ABSTRACT:
The invention concerns a method for the flush embedding of an inlay in the surface, particularly the curved surface, of a molded main piece.
This method is characterized by the fact that, before the mold is filled with the material constituting the main piece, the inlay (1) is introduced into the mold (4) and is placed in the proper relative position on the article (3) that is to be made, the inlay (1) is held in this position, and the inlay (1) is forcibly deformed so as to have a shape complementary to that of the mold (4).
The invention is applied to the manufacture of molded pieces.
