  • Patent number: 6920730
    Abstract: A multi-layered shingle adapted to be positioned with other similar shingles in an overlapping arrangement on a roof to yield a simulated wooden shake roof covering comprising a headlap portion and a butt portion. The butt portion comprises a series of multi-layered tabs. All the tabs have the same number of layers and each multi-layered tab (a) is separated from the next adjacent multi-layered tab or tabs by a space or spaces, respectively, and (b) comprises an uppermost layer and at least two layers underlying the uppermost layer. Each underlying layer is laminated to the layer above it to form a multi-layered laminated composite. The laminated composite is integral with the headlap portion and the top surface of the uppermost layer of each tab is coplanar with the top surface of the headlap portion. The invention also includes an apparatus and a process for the continuous manufacture of the shingles of the invention.

  • Patent number: 6355132
    Abstract: A method is provided of continuously producing a plurality of laminated shingles, including the steps of advancing a fiber sheet, waterproofing the sheet, applying granules thereto, cutting and separating the sheet into a plurality of strips which are positioned and adhered to each other to be multi-layered, and then cutting the strips while controlling the placement of longitudinal centerlines of the strips, and cutting the multi-layers so as to form a plurality of shingles.

  • Patent number: 6174403
    Abstract: A method for the production of a laminated shingle wherein at least two strips of a continuously advancing sheet are coated with differently colored aggregates of granules. Present among one of the aggregates are a multitude of granules having at least one color and/or hue thereof not present among the granules of the other aggregate or aggregates. The strips are cut from the sheet and laminated one above the other so as to form at least two layers with the differently colored aggregates exposed to view. The difference in coloration creates a pleasing color contrast and accentuates the difference in elevation between the shingle layers.
