ABSTRACT:
A method for manufacturing a tire carcass includes the step of providing a liner of an air-impermeable material. A carcass ply material is prepared by heating and stretching plastic cords and embedding the stretched plastic cords in rubber. A ply of the carcass ply material is placed onto the liner with overlapping leading and trailing ply ends. The overlapping ply ends are heated for returning the stretched plastic cords into an unstretched state. Bead cores are then positioned onto the ply. The lateral edges of the ply are folded over the bead cores. The folded lateral edges and the bead cores are then enveloped by lateral strips.
