Abstract

L'invention concerne un procédé et un appareil pour confectionner une ceinture circonférentielle pour un pneu ceinturé Le procédé consiste à confectionner la ceinture sur une forme 10 constituée par un ensemble de segments extensibles 12 ayant un contour incurvé qui correspond au contour du sommet de la carcasse du pneu Le procédé permet de réaliser une ceinture qui est complètement ou presque complètement exempte des contraintes entre nappes qui étaient jusqu'à présent engendrées lorsqu'une ceinture cylindrique était appliquée sur la carcasse puis adaptée au contour du sommet de cette dernière.The invention relates to a method and apparatus for making a circumferential belt for a belted tire. The method comprises making the belt on a form 10 constituted by a set of extensible segments 12 having a curved contour which corresponds to the contour of the crown of the carcass of the tire The method makes it possible to produce a belt which is completely or almost completely free from the constraints between the plies which were heretofore generated when a cylindrical belt was applied to the carcass and then adapted to the contour of the crown of the latter.
