摘要：A system for forming unitary containers from flat metal stock includes a uniquearrangement of both previously known and newly discovered apparatus, including meansfor blanking and cupping the flat metal stock into individual cups; means for drawing andredrawing the cups and bottom profiling them in one machine; and additional means fortrimming, flanging, and beading the containers thus drawn. The system and methodinclude, among other things, the utilization of apparatus which permits drawing,redrawing, and bottom profiling to take place in one press. This is accomplished bycarrying draw, redraw, and bottom profile tooling in a single press and by inserting thecups in the press for the draw operation and them removing them and reinserting themfor the redraw and bottom profile operations. The apparatus which makes it possible toperform the method in this fashion includes draw tooling; a first accumulator/dividertable for feeding cups into the press and into the draw tooling; redraw and bottomprofiling tooling; further apparatus for transferring the drawn cups from the press to asecond accumulator/divider table and back into the press for the redraw and bottomprofile operations. A further unique feature of the present system and apparatus is thedisposition of the draw and redraw tooling within the press in alternating, balanced
condition so that, in cooperation with the second accumulator/divider table, the press isat all times provided with a balanced load.
