GLASS SHEET PRESS BENDING SYSTEM

摘要

Glass sheet bending system includes a furnace through which sheets are sequentially transported in a horizontal position by conveyor. Above the latter is an upper shaping mould having a downwardly facing curved surface, and the sheet is supported against the mould by gas pressure applied below it while a lower mould is moved horizontally into position below the upper mould. The moulds are brought together, and then the upper mould deposits the bent sheet on a transfer mould. Pref. the upper mould is located within the furnace; the lower mould may either within or outside. The lower mould may be in two parts movable with respect to each other.
