Abstract:
1. A method for producing a profiled bead made of a plastic on a piece, comprising: positioning a flexible mold including a forming face and a flexible support on a support frame, wherein the forming face is supported by the flexible support which has a shape that can vary under pressure of a fluid; fixing the piece with respect to the support frame via rests positioned beneath the piece such that the forming face is not pressed against the piece when the flexible support is not inflated by the fluid; positioning a mating mold on the support frame such that the mating mold is in contact with the support frame and the forming face is not pressed against the mating mold when the flexible support is not inflated by the fluid; after the fixing the piece and the positioning the mating mold, inflating the flexible support with the fluid such that the forming face moves from a position not pressed against the mating mold or the piece to a position in contact with at least a partial portion of an edge region or lateral face region of a surface of the piece and the mating mold to form a cavity in which the plastic is deposited without the mating mold contacting the piece; and depositing, in the cavity, the plastic to be stuck to at least part of a periphery of the surface of the piece not covered by the forming face and defining external dimensions of the profiled bead by the forming face and the mating mold.
