Abstract:
A method for the surface treatment of clay, ceramic or cementitious articles, especially roofing tiles, comprising providing a hardenable, water-containing mass (1) shaped in the form of the article, then covering an exposed surface area of the article with a vibratable plate (3), for example of steel or acrylic, having an upper-surface and a smooth under-surface, such that the latter is in intimate contact with and conforms to the contours of that surface area of the article, thereby providing a plate-covered area of the article, vibrating the plate-covered area of the article, for example via a vibrator head (6), such that vibration is transmitted through the plate, to the surface of the article, and either removing the plate then hardening the article, or at least partially hardening the article with the plate in place.
