A vacuum mold for supporting a flexible sheet of interlayer material for assembly against a bent glass sheet or between a pair of bent glass sheets of matching configuration has a first apertured wall shaped to conform to the shape of the bent glass, and a second apertured wall of conforming shape adapted for coupling to a vacuum source to form and hold the flexible sheet of interlayer material against the mold in unwrinkled condition. The mold is pivoted to a carriage from a mold loading orientation of convex elevational configuration to a mold unloading orientation of concave elevational configuration.

Vacuum mold for making a windshield subassembly

Assembly apparatus including a vacuum mold for supporting a flexible sheet of interlayer material for assembly against a bent glass sheet or between a pair of bent glass sheets of matching configuration has a first apertured wall shaped to conform to the shape of the bent glass, and a second apertured wall of conforming shape adapted for coupling to a vacuum source to form and hold the flexible sheet of interlayer material against the mold in unwrinkled condition. The mold is pivoted to a carriage from a mold loading orientation of convex elevational configuration to a mold unloading orientation of concave elevational configuration. Carriage movement between a mold loading station and an assembly station is correlated to the elevational configuration of the mold in assembling said flexible sheet of interlayer material against one or more bent glass sheets.

A mold for supporting a flexible sheet of interlayer material for assembly against a bent glass sheet or between a pair of bent glass sheets of matching configuration has a first apertured wall shaped to conform to the shape of the bent glass, and a second apertured wall of conforming shape adapted for coupling to a vacuum source to form and hold the flexible sheet of interlayer material against the mold in unwrinkled condition. The mold is pivoted to a carriage from a mold loading orientation of convex elevational configuration to a mold unloading orientation of concave elevational configuration. Carriage movement between a mold loading station and an assembly station is correlated to the elevational configuration of the mold in a method of using the mold in assembling said flexible sheet of interlayer material againt one or more bent glass sheets.
