(57) Abstract:
(EN): A tread for retreading tires, having an external face (21) provided with the usual grooves (23) and an internal face (22) to be seated and adhered, usually by vulcanization, to the convex external face (11) of a tire carcass (10), from which the compound of the original tread has been totally abraded, said tread (20) presenting a thickness that varies throughout the width thereof, having its internal face (22) defined in a concave arc, with the radius of curvature corresponding to that of the external face (11) of the tire carcass (10) and with its external face (21) being flat or slightly convex, with the radius of curvature substantially larger than that of its internal face (22).
(FR): Cette semelle pour rechapage de pneumatiques comporte une face extérieure (21) dans laquelle sont ménagés les creux habituels (23) ainsi qu'une face intérieure (22) à faire adhérer, d'ordinaire par vulcanisation, à la face extérieure convexe (11) de la carcasse du pneumatique (10), la matière ayant composé le pneumatique d'origine ayant été entièrement abrasée. L'épaisseur de cette semelle (20) varie sur toute sa largeur et sa face intérieure (22) forme un arc concave dont le rayon correspond à celui de la face extérieure (11) de la carcasse, la face extérieure (21) étant plate ou légèrement convexe et ayant un rayon de courbure sensiblement plus important que celui de la face intérieure (22).
