  • Patent number: 6196117
    Abstract: An apparatus for baking thin-walled shaped bodies has a baking shaft defining adjacent up and down paths and a respective stack of pairs of cavity-forming baking plates in the shaft at each of the paths. A heater in the shaft heats the stacks between upper and lower ends thereof. A lower transporter conveys plates from the lower end of the down-path stack to the lower end of the up-path stack and an upper transporter conveys plates from the upper end of the up-path stack to the upper end of the down-path stack. Upper and lower fillers and strippers above the respective upper and lower transporter deposit a bakable preproduct on the plates and for removing a baked product from the plates. The plates are transferred from the downstream end of the lower transporter to the lower end of the up stack which is thus stepped upward, and are transferred from the lower end of the down stack to the upstream end of the lower transporter to step the down stack downward.
