A plurality of grooves 116 extending in a direction perpendicular to the bent portion 114 are arranged and formed for the purpose of increasing the adhesion force during tile construction. In order to form this groove 116, a rubber piece extending in a direction perpendicular to the feed direction of the raw material supply body is usually attached to the upper or lower mold in a protruding state, and this rubber piece allows the tile to be formed. When pressure molding the groove 116, the groove 116 is molded at the same time.

合を生じていた。(Problem to be Solved by the Invention) However, when the accessory tile 100 is molded using such a molding device, there is less interference between the filling amount of the raw material at the front end and the vicinity thereof in the feeding direction of the raw material supply body. For this reason, when the raw material is compressed, the density of the raw material decreases in the same part, and when the molded product is fired, the amount of shrinkage becomes uneven, which causes the tile to be deformed or sized incorrectly. A problem was occurring.

る。(Means for solving the problem) The molding device of the present invention was devised to solve the above problem, and its gist is that powder is placed inside a container-shaped raw material supply body. The powder raw material is fed into the cavity of the lower mold from the downward opening while feeding the raw material supply body along the upper surface of the lower mold, and the supplied powder raw material is fed into the cavity of the lower mold. The back surface of the tile is compressed by a mold and a lower mold to form a tile in a predetermined shape, and the back surface of the tile is In a back grooved tile forming apparatus for forming a back groove, the protrusion height of at least one of the protrusions located furthest forward in the feed direction of the raw material supply body is set higher than that of the other protrusions. This is also due to the high price.

る。(Action and effect of the invention) The powder raw material is compressed by the molding device of the present invention,
When forming a tile, even if the amount of raw material filled in the tile forming cavity is slightly reduced at the front end of the raw material supply body in the feed direction and the vicinity thereof, the back groove of the tile molded body corresponding to the same area The raw material compression ratio of the section can be made equal to that of the other back groove sections. This is because the protrusion height of the protrusion portion on the most forward side in the feed direction of the raw material supply body is increased.
