ABSTRACT:
This invention relates to apparatus for handling glass sheets during shaping and cooling, and in particular to a ring-like member having stop means spaced upstream of an outline supporting surface conforming to and slightly inside the periphery of a bent glass sheet supported thereon to define a position for engaging the trailing edge of the glass sheet while conveying the latter in a downstream direction from a shaping station to a cooling station. The ring-like member has a pair of downstream end portions that are transversely spaced from one another to provide a clearance space to permit the ring-like member to begin to return in an upstream direction to the shaping station before the shaped glass sheet is transferred to a position completely downstream of the ring-like member.
