Since it is hidden and does not appear on the surface, as a result, only the color of the tile portion 15 in the uneven pattern of the surface 12 of the concrete board 2 is configured. This is because the convex portion 14 of the uneven pattern of the patterned belt 6 is already applied with the paint 8 which constitutes the color of the joint portion 13 in the uneven pattern of the surface 12 of the concrete board 2 by the paint supply roller 19. The paint 8 supplied by the supply spray 20 is
As it will be applied on top of it, the concrete board 2
When it is transferred to the surface 12 of the
