ABSTRACT:
The invention relates to a method of marking the surface of articles, more particularly but not exclusively with a view to obtaining distinctive signs on non-plane surfaces such as the surface of balls. It is characterized in that the material (8) comprising the sign (2) is molded on a temporary support (11) that is independent of the article, and benchmark means (12) are molded on that same support; in the mold for the article, which is made in at least two portions (14, 15), the temporary support is inserted, which with the aid of the benchmark means (12) is positioned with respect to one (15) of the portions (14, 15) of the mold; from the inside portion (15) of the mold (13), the material which will make the article is injected into the mold, and with the aid of the pressure of this material, the temporary support is locally deformed and presses its outside face (19) against the impression (17) of the portion of the mold that will form the marked surface of the article that carries the sign; the temporary support is removed, and the surface thus exposed is finish-ground. The invention is applicable to the gambling equipment industry.
