Abstract

Press for preliminary degassing and lamination of sheet glass by supporting the stack between two shallow heated platens and enclosing the stack between a pair of flexible impermeable sheets. A suction line connection allows the flexible packet contg. the stack to be evacuated. The heated, open-face platens may be lined with a refractory material. The cover can reciprocate between two support tables/lower platens mounted end to end so that one half can be loaded/unloaded while the other half is heated/evacuated. An inflatable jacket is used to seal the boundaries of the chamber. Esp. for mfr. of impact resistant glazing vehicle windscreens, etc. from alternating layers of glass and polyvinylbutyral film, by prepg. degassed stacks prior to loading on autoclave. The flexible sheets adapt to fit stacks of varying plan or thickness. Degassed stacks are prepd. more readily than by use of mechanical clamps in conventional autoclaves.
