Abstract
Abstract A tire support stand for holding and fully supporting the bead and sidewall portions of partially toroidally shaped uncured tire bands or green tire carcasses preparatory to loading into shaping and vulcanizing presses or molds is disclosed. The stand comprises a first fixed truncated cone member with its apex downward and a second concentric truncated cone member with its apex opposite or upward, the second member being mounted on a threaded shaft journaled in the base to which the first member is fixed, whereby the second member is adjustable in relation to the first. The first member is adapted to support the tire sidewall region; and the second, the tire bead. The tire stand is compatible with a wide range of tire sizes by virtue of the adjustment feature, and the full circumferential support of both the bead and sidewall portions prevents deformation and resultant adverse effects upon tire quality, performance and safety.
