Abstract

215,775. Deutsche Maschinenfabrik Akt.-Ges. May 11, 1923, [Convention date]. Cupping.-Relates to a machine for drawing a hollow body e on a mandrel b by forcing it through a number of dies a and consists in so arranging the traversing gear that the member thereof connected to the mandrel is under tension during the operation. This member may comprise an endless chain or a rack d extending from the cross-head c in the same direction as, and parallel to, the mandrel.
