ABSTRACT:
A pizza shell forming machine has a bed with a heating unit and an overlying press die unit. Preformed dough balls are supplied to a reciprocating transfer mechanism having confining walls. A pusher moves the dough ball onto the bed when aligned with the die unit. A confining forward wall is movable vertically such that when the ball is located beneath a die unit, the wall is raised for withdrawal. A projecting thin plate is secured forwardly of the wall and moves and discharges it to top surface piercing unit and then into a baking unit. The piercing unit includes a tined wheel overlying a conveyor belt. Hold down rods hold the shell to the belt during piercing. A heating unit is mounted in an opening in the bed. A movable die unit also includes a heating unit to create a baking temperature on the order of 325.degree. F. Die closure is of the order of 1-5,000 psi. Alternatively, a conveyor plate is longitudinally movable through the press for removing a shell. The conveyor plate is mounted for limited vertical movement for movement into engagement with a fixed heating unit. A piercing plate includes a bottom wall with chisel members. A vacuum and air unit picks the formed shell from the conveyor plate piercing the top surface and releasing the shell when the plate is withdrawn.
