Abstract
A pneumatic tubeless tire is produced in such a way that the tire cord fabric (also known as the tire carcass fabric or ply fabric) has the ends thereof secured during tire building so that separation of the cord fabric ends, and a resulting blemish, does not occur. The carcass fabric is wrapped around a rubber inner lining body with turned up portions of the carcass fabric at a pair of beads on opposite sides of the body, during tire construction. The free ends of the carcass fabric are butted together around the body, to provide a butt seam. The free ends are held together in substantial butting position by placing an open mesh warp knit splicer fabric highly extensible in both the machine and cross-machine directions over the butt seam and affixing the splicer fabric in place using adhesive or the like. Rubber tack may be applied over the splicer fabric. The open mesh fabric appears to have no machine direction or cross-machine direction yarns, but only bias yarns. It typically comprises a two bar partially threaded warp knit mesh fabric whereby the threading is one in, one out, on both the back guide bar and the front guide bar.
