Abstract of the Disclosure An apparatus and method is provided for progressively converting each blank of sheet material in a stream of moving blanks into a clamshell assembly having interconnected lid and bottom portions. The apparatus includes a female die assembly having first and second mold cavities, an upstream control system for aligning one portion of each blank at a lid-pressing station defined by the first mold cavity, and a downstream control system for aligning a remaining portion of each blank at a bottom-pressing station defined by the second mold cavity. A male die assembly is provided for simultaneously forming a lid portion in one blank of sheet material and a bottom portion in an adjacent blank of sheet material. In particular, during each pressing cycle, the male die assembly simultaneously presses an initial blank at the bottom-pressing station and a succeeding blank at the lid-pressing station to produce the equivalent of a whole clamshell assembly on a single stroke of the male die assembly. This pressing cycle is repeated upon shifting the pressed blanks to a next downstream position to accomplish progressive conversion of each blank into a clamshell assembly.
