ABSTRACT:
A tire repair unit is provided having a plurality of rubberized cord plies which are of a generally circular configuration and are of different area sizes. The several plies are assembled in stacked, superposed relationship but with the plies being of progressively larger area with respect to the smallest area ply designed to be positioned next adjacent the interior surface of a pneumatic tire casing to be repaired. The plies are relatively oriented with a peripheral marginal edge portion of the larger plies projecting a predetermined distance laterally outward with respect to the peripheral edge of the next adjacent ply. A layer of unvulcanized rubber is disposed in overlying relationship to the rubberized cord plies and is disposed next adjacent the smallest area ply. The rubberized cord plies may be unvulcanized or they may be vulcanized as a unit.
