Abstract: A dough forming die assembly for the manufacture of machine-made pizza crusts in cooperation with a pizza pan having a generally circular central portion surrounded by upwardly sloping walls joining a horizontal rim. The dough forming die is mounted to a vertically movable base and provided with a generally planar face portion having a surrounding recessed rim. The outer wall of said rim is provided with a downwardly extending thin lip adapted to engage the upper portion of said sloping walls of said pan. A cylindrical, ring-shaped sealing member is mounted to the base for limited slidable movement relative to said die between a raised position and a lowered position engaging said pan and slideably engages the outer wall of said rim.
