Abstract: A method of stably producing a ceramic sheet with good quality, where the tip portions of convex parts constituting numerous wrinkles on the surface of the ceramic sheet are not in contact with each other, and concave parts are open. To produce the ceramic sheet, clay is placed on the upper surface of a stretched rubber sheet, and the upper surface of the clay is covered by a surface layer made from a material that burns when the clay is baked. The rubber sheet is contracted to form wrinkles on the upper surface of the clay and the surface layer. The clay is baked and the surface layer is made to disappear by burning to obtain the ceramic sheet. Thus, the surface layer prevents the tips of the convex parts constituting the wrinkles from being in direct contact with each other.

Abstract: For forming a ready-to-bake, endless dough ring, a dough piece is first round kneaded in a round-kneading station and then fermented in a fermenting station. In a pressure station, flattening pressure is exerted on two sides of the dough piece for a flat round piece to produce. After a relaxation interval, an inside hole is punched into the relaxed dough piece in a punching station, with a dough ring being obtained. The individual stations of a corresponding dough treatment system are connected to each other by means of a conveyor. Then secondary fermenting of the shaped dough ring takes place, which is followed by baking of a ring article. The result is an efficient method of forming a ready-to-bake, endless dough ring. Producing the baked ring article can be completely automated.
