An improved apparatus for forming drawn and ironed containers from metal blanks. A duplex drive mechanism rotated by a single motive device translates rotary into recipricatory motion by means of pivoted levers, transmitting it to the reciprocating carriages of a pair of juxtaposed machines through linkages having disengagable latches so that one machine may be disconnected while the other remains in operation. A pair of disc-like cams are provided, one operating a stripper punch disposed within an ironing ram used to advance metal blanks through successively smaller forming dies. The other cam is used to control the operation of a redraw die disposed about the ironing ram and which acts in concert with the ram to redraw blanks fed into the machine. Each carriage is articulated, force being applied to a rear portion of the carriage through linkages coupled to a source of motive power. A toggle linkage for operating the stripper punch is also carried by the rearward portion of the carriage. The ironing ram itself is carried by the forward portion of the carriage, the articulation joint in the carriage serving to isolate the forward portion from lateral forces applied to the rear portion.
