Abstract
A high speed parallel manufacturing line for manufacturing insulated glass units, the manufacturing line including a gas filling topping press that mates a spacer applied lite supplied to the topping press and a topping lite supplied to the topping press to create an insulated glass unit and fills the insulated glass unit with a non-air gas. A heating station applies localized heat to adhesive of the spacer material. A sealing press applies pressure to the insulated glass unit and facilitates further sealing of the spacer material to the spacer applied lite and the topping lite. The line may include a fourth corner sealer that completes sealing of the airspace of the IGU prior to finishing of the IGU.
Claims10
A method of manufacturing insulated glass units, comprising:
- applying a single seal spacer material to a spacer applied lite continuously proximate a perimeter of the spacer applied lite while leaving an opening in the single seal spacer material;
- conveying the spacer applied lite to a press and seal mechanism;
- mating a topping lite with the spacer applied lite with the press and seal mechanism to create an insulated glass unit with the opening in the single seal spacer material remaining open;
- filling the insulated glass unit with a non-air gas through the opening in the single seal spacer material;
- closing the opening without application of further sealant thereby making the insulated glass unit gas tight;
- applying pressure to the insulated glass unit to further seal the insulated glass unit in a separate second press following the press and seal mechanism;
- and
- conveying the insulated glass unit to an outfeed queue station without applying further sealant.
