A method and apparatus (200) for building a laminate (10A) and in forming a carcass for a radial ply pneumatic tire (100) from an assembly of tire components is disclosed. The method has the steps of using tire ply material (20), made of elastomeric material (24) reinforced by parallel cords (22) embedded in the elastomeric material (24), as a conveyor strip for itself and other linearally moving tire components, the other tire components being continuously formed and affixed to the ply material (20) to form a laminate (10A) as the ply material moves along the path of conveyance; then, cutting the laminate (10A) into sections of predetermined lengths, each section having a pair of ends (12),(14), the respective cuts being along a cutting path between parallel cords (22) in the ply material; then, splicing the two ends (12),(14) of a cut section to one another to form a tire carcass (10) and then, shaping the tire carcass toroidally. The apparatus includes the ply material (20), a means for conveying the ply material (20), a means for forming a plurality of continuous strips of tire components, and a means for applying the plurality of tire components to the conveying ply (20). The laminate (10A) is preferably wound onto large spools (202) for subsequent use at a tire building station.
