ABSTRACT:
The process for manufacturing pneumatic tires comprises as essential step the manufacture of a tire body by winding cords or cables (3, 23, 35). The cord or cable is withdrawn from a supply reel (7) under constant tension and laid around and anchored to the bead cores (2; 22; 36; 39) arranged at both sides of the tire. In addition a peripherally extending belt is applied which again can be formed by winding cords or cables, and the tire is completed by injection molding or die casting elastomeric material. An apparatus suitable for performing said process comprises in addition to an interior mold (1, 21, 38) two sets of outer molds, the first set allowing the shaping of an inner tire layer provided with protrusions serving as spacers for the winding of cables or cords and the second set corresponding to the external shape of the tire (FIG. 2).
