A method and an apparatus for contouring the shoulder areas (38) of retreaded tires (54) is disclosed. A cutter (62), preferably having a heated blade (66), is disposed proximate at least one shoulder of a retreaded tire (54). The retreaded tire (54) is then rotated, while the cutter blade (66) is moved into contact with the side wall (16) of the tire (54) proximate the joint between the tire casing (12) and the tread layer (50). A portion of the tire casing (12) and the tread layer (50) is cut away along the entire shoulder area (38) of the retreaded tire (54) to provide an aesthetically pleasing contoured surface extending from the tire casing (12) to the tread layer (50).
L'invention concerne un procédé permettant de façonner la zone de l'épaule (38) des pneus rechapés (54), ainsi que l'appareil associé. On place un outil de coupe (62), portant de préférence une lame chauffée (66), à proximité d'au moins une épaule d'un pneu rechapé (54). On fait ensuite tourner celui-ci, tout en mettant en contact la lame (66) avec le flanc (16) du pneu (54) au niveau de la jonction entre l'enveloppe (12) et la bande de roulement (50). On enlève une partie de l'enveloppe (12) et de la bande de roulement (50) tout le long de la zone de l'épaule (38) du pneu rechapé (54), de façon que la surface profilée reliant l'enveloppe (12) à la bande de roulement (50) soit esthétiquement satisfaisante.
