    (54) Inorganic cured shape and method of producing the same


    (57) In the production of inorganic cured shapes for use as roof­ing, exterior walls, and interior walls, an inorganic molded material is formed and patterned using an air-permeable mold­ing die (29, 28) to improve their releasability.The molded material (30) is pressure molded using a molding die having a projection (34) which forms a groove. Thereafter, these shapes are cut along the groove by a cutter (31). If a slit portion is formed in the inorganic molded material, a cutter or a cutter blade unit having a pusher cuts or punches the in­organic molded material to produce the shapes having cutting grooves on the surface, whereby the shapes are easy to handle and have good workability.
