Bladder holder assembly for tire making machine

摘要

The device comprises five concentric rings, the outer surfaces of which are contoured to form four circumferential split grooves in which the beads of the two bladders are clamped. The rings are assembled in proper angular position on dowels fixed to one end ring and extending through the three adjoining rings. Certain of the inner rings are clamped together as sub-assemblies by screws through their rims, and all five are clamped together by other screws extending through their rims.
