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.

In the manufacture of double-pane glass insulating units comprising first and second panes separated by a frame-shaped spacer and formed into a pane package by the injection of a cement into an interspace along the periphery of the pane package, which interspace is limited by the outside of the spacer and edges of the two panes projecting beyond the spacer, the improved apparatus for injecting the cement comprising: A. a conveyor means for carrying the pane package, B. pressure roller means for holding the pane package on the conveyor, C. two nozzle means for injecting cement into the interspace, D. control means responsive to the presence of the two nozzle means at a common starting region for causing the two nozzles to begin injecting cement into the interspace at said common starting region on the periphery, responsive to the continued proximity of the two nozzles to the interspace to cause the nozzles to continue to inject the cement into the interspace while causing the two nozzles to move in opposite directions along the periphery, and responsive to the presence of the two nozzle means at a common terminal region for causing the nozzles to cease to inject cement into the interspace as the two nozzles reach a common terminal region, and E. means for rotating the nozzles to cause them, while injecting cement, to continue to maintain a constant angular relationship with the periphery of the pane package.
