  Next, a method for producing a floor decorative material according to the present invention will be described. Here, the groove processing of the surface material 20 of the floor decorative material 1 will be particularly described.

  All the manufacturing steps of the surface material 20 can be performed in-line. That is, the surface material 20 is press-molded into a plate-like body having a square shape in plan view by filling and clamping with a molding die, demolding, and taking out a molded product. Subsequently, an engaging groove 21 is provided on the side surface of the molded body of the surface material 20 on the same line.

  The engaging groove 21 is formed by performing groove processing in two stages using a disc-shaped cutting cutter set in a production line at a factory. For the groove processing of the engaging groove 21, it is preferable to use diamond cutters 4a and 4b capable of cutting a material having high hardness. The general shape of the diamond cutters 4a and 4b is such that a diamond layer is provided on the outer periphery of a thin circular disk, and the diamond layer is slightly thicker than the thickness of the disk.

  As shown in FIG. 4, first, the engagement groove 21 is first cut into a substantially U-shaped cross section using a diamond cutter 4a having a convex tip section of the cutting blade. By this primary cutting, a groove having a substantially U-shaped cross section can be formed along the side surface of the molded body of the surface material 20 on, for example, two opposing side surfaces.

  Next, as shown in FIG. 5, the engaging groove 21 is subjected to secondary cutting using a diamond cutter 4b having a substantially triangular tip section. In the secondary cutting process, the tapered portion of the inner upper surface 21b of the engagement groove 21 is cut. At this time, in the substantially U-shaped engaging groove 21 formed by primary cutting, the inner and lower surfaces 21a are not cut, and the grooves are cut so that only the inner upper surface 21b is cut.

  The molded body of the surface material 20 thus grooved is heated at a high temperature and fired. Thereby, the desired surface material 20 which has the said recessed groove-shaped engagement grooves 21 and 21 can be obtained.

  In the two-step grooving of the engaging groove 21, the thickness of the cutting blades of the diamond cutters 4a and 4b is selected in accordance with the thickness of the engaging groove 21 to be formed, so that one grooving is performed. By the operation, the primary cutting of the single engagement groove 21 along the side surface of the surface material 20 can be easily performed.

  In addition to the porcelain tiles described above, the surface material 20 can be manufactured by a similar dry-type molding process using a porcelain tile, a ceramic tile, and the like, and can be molded and fired in-line. It can be produced efficiently at low cost.

  In addition, since the engaging groove 21 of the surface material 20 has a concave groove-like cross-sectional shape as described above and is formed by two-stage cutting, defects such as chipping can be greatly reduced. Thus, the yield can be improved.

  The surface material 20 formed through the above steps is gripped by an appropriate suction device or the like and fitted into the frame body 10, and the molded frame body 10 is completely cooled to engage with the engagement convex portion 14. By engaging with the groove 21, the floor decorative material 1 in which the surface material 20 is stably fixed to the frame body 10 can be obtained.
