Abstract: A method of producing laminated roofing shingles is provided, wherein the shingles are of a dragon's tooth type, and shingles made in accordance with the method, and packages of such shingles.

Abstract: A hip, ridge or rake shingle comprised of a plurality of panels sandwiched on each panel portion side of a layer of shingle material, such that each panel portion can be folded along a fold line, and wherein tabs are provided for each panel portion, adapted to be bent backwardly upon themselves, sandwiching thickening panels therebetween. The shingles can be laid up on a hip, ridge or rake of a roof, to yield desirable thickened features.

Abstract: A hip, ridge or rake shingle is provided, having a high profile, by using various shingle layers to form a built-up wedge-shaped headlap portion, comprised of a plurality of layers of different dimensions in the headlap portion of the shingle, and the process for manufacturing the same from a single sheet of shingle material is provided.

Abstract: The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. One aspect of the invention is a photovoltaic array including a first photovoltaic module and a second photovoltaic module, each comprising a set of linearly arranged features extending from its lateral edge, and an electrical element on its surface, wherein the lateral distance between the electrical element and the center of the linearly-arranged feature closest to the lateral edge is different in the first photovoltaic module than in the second.

Abstract: A method of making a shingle and the shingle made in accordance with such method are provided, in which a shingle-forming layer of shingle material has a plurality of marks applied thereto prior to or after application of decorative granules to its tab region, and wherein the locations of the marks are sensed by a sensor, that then activates and controls the operation and placement of various shingle-completion steps as a function of the placement of the marks.

Abstract: A shingle and a method of and apparatus for making the shingle is provided, whereby patches of preselected granules or combinations of granules are provided, separated by transverse areas of different, preferably darker granules, having slots centrally thereof, to yield the appearance of multi-tab shingles that are thicker than they actually are, with transverse shadow lines. A longitudinal shadow line is optionally provided, along the upper and/or lower portion of the exposed tab.

Abstract: A multi-layer shingle is made by cutting an anterior layer of shingle material to have a headlap area and a tab area, and with a plurality of tabs being present in the tab area, separated by slotted openings. The tab area of the anterior layer has a predetermined design that has a repeatability in the longitudinal direction, or from one edge of a shingle to another in the right-to-left direction, which repeatability is a function of the length of the shingle between said left and right edges, as well as being a function of the number of tabs in the shingle's anterior layer, with the repeatability being smaller or greater than the length of the shingle in the longitudinal direction. Thereby, an ornamental appearance is provided that has a random, natural-looking effect when the shingles are laid up on a roof.

Abstract: This invention is directed to a multi-layer laminated shingle, wherein each shingle layer has granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer. The shingle lends itself to having tabs spaced by voids. Because the tabs in the base layer are inverted, the base layer's butt zone is visible through voids in the tabs of the secondary layer. The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.
