Claims
- 1. An apparatus for baking thin-walled shaped bodies, the apparatus comprising:a baking shaft defining adjacent up and down paths; a respective stack of pairs of cavity-forming baking plates in the shaft at each of the paths; heating means in the shaft for heating the stacks between upper and lower ends thereof; lower transport means for conveying plates from the lower end of the down-path stack to the lower end of the up-path stack; upper transport means for conveying plates from the upper end of the up-path stack to the upper end of the down-path stack; and upper and lower filling and stripping means above the respective upper and lower transport means for depositing a bakable preproduct on the plates and for removing a baked product from the plates.
- 2. The baking apparatus defined in claim 1, further comprisingmeans for locking the plates pair vertically together as they move between the ends of the down-path stack.
- 3. The baking apparatus defined in claim 1 wherein the lower transport means includesa lower conveyor extending from the lower end of the down-path stack to the lower end of the up-path stack, means for picking the plates off the lower end of the down-path stack and thereby lowering the entire down-path stack a step, and for setting the picked-off plates on the lower conveyor for conveyance to below the up-path stack, and means for lifting the plates off the lower conveyor and pressing them against the lower end of the up-path stack so as to raise the entire up-path stack.
- 4. The baking apparatus defined in claim 1 wherein the upper transport means includesan upper conveyor extending from the upper end of the up-path stack to the upper end of the down-path stack, means for transferring plates from the upper end of the up-path stack to the upper conveyor for conveyance to above the down-path stack, and means for transferring the plates from the upper conveyor to the upper end of the down-path stack.
- 5. The baking apparatus defined in claim 1 wherein each baking plate has an upper and a lower surface and upwardly and downwardly projecting rims bounding the respective surfaces, whereby each plate forms an upper half of one mold cavity and a lower half of another mold cavity.
- 6. The baking apparatus defined in claim 1 wherein each baking plate has an inner surface and is formed with a vertically projecting rim bounding the respective inner surface and with an oppositely directed outer surface, whereby the plates can be inverted so that each forms a top or bottom half of a mold cavity and bears with its outer surface in the stack on the outer surface of an adjacent plate.
- 7. The baking apparatus defined in claim 6, further comprisingmeans for locking the plates vertically together as they move between the ends of the stacks.
- 8. The baking apparatus defined in claim 1 wherein the plates are formed with throughgoing passages, the heating means forcing hot gases through the passages in the stacks.
- 9. The baking apparatus defined in claim 8, further comprisingmeans for locking the plates of each pair vertically together as they move between the ends of the stacks.
