摘要： A mold comprises a first shell and a second shell that are suitable, in the closed position, for imparting a shape to a part that is to be molded in the mold, a main axis A being perpendicular to the main plane in which the first shell and the second shell extend. The mold further comprises at least one slide that is situated between the first shell and the second shell and that is in contact with the first shell and the second shell when the mold is in the closed position, and that is to come into contact with the molded part, the or each slide presenting a first face that constitutes its interface with the first shell, the first face presenting a primary direction along which the slide is suitable for sliding along the first face when the mold is in the open position.

摘要： Method for forming a riblet on a component and riblet mould. This invention relates to a method for forming a riblet (3) on a component (1), characterised in that it comprises steps of: printing (106) the riblet on the component (1), comprising applying a film (1) comprising a riblet imprint (6) on the component (1), and peeling (108) the film (4) so as to separate the riblet imprint (6) from the component (1), after printing (106). This invention also relates to a riblet mould (3), the mould comprising a film (4) in which a riblet imprint (6) is formed, the film (4) being adapted to be separated from a component (1) on which a riblet (3) has been printed by means of the riblet mould (3), by peeling the film (4).
