Abstract

327,928. M³ller, G., and Rheinische Metallwaaren-und Maschinenfabrik. July 24, 1929. Drawing; mandrels.-A hollow billet b with flanged end placed in a long die c is drawn out stepby-step into a tube by forcing a mandrel e through it, the die c then being moved up over an unworked part of the billet and the mandrel being forced further down to draw out the next portion and so on. If the completed tube is to be still further drawn, the process is repeated with a larger headed mandrel. Specification 23373/11 is referred to.
