ABSTRACT:
A method and an apparatus for continuously sizing, preforming or forming metal objects include 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 mechanism separates the bottom mold into sections and removes the mold sections and positions the sections on a top mold of the column to form a new top mold. Preferably, the mechanism includes first and second arms which are rotatable between the bottom and the top mold positions and which grasp and move the mold sections from the bottom of the column to the top of the column.
