Abstract: A plurality of asphalt shingles, customarily having dimensions one by three feet and cut-outs spaced a foot apart, are stacked in an inverse cupped disposition. The stack so-cupped is placed on a shingle feed device disposed over an endless belt-like member which has parallel spacing bars disposed perpendicular to the direction of travel of the endless member and which are spaced apart five inches from leading edge to leading edge. Each spacing bar slices off the lower of the cupped shingles held in the feed device which are carried therefrom by the endless member, a single shingle being carried by each spacing bar whereby each shingle is overlapped by the following shingle the same amount as would occur on a roof except that the shingles are inverted and, at this point, not staggered laterally. Under the overlapped shingles, a pair of diverging chains have stagger plates extending outwardly therefrom, the chains moving at about the same speed as the endless member so that the stagger plates each engage one of the cut-out portions of each shingle and cause the shingles to move alternately outwardly so as to be staggered laterally as they would be on a roof. Resiliently biased fingers engage the shingles on the moving member to ensure alignment with the spacing bars and a series of rollers on each side bear against the edges of the shingles finely to adjust their lateral position. Hot, quick acting glue is then applied from above the endless member to the exposed shingles in a predetermined pattern and extensible Kraft paper which is two feed in width is applied from an overhead roll under a compression belt to the center of the array of shingles whereby the shingle array is glued by intermittently applied beads of glue to the Kraft paper on a continuous basis. The Kraft paper is thereafter cut so as to connect only a predetermined number of shingles-say twenty-into a single array which are moved off the end of the endless belt by gravity and down a slide into a container. As the array is received in the container, the paper automatically folds between the individual shingles in an accordion-like manner. The container is inverted and secured, and the array, when opened, may be easily extended on the roof deck to its desired position. In a modification, the desired stagger plates can be on a converging chain under the endless member and brought to bear against the edges of the shingles rather than the cut-outs. In any event, the cut-outs can be a slit rather than spaced slots and the shingles need not be of the asphalt type.
