ROTARY TROWEL FORMING METHOD FOR CERAMIC WARE PRODUCT

PURPOSE:To form relief pattern on the side being in contact with a rotary trowel surface of a ceramic ware product by using the rotary trowel with a relief section on the trowel surface, allowing the number of rotations of a rotary potter's wheel shaft to coincide with a trowel rotary shaft for forming a product. CONSTITUTION:In the case of a dish-shaped product with projected relief sections on the rear side surface, a product with recessed relief sections corresponding to projected relief sections 10 engraved on said rotary outer trowel surface is manufactured and set on a rotary outer trowel wheel forming machine. Then, the number of rotations of a rotary potter's wheel shaft 2 and a trowel rotary shaft 6 are conformed with and molded, and the recessed relief sections engraved on a rotary outer trowel surface 5 are formed in the form of the projected relief sections 10 on the rear side surface 9 of a dish. In the case the recessed relief sections 10 as the design on an inner side surface 11 is formed, the corresponding recessed relief sections are engraved on the rotary inner trowel surface, set in the rotary inner trowel wheel molding machine and molded similarly as above-said. The number of rotations is different according to the size and shape of a molded product, and can be selected properly in the range of 300-420rpm, and in case of inner trowel method, the same can be selected in the range of 550-600rpm.
