Abstract: A method of making a belted, radial ply tire in a single stage is disclosed wherein a body layer is formed from one or more body plies of cord fabric which are wound around a tire building drum in such a manner that the cords extend parallel to the axis of the building drum. At least a pair of breaker plies of cord fabric are wrapped around the body plies to create a breaker layer with the cords in each breaker ply being oppositely disposed in adjacent plies, extending parallel to one another within each breaker ply and forming a bias angle of from about 50.degree. to about 70.degree. with a circumferential line corresponding to the crown centerline of the completed tire. A strip of high soft stretch reinforcing tape is wrapped helically over the breaker layer at an angle of substantially 90.degree. to a plane including the axis of the body layer to form a 0.degree. cap band preparatory to securing a tread slab over the breaker layer, completing the raw carcass.

Abstract: The single-stage building of 0.degree. belted pneumatic tires completely in flat band form on standard building drums, is disclosed. The feasibility of the process rests on the provision of the substantially inextensible metallic or non-metallic belt cords in the form of longitudinally extensible high "soft stretch" tapes. In a preferred version of the invention, the tape is composed of a plurality of cords each having formed therein a multiplicity of undulations which in any given straight length of the tape are substantially planar, the cords being disposed in side by side relation so that the planes of the undulations of each cord are generally parallel to the planes of the undulations of each adjacent cord, and the cords together with a relatively weak and frangible but only minimally undulated stabilizing yarn for the tape being secured to each other and held in their undulating state by a relative weak, chain stitch knitted, frangible stitching yarn or thread.
