Split ring-like member of adjustable length for shaping glass sheets

Abstract From the Canadian patent

The present invention relates to a ring-like member for use in a glass sheet bending and tempering process most adapted to a process wherein a glass sheet is released from engagement against a vacuum mold of a shape having sharply bent regions about longitudinally spaced transversely, extending lines of relatively sharp bending onto said ring-like member. The vacuum mold has a distance between the sharply bent regions at operating conditions that either equals or is slightly less than the distance desired in the bent glass. In a preferred embodiment the ring-like member, is split into two shaping rails which are separable to adjusted positions wherein the sharply bent regions are spaced to …
