ABSTRACT:
An apparatus for continuously sizing, preforming or forming metal objects includes a plurality of molds arranged in a substantially vertical column and which collectively define a mold cavity. Each mold is separable into at least two mold sections. A retaining mechanism retains the molds in the vertical column. A first and second screw arm assembly separates the bottom mold into sections and removes the mold sections from the bottom of the mold with a horizontally operable screw arm mechanism. The arm assemblies then move the mold sections from a bottom position to an uppermost position with a vertically movable screw arm mechanism. The horizontally movable screw arm mechanism then moves the mold sections to an uppermost position on the vertical mold column to form a top mold.
