Title (EN) PLUG PATCH FOR RADIAL TIRES
(FR) PIECE DE BOUCHON POUR DES PNEUS A CARCASSE RADIALE
Abstract:
(EN) A plug patch (10, 50) for repair of an injury in a radial tire (14) including an elongated patch member (11, 51) fixed to an elongated plug (12, 52) projecting eccentrically from the patch member (11, 51) to provide a substantially elongated end portion (38, 59) adapted to lie flush and be adhesively secured to, the inner tire surface (20), over the tread area (15), the shoulder flex area (16) and a substantial portion of the sidewall (18) of a radial tire (14) when the plug (12, 52) is seated within a hole (40) cut through the injury in the tread area (15) of the tire (14). The patch member (11, 51) is preferably built up of plies (25-28; 55-58) of different lengths, each ply containing parallel tire reinforcing cords (29-32; 61-64), the cords (29, 30; 62, 64) in the longer plies (25, 26; 56, 58) extending longitudinally of the patch member (11, 51), while the cords (31, 32; 63) in some of the shorter plies (27, 28; 57) extend transversely of the patch member (11, 51), to reinforce the tread (15) areas surrounding the plug (12, 52) and to permit the longer plies (25, 26; 56, 58) to extend over the shoulder flex area (16) and the adjacent sidewall (18).
(FR) Pièce de bouchon (10, 50) pour réparer un endommagement d'un pneu à carcasse radiale (14), comportant une pièce allongée (11, 51) fixée à un bouchon allongé (12, 52) saillant excentriquement à partir de la pièce (11, 51) afin de fournir une partie terminale essentiellement allongée (38, 59) conçue pour être de niveau et fixée de manière adhésive avec la surface intérieure du pneu (20), sur la zone de chape (15), la zone de flexion d'épaulement (16) et une partie substantielle de la paroi latérale (18) d'un pneu à carcasse radiale (14) lorsque le bouchon (12, 52) est logé dans un trou (40) coupé à travers l'endommagement dans la zone de chape (15) du pneu (14). La pièce (11, 51) est formée de préférence de plis (25-28; 55-58) de différentes longueurs, chaque pli contenant des câblés parallèles de renfort de pneu (29-32; 61-64), les câblés (29, 30; 62, 64) des plis les plus longs (25, 26; 56, 58) s'étendant longitudinalement par rapport à la pièce (11, 51), alors que les câblés (31, 32; 63) de certains des plis les plus courts (27, 28; 57) s'étendent transversalement par rapport à la pièce (11, 51) afin de renforcer les zones de chape (15) entourant le bouchon (12, 52) et de permettre aux plis les plus longs (25, 26; 56, 58) de s'étendre sur la zone de flexion d'épaulement (16) et la paroi latérale adjacente (18).
