An indicium for a rubber article having at least one narrow groove therein, the indicium being made of a rubber of a first color such that the narrow groove is perceived as a narrow line of a contrasting color and a method for making same.

Decorative ornamentation for a rubber article and method for making same

A coordinated method and apparatus system for concurrently building an endless band and an endless inextensible belt, transferring the band coaxially of itself to a carcass forming and shaping drum, enfolding beads in inwardly turned ends of such band to form a carcass, then shaping the carcass while swinging the drum about a vertical axis to transfer the endless belt coaxially of itself and of the shaped carcass. The apparatus includes a band building drum with cooperating ply stock servicer for building the tire band and a belt building drum also with a cooperating servicer for supplying belt ply stock and, optionally, tread stock. Axes of the band drum and belt drum are disposed to intersect a vertical axis about which a turret mounted carcass forming drum swings into alternate coaxial alignment with the band building drum and the belt building drum.
