Abstract
A method for manufacturing a tire (1) comprises a step of positioning a reinforcing ply (9) in a rubber material having grooves (6a) such that the reinforcing ply (9) extends through the grooves (6a), 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 (6a).
Claims7
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.
