ABSTRACT:
An apparatus and method for the high-speed production of seamless metal container bodies is disclosed utilizing a reciprocating ram which forces a relatively shallow metal cup through a die assembly to iron the sidewall of said cup to form an elongated ironed container body, the ram is supported and critically-aligned by at least two stationary guide means along its length and a slide blank means rigidly secured to its rearward end, the slide block means having opposed hydrostatic pressure pads to provide constant critical alignment of the rear end of the ram and prevent misalignment of the ram relative to the die assembly to avoid producing container bodies of overly-inconsistent length.
