ABSTRACT:
A closed torus tire in which the cord or wire reinforcement ply, or plies, surround the inflation chamber which can retain pressure without being mounted on a wheel. The reinforcement ply is continuous circumferentially of the tire and axially in the crown and sidewalls. The circumferential ply edges are lap-spliced in the inner wheel-engaging part, rather than being folded around bead cores. The tire is made without use of a building core of any kind, thus avoiding the cost and difficulty of removing such core from the completed tire. The tire is made by wrapping the reinforcement ply, or plies, about a cylindrical drum to form a sleeve. An inner liner is then wrapped about the sleeve, a reversal of normal tire building practice. One circumfferential edge of the sleeve is then moved outward and axially over the remaining sleeve, beyond the other, unmoved edge. The one edge is then moved inward and axially under the other edge to form the lapped splice.
