Abstract

An inverted press for producing multiple drawn metal containers combines in one press the functions of cupping and drawing presses. The press includes a blanking and cupping station and several drawing and redrawing stations, disposed one adjacent the other and rendered serially operative by a vertically reciprocable slide assembly. At each stage of operation the material, semifinished article or finished article is under complete control. A method for producing a drawn container by multiple forming and reforming of a drawn article, is also provided.
