Description
Verfahren zum Ziehen von Rohren u. dgl. ohne Dorn. Zusatz Patent 42898o. Gegenstand der vorliegenden Erfindung ist ein Verfahren zum Ziehen von Rohren ohne Dorn und von Stangen gemäß Patent q.28980. :Nach diesem Verfahren wird das Rohr oder die Stange nach Beendigung eines Arbeitsvorganges auf einer doppelt wirkenden Maschine geschwenkt und in entgegengesetzter Richtung weitergezogen.Method of drawing pipes and the like without a mandrel. Additional patent 42898o. The present invention is a method for drawing pipes without Mandrel and rods according to patent q.28980. : After this procedure, the pipe or the rod on a double-acting one after completion of a work process Machine swiveled and pulled on in the opposite direction.
Nach dem neuen Verfahren wird das zu bearbeitende Werkstück an beiden Enden mit einer Ziehangel versehen, so daß ein Schwenken des Rohres überflüssig wird. 'According to the new process, the workpiece to be machined is on both The ends are provided with a pulling lever so that the tube does not need to be swiveled will. '
