A lift device, together with the inverting and stacking mechanism, holds the first sheet of the matched pair stationary above a conveyor while the second sheet is advanced therebeneath to a predetermined position at which point the first sheet is deposited on the second sheet in a closely matched relationship. Hold-down devices maintain the orientation of the first sheet relative to the second sheet.
