  Vorrichtung zur Herstellung von Doppelrohren aus Metallblech.   Li   
 EMI1.2 
 l)Die vorliegende Erfindung betrifft eine Vorrichtung zur Ausführung des durch die deutsche Patentschrift Nr. 98652 bekannt gewordenen Verfahrens, nach welchem Doppelrohrc aus Metallblech in der Weise hergestellt werden können, dass das letztere von zwei einander gegenüberliegenden Rändern aus nach entgegengesetzten Richtungen spiralförmig aufgowunden wird, worauf die aneinander grenzenden Lagen des Bleches durch   Vorlöthell   mit einander   verbunden werden.

   Während   jedoch gemäss der genannten Patentschrift zuerst die eine   Bluchhälfte   nach der einen und sodann die andere   Blechhälfte nach   der andern Richtung spiralförmig aufgerollt wird, bis beide entstehenden   Blochrohre   so dicht wie   möglich   aneinander liegen, soll das beiderseitige Aufrollen des Metallbleches in einem   Arbeitsvorgänge ermöglicht werden.   Zu diesem Zwecke finden zwei übereinander gelagerte Dorne Anwendung, welche je einen der beiden einander gegenüberliegenden   Ränder des   Motallblechos mit in ihrem   Umfange   angebrachten Längsnuthen erfassen und hierauf gleichzeitig in derartige Umdrehung versetzt werden können,

   dass das Blech sich von seine beiden   Rändern   aus in entgegengesetzten Richtungen auf die beiden Dorne aufrollt,

  Device for the production of double tubes from sheet metal. Li
 EMI1.2
 l) The present invention relates to a device for carrying out the method made known by German patent specification No. 98652, according to which double tubes can be produced from sheet metal in such a way that the latter is wound up spirally from two opposite edges in opposite directions, whereupon the adjacent layers of the sheet are connected to each other by pre-soldering light.

   However, according to the cited patent, while first one half of the sheet metal is rolled up in one direction and then the other half of the sheet metal in the other direction, until the two resulting Bloch tubes are as close as possible to one another, the metal sheet can be rolled up on both sides in one operation. For this purpose, two superposed mandrels are used, which each grasp one of the two opposing edges of the metal sheet metal with longitudinal grooves applied around their circumference and can then be set in such rotation at the same time,

   that the sheet metal rolls up from its two edges in opposite directions onto the two mandrels,
The new device is shown in FIGS. 1 and 2 of the accompanying drawings

 that both thorns a a threaten each other in the same direction. As a result, the metal sheet m is rolled up by both mandrels at the same time, the
