Method for bending ceramic tiles
The invention relates to an improved method for bending ceramic tiles. The method comprises the stages of making grooves in the lower surface of the tile in the area of the tile to be bent, filling the grooves obtained on the tile with a filling material compatible with the material of which the tile is made, covering the grooves with a flexible strip of incombustible refractory-material, anchoring the strip to the surface of the tile, heating the area of the tile to be bent up to the softening temperature of the area itself and cooling the modelled tile thus obtained..
