As a kind of tile,
There are single-sided tiles that have a curved wooden edge. This single beveled tile is used, for example, at the nose of a staircase as shown in FIG. 4, or at an outside corner of a building (not shown). In FIG. 4, reference numeral 10 denotes a single-sided tile, and reference numeral 11 denotes a square tile.

When such a single-sided tile is to be decorated by a roller printer as shown in FIG. 3, the decoration is performed on the upper surface of the tile 10, but the decoration is performed on the curved wooden end surface 10a. Not done. The wooden end surface 10a formed of this curved surface is a surface that is exposed to the outside after the tiling work, so that if the wooden end surface 10a is not decorated, the design of the upper surface of the tile 10 and the wooden end surface 10a The design is different. If the design of the wood end surface 10a is different, the artificial image printed on the upper surface becomes stronger, and the artificial image becomes more natural even when a natural stone-like decoration such as marble is applied to the upper surface. It is felt, and the natural stone-like patterning effect is low.

The present invention provides a method for decorating a single-sided tile, which can continuously apply the same decoration to the upper surface (front side) of a single-sided tile as a curved or inclined wooden surface. The purpose is to do.

[0013]

According to the method of decorating a single-sided tile of the present invention, a tile is placed on an upper surface of a moving body, and the tile is brought into contact with the outer peripheral surface of a printing roller while moving the moving body. In the method of decorating a tile for printing on the tile, the tile is a single-chamfered tile having a chamfered shape on one side, and the moving body is provided with a pedestal made of an elastic material whose leading side in the moving direction is higher. The tile is placed on the pedestal such that the one side is the top side, and the roller also performs printing on the tree end surface of the one side of the tile by the roller. Is what you do.

According to the method for decorating a single-chamfered tile, the single-chamfered tile that has been moved on the pedestal made of an elastic material on the moving body comes into contact with the roller when its curved or inclined wooden end face comes into contact with the roller. The end of the tree is also printed, and then the top of the tile is also printed by the rollers. Therefore, not only the upper surface (front surface) of the single beveled tile but also the wooden end surface formed of a curved surface or an inclined surface is decorated with a pattern that is continuous with the upper surface (front surface).

The single-chamfered tile according to the present invention is very suitable for application when one wooden edge is a curved surface, but is also applicable to a single-chamfered tile where one wooden edge is an inclined surface. it can.
