Tile edge systems and methods
View Patent ↗Disclosed herein are tiles, systems, and methods related to manufacturing bullnose or other non-straight edge tiles. The tiles can comprise a non-straight edge with one or more printed layers. The printed layers can comprise radiation curable inks or other fast-drying coatings. Upon exposure to a curing station, the layers cure quickly. This provides a printed and cured surface that very closely matches the rest of the tile. The tiles, systems, and methods disclosed herein can be of higher quality and can involve more efficient manufacturing than existing tiles, systems, and methods.
1. A method of manufacturing a bullnose tile, comprising:
providing a field tile, wherein said field tile is a fired ceramic tile comprising a base and a decoration;
transforming the field tile by cutting and then rounding off a longitudinal edge to form a bullnose edge;
coating at least one of a radiation curable base coat or a tie coat on the bullnose edge and curing the base coat or tie coat;
printing a decorative coat comprising print media on the cured base coat or cured tie coat on the bullnose edge and curing the print media; and
coating a radiation curable protective coat on the cured print media on the bullnose edge and curing the protective coat to provide the bullnose tile.
2. The method of claim 1 , wherein the print media comprises radiation curable ink.
3. The method of claim 2 , wherein curing the print media comprises exposing the print media to a radiation lamp.
4. The method of claim 1 , further comprising wet cutting the field tile to form the bullnose edge, drying after wet cutting, and sorting and packaging the bullnose tile after curing the protective coat.
5. The method of claim 4 , wherein the field tile is transported on an in-line conveyor system during wet cutting, drying, printing, curing the print media, and curing the protective coat.
6. The method of claim 1 , wherein said rounding off reveals a portion of the base of the field tile at the bullnose edge.
7. The method of claim 1 , wherein printing a decorative coat comprises printing with print heads that are disposed at an angle to a top surface of the tile having the cured base coat or cured tie coat on the bullnose edge.
