ABSTRACT:
A method and apparatus for forming nestable two-piece containers includes forming a cup from a metal blank; redrawing the cup thus formed to approximately one-half its final height while imparting a tapered sidewall thereto by use of a tapered die center; redrawing the container thus formed to its full height while continuing the taper by use of a second tapered die center while simultaneously profiling the bottom of the container thus drawn. The apparatus includes at least two redraw stations, each including a tapered redraw die center and corresponding die. The second of said stations also includes bottom profiling tooling.
