A curing system including a curing press-post inflator combination wherein the tire moves through the curing and post inflation process under complete control at all times. The post inflator is mounted on the press frame and is aligned with the top mold section of the press in the full open position of the press. The upper or outside bead rim of the post inflator is removed by a mechanism operating, in part, independently of the press top mold section so that the post inflator can be closed and operational prior to the full closing of the press. A chuck in the top mold section not only holds the tire for stripping from the mold sections and bladder but retains control over the tire vertically to place the tire without dropping or any lateral movement on the aligned open bottom or inner bead rim of the post cure inflator.
A tire curing system comprising a press and a separable rim post inflator, said press including a bottom and movable top mold, the latter being movable laterally between said bottom mold and at least one of said separable rims of said post inflator, a stripping chuck in said top mold for holding the tire after stripping from the molds for movement with the movable top mold, and means to lower said chuck while holding the tire when the movable top mold and post inflator rim are vertically aligned to place the tire in the post inflator without any lateral momentum.
A tire curing system for the curing of tires comprising a press and post cure inflator combination in side-by-side relationship, said press including a movable top mold section movable when the press opens to a position above said post cure inflator, a tire chuck in said movable top mold section maintaining the tire centered, and means to lower said chuck to place the tire directly in the post cure inflator without any lateral momentum.
A tire curing press having a top mold section movable laterally fully to open the press, a tire unloading chuck in said top mold section adapted to maintain the tire centered with respect to the top mold section, a post inflator ring vertically aligned with the top mold section when fully open, and means to move the chuck thus centering the tire downwardly when the press is fully open to place the tire on such ring without any lateral momentum of the tire.
A post cure inflator comprising an upper and lower rim, lock means operative to lock said rims together to inflate a tire therebetween and to unlock said rims to permit separation for insertion and removal of the tire therebetween, means vertically to move one of said rims when unlocked and then move said rims relatively horizontally to to offset said rims to clear the lower of said rims for overhead loading of a tire to be inflated, and means alignable with the lower rim operative to load a tire on said lower rim while said rims are held horizontally offset.
