Glad to get a little of the Ehrhardt Lauf sand sorted. The idea began in the U.S. of A. @ the Sprial Weld Tube Company in East Orange near New York. They derived their idea from pattern welded tube technology( der Flintenläufe, der Damastläufe ). Then Ehrhardt imported the idea / technology to Zella Sankt Blasii & improved it.

>>......Die Fabrikation der gewundenen sogen. spiralgeschweissten Rohre hat ihre Anregung in der Anfertigung der Flintenläufe, der Damastläufe erhalten, welche aus Schweisseisen- und Puddelstahldraht gewunden, in Holzkohlenfeuer zur Schweisshitze gebracht und über einem Dorn durch einen Rohrhammer, einen schnellgehenden Schwanzhammer geschweisst wurden. Vom Jahre 1877 bis 1878 baute Roob eine Maschine, welche 1886 in Betrieb kam, ohne befriedigende Ergebnisse zu liefern. 1886 wurde in East Orange bei New-York von der Spiral-Weld-Tube Co. ein grösseres Werk zur Fabrikation spiralgeschweisster Rohre nach Roob's Verfahren angelegt.......<<

Cheers,
