った。Conventionally, in order to manufacture long and narrow tiles with a width of 2 square feet, the clay was supplied to the extent that the clay mound was raised in the formwork for pressure molding of the tile raw material, and the clay was applied along the longitudinal direction of the tile raw material. The surface of the molding clay was smoothed by reciprocating the molding clay, and the molding clay was then pressure-molded to obtain a tile green material, and the tile green material twb was formed to produce elongated tiles. .

．． In the next case, after dehydrating and drying the raw materials for Doryakujojuku, using a disintegrator or TFFD-type fret, etc., to crush and pack the clay, the particles of the clay for Akikogata are angular. Due to the shape, one tile raw material is filled in the formwork of the pressure molding machine. TL of the tile output area obtained by! ! The i degree (i.e., the hardness of the tile raw material) increases as it goes from the center of the tile raw material to both ends along the longitudinal direction of the tile raw material, and as a result, the center of the longitudinal side of the elongated tile obtained by firing There was a defect that the part was warped in a drum shape.

As shown in the diagram in a slightly exaggerated manner, a protuberance 1a' of minute height is formed on the upper surface of the central portion in the longitudinal direction, and the curves of the protrusions 1a, la... Both ends of the rear or 1J at least one end are gradually lowered
'I'm standing there. Between the protrusions 1a and la, a recess #lb is formed at both front and rear ends or at least on one side as a gradually deeper recess 1b' shaped like a side boat's bottom, and the bottom surface portion other than both ends of the recess 1b is formed. is formed substantially flat]1. Convex strips 1a on both left and right sides, Kl-j on the outside of la, concave #1jlC11c
is formed in the same manner as the concave groove 1b. Therefore, as shown in FIG. 2 (ARK), such a mold 1 is
The clay supply frame 3 is placed in the upper surface concave l912a of the lower mold 2.
In the frame of 3aK, 5 pieces of clay for molding are supplied from hopper 4,
The clay supply frame 3 is machined in the direction of the arrow A in the 111st direction, and is fed onto the forming W, 1. I7. Then, the clay supply frame 3 is moved back (set #7t).
Move the oyster 3b back along the protruding line 1aK of the mold l so that it rises up as shown in Fig. Clay for molding 5'
After smoothing the surface of the mold 1, move the reverse tokaki 7 along the convex strip 1a of the mold 1 as shown by the dot chain B i in the figure, and smooth the surface of the irregular shape mold 5' and the mold 6. The upper surface is substantially concave and flat. Next, as shown in FIG. 2 (CIK), the upper mold 8'f is lowered to perform pressure molding of the molding jb 5'. As shown in the cross-sectional view, the protrusions 1a, la... of the mold 1 are formed by continuous pressure.
・The upper end of the tile material 9 is pushed out so that it is spread upward, so that the back side of the tile material 9 is shaped like a sea urchin to form a long dovetail leg 9a whose cross section except one end is spread upward. At the time of this pressure forming, even if the front and back sides of the molding clay 5' of the pressurizer are denser than the central part by the operation of the tokaki 3a and 7. , the soil (I
r]tic formed ridge 1 a' (see Fig. 1 (A)), the low-density central part of the molding clay 5' is strongly compressed, and the high-density li1 Since the pressure is applied weaker toward both rear sides than at the center, the density (hardness) of the tile material 9 formed under pressure becomes approximately uniform over the entire surface. When the pressure of the upper mold 8 is released, the expanded state of the protrusions 1a, la, . . . of the mold l returns to its original shape due to its own restoring elastic force. (D) [As shown, the entire side edge of the tile raw material 9 protruding from the mold 1 is pressed by the clay supply frame 3, etc., and is easily removed from the mold 1. In addition, the concavity of mold l @l'b, lb

Formed by pressure forming H7T tile roping fabric 9
1iJ of the lower surface of the foot leg 9a other than the rear end or one end,
Since it is formed into a flat shape, when the tile raw material 9 is fired by placing the dovetail leg on the firing sheath with the dovetail legs facing down, the bottom part of the fired tile will not warp in the longitudinal direction. .
