fig. 10. The edges of the tubes abut tightly so that the soldering material could be applied to the seam in connection with a flux in order to carry out the soldering. Instead of making the pipes from individual sheet metal strips cut off from sheets, the pipes were also made from steel strips, but the outer edges were cut off because the iron strip was not evenly wide and consequently had no straight edges. It was not possible to get out of uncut tape
EMI1.4
To give pipes an evenly round shape.
Here it was necessary to press a point at one end of each individual pipe in order to be able to grasp the pipe in order to be able to pull it through the die. Another inconvenience was the previously mentioned trimming of the band irons on both longitudinal edges, which resulted in material waste.

PATENT CLAIMS:
I. A method for the production of pipes from strip iron with a soldered longitudinal seam, characterized in that the pipes produced in a known manner by means of drawing iron are wound onto a drum with a groove running along a helical line in such a way that the seam is on the outside, the after leaving the Draw iron's spreading longitudinal edges of the seam are pressed together by counter pressure rollers
EMI3.2
Soldering metal becomes liquid and flows into the lower soldering cap.
