Abstract
Official abstract text for this publication.
A method for manufacturing a tire ( 1 ) comprises a step of positioning a reinforcing ply ( 9 ) in a rubber material having grooves ( 6 a ) such that the reinforcing ply ( 9 ) extends through the grooves ( 6 a ), and of crosslinking the tire ( 1 ) based on uncured rubber material while hot moulding the latter, with the reinforcing ply ( 9 ) being pushed against the bottom of the grooves ( 6 a ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a tire comprising: positioning a reinforcing ply in a rubber material having grooves such that the reinforcing ply extends through the grooves; crosslinking the tire based on uncured rubber material by hot molding the uncured rubber material, with the reinforcing ply being pushed against the bottom of the grooves; manufacturing a carcass based on uncured rubber material; mounting on the carcass a green form of tread based on uncured rubber material comprising the rubber material having the grooves; and mounting on the green form of tread a stiffening layer having uncured rubber material and the reinforcing ply, the reinforcing ply being interposed between the rubber material of the green form of tread and the rubber material of the stiffening layer, wherein the stiffening layer is mounted such that it does not have uncured rubber material vertically in line with the grooves. 2. The method according to claim 1 , wherein the step of mounting the stiffening layer comprises: manufacturing the uncured rubber material of the stiffening layer and the reinforcing ply; mounting the reinforcing ply on the green form of tread; and mounting the uncured rubber material of the stiffening layer on at least a part of the reinforcing ply. 3. The method according to claim 1 , wherein the step of mounting the stiffening layer comprises: manufacturing the uncured rubber material of the stiffening layer and the reinforcing ply; assembling the uncured rubber material of the stiffening layer on at least a part of the reinforcing ply so as to form a composite stiffening layer; and mounting the composite stiffening layer on the green form of tread. 4. The method according to claim 1 , wherein the step of mounting the stiffening layer comprises: manufacturing the uncured rubber material of the stiffening layer and the reinforcing ply; mounting the reinforcing ply on the green form of tread; and mounting the uncured rubber material of the stiffening layer on at least a part of the reinforcing ply by successive winding of strips. 5. The method according to claim 1 , wherein the reinforcing ply has polymer-based fibers. 6. The method according to claim 1 , wherein the step of mounting the green form of tread on the carcass comprises: manufacturing at least one uncured rubber material; and mounting the at least one uncured rubber material on the carcass so as to form the green form of tread. 7. The method according to claim 1 , wherein the step of mounting the green form of tread on the carcass comprises: manufacturing at least one uncured rubber material; and mounting the at least one uncured rubber material on the carcass so as to form the green form of tread by successive winding of strips.
