Patent

CA 2283881

The invention relates to the manufacture of a tire (10) in a bladderless tire mold (12) that incorporates sealing rings (16, 18, 70) that enable the tire (10) to be easily and quickly installed within the tire mold (12) so that the pressurized gas or fluid used to inflate and vulcanize the tire (10) does not leak around the tire bead sections (44, 46) of the tire (10) and escape into the mold cavity (60). An improved method of mounting the tire (10) into the bladderless tire mold (12) allows the tire (10) to be quickly and easily loaded in and unloaded from the tire mold (12) without the need of moving any mold parts into or out of the space between the tire bead sections (44, 46).

L'invention concerne la fabrication d'un pneu (10) dans un moule (12) pour pneus sans vessie qui incorpore des bagues (16, 18, 70) d'étanchéité permettant au pneu (10) d'être facilement et rapidement installé dans le moule (12) pour pneus de sorte que le gaz ou le fluide sous pression utilisé pour gonfler et vulcaniser le pneu (10) ne s'échappe pas par les talons (44, 46) du pneu pour passer dans la cavité (60) de moulage. Grâce à un procédé amélioré de montage du pneu (10) dans le moule (12) pour pneus sans vessie, le pneu (10) peut être placé dans ledit moule (12) et retiré de celui-ci rapidement et facilement sans qu'il soit nécessaire de sortir des parties du moule hors de l'espace entre les talons (44, 46) du pneu ou de les y rentrer.
