 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- 
 EMI1.4 
 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.

 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.

 EMI3.1
   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.

 

Claims (1)

2. Eine Abänderung des Verfahrens nach Anspruch 1 dahin, dass das schraubenförmig aufgewunden Rohr so durch das Löthfeuer geführt wird, dass die sämmtlichen Schraubenwindungen an der tiefsten Stelle gleichzeitig sich im Löthfeuer befinden, um so EMI3.3 laufenden Rills von einer Tiefe, welche mindestens gleich ist dem Halbmesser des Rohres in Conbination mit einer oder mehrerer Gegendruckrollen, welche beim Aufwickeln des Rohres die sproizondfu Kanten der Längsnaht zusammenpressen, derart, dass nach Ab- nahme des Rohres von der Trommel die Längsnaht geschlossen bleibt. 2. A modification of the method according to claim 1 such that the helically wound pipe is guided through the soldering fire that all the screw turns at the lowest point are at the same time in the soldering fire, so EMI3.3 running grooves of a depth which is at least equal to the radius of the pipe in combination with one or more counter-pressure rollers, which press the sproizondfu edges of the longitudinal seam together when the pipe is wound, in such a way that the longitudinal seam remains closed after the pipe has been removed from the drum .
