Title (EN) TIRE WITH VARIABLE RIBBON SIZE TREAD AND SYSTEM AND METHOD FOR MAKING SAME
(FR) PNEU À BANDE DE ROULEMENT DE TAILLE DE RUBAN VARIABLE AINSI QUE SYSTÈME ET PROCÉDÉ DE FABRICATION DE CELUI-CI
Abstract:
(EN) A method of manufacturing a tire tread includes extruding a rubber strip and conveying the rubber strip through an opening of a roller die. The opening is defined by an upper die and a lower die, wherein the upper die and lower die contact the rubber strip and define a cross-section of the rubber strip as the rubber strip is conveyed through the opening. The method also includes adjusting a distance between the upper die and the lower die as the rubber strip is conveyed through the opening. The method further includes applying the rubber strip from the roller die onto a receptacle that rotates about a receptacle axis. The method also includes translating the roller die in a first direction parallel to the receptacle axis while applying the rubber strip, thereby forming a spiral of the rubber strip about the receptacle.
(FR) L'invention concerne un procédé de fabrication d'une bande de roulement de pneu consistant à extruder une bande de caoutchouc et transporter la bande de caoutchouc à travers une ouverture d'une matrice de rouleau. L'ouverture est définie par une matrice supérieure et une matrice inférieure, la matrice supérieure et la matrice inférieure entrant en contact avec la bande de caoutchouc et définissant une section transversale de la bande de caoutchouc lorsque la bande de caoutchouc est transportée à travers l'ouverture. Le procédé consiste également à ajuster une distance entre la matrice supérieure et la matrice inférieure lorsque la bande de caoutchouc est transportée à travers l'ouverture. Le procédé consiste en outre à appliquer la bande de caoutchouc à partir de la matrice de rouleau sur un réceptacle qui tourne autour d'un axe de réceptacle. Le procédé consiste également à effectuer une translation de la matrice de rouleau dans une première direction parallèle à l'axe de réceptacle tout en appliquant la bande de caoutchouc, formant ainsi une spirale de la bande de caoutchouc autour du réceptacle.
