  • Method for cementing in the manufacture of double-pane insulating glass units
    Patent number: 3974011
    Abstract: Manufacture of double or plural pane insulating packages by placing panes together with a spacer, thereby leaving an interspace at the periphery into which cement is injected. Two nozzles are used to inject cement into the interspace, starting from a common starting region and working in opposite directions around the periphery to a common terminal point. Conveyors and control systems are provided to mechanize the process.
