Bending and tempering thin glass sheet - by inertia and gravity bending followed by rapid shuttling to a chilling station

摘要

Flat sheet glass is heated to bending temp. and passed above a ring shaped mould which is rapidly raised to force the sheet to conform to its shape by inertia and gravity. The bent sheet is then shuttled to a location situated laterally of the initial movement of the unbent heated glass, and chilled to temper the glass on the mould. The glass is then returned into alignment with its original path before the mould is lowered and the glass continues on its movement. Sheet glass of =1/8 in. can be bent.
