Claim:
A method of constructing triple-pane insulating glass units, the method comprising: (a) conveying a first glass pane into a position between two opposed side panels of an assembly apparatus, a first-pane spacer being coupled to one major surface of the first glass pane; (b) securing the first glass pane on an opposite major surface of the first glass pane with the assembly apparatus; (c) rotating at least part of the assembly apparatus 180°, thereby causing the first glass pane to rotate 180°, (d) conveying second and third glass panes into the position between the two opposed side panels of the assembly apparatus, a third-pane spacer being coupled to one major surface of the third glass pane, one edge of the second glass pane being pressed together with one edge of the third glass pane such that the third-pane spacer contacts the second glass pane; (e) pressing one edge of the first glass pane together with the one edge of the second glass pane and the one edge of the third glass pane such that the first-pane spacer contacts the second glass pane; (f) releasing the first glass pane; and (g) conveying the first, second, and third glass panes out of the position between the opposed side panels of the assembly apparatus.
