  • Patent number: 3947308
    Abstract: Method and apparatus for building a giant tire and particularly for building one or more endless bands of suitable ply stock and for transferring such bands from the band building means to a carcass building drum after which transfer the remaining construction of the tire can be accomplished conventionally. The apparatus includes a wide, flat, endless belt, the surface of which functions as a splicing table whereon successive panels of ply stock are joined edge-to-edge to form a ply and also as means for transferring the so-formed ply directly into wrapping relation with a band building surface whereon such ply is made endless to form a tire ply band. A bridge spanning the width of the belt, at successive selected angles transverse to the direction of movement of the belt, supports at least one ply stock pay-off means from which successive discrete panels of suitable ply stock are disposed on the surface of the belt.
