ABSTRACT:
Disclosed is a hub replacement device for use in vehicle tire retreading processes. An envelope (30) is sealed against the tire carcass sidewalls (22, 24) to provide an environmental seal of the new tread (54) on the carcass crown (50) during the vulcanization process. Three arcuate rigid plates (16, 18, 20), each with a pair of ribs (56, 58), are installed between the carcass beads (12, 14), for supporting the beads (12, 14), a predetermined distance apart along a majority of the bead circumference. Integral with each support plate (16, 18, 20) are pairs of opposing toggle clamps (32, 40) with hooked ends (36). A pair of annular discs (26, 28) are located on each side of the tire for applying a compressive force on the envelope (30) against the carcass sidewalls (22, 24). The annular discs (26, 28) are each equipped with pairs of anchor loops (42, 44) to which the hooked ends (36) of the toggle clamps (32,40) are releasably engaged.
