Abstract
A shingle and a method of and apparatus for making the shingle is provided, whereby patches of pre-selected 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.
Claims14
A multiple layer shingle having an anterior shingle layer and a posterior shingle layer, with the anterior shingle layer being of predetermined thickness between upper and lower surfaces thereof;
- comprising a web of reinforcing material coated with a solidified coating material, with the shingle having a butt portion adapted to be substantially covered by another shingle when installed on a roof, and a tab portion adapted to be substantially exposed when installed on a roof;
- each of which portions extend longitudinally of the shingle;
- with the butt portion having a lower end and an upper end and with the tab portion having a lower end and an upper end;
- and with the lower end of the butt portion merging with the upper end of the tab portion;
- with a layer of granules adhered to the coating material on the butt portion of the shingle;
- with a plurality of longitudinally spaced-apart first areas of granules adhered to the coating material on the tab portion of the shingle, leaving transverse longitudinally spaced-apart second areas between adjacent ones of said first areas;
- said transverse second areas having granules adhered to the coating material thereon;
- with the granules in said transverse second areas being of a visually distinct shading that is visually different than the shading of granules in said first areas;
- with transverse slots extending into said second areas from said lower edge thereof, toward said butt portion, separating said longitudinal tab portion into a plurality of tabs spaced apart by slots, with each slot being narrower in the longitudinal direction than the said transverse second area in which it is located;
- and with visually distinct granules of said second areas being longitudinally spaced apart on each side of each said slot, with each layer other than the anterior shingle layer comprising a web of reinforcing material coated with a solidified coating material with granules carried thereby, and with an adhesive securing the layers of the laminated shingle together.
A shingle of predetermined thickness between upper and lower surfaces thereof;
- comprising a web of reinforcing material coated with a solidified coating material. with the shingle having a butt portion adapted to be substantially covered by another shingle when installed on a roof, and a tab portion adapted to be substantially exposed when installed on a roof;
- each of which portions extend longitudinally of the shingle;
- with the butt portion having a lower end and an upper end and with the tab portion having a lower end and an upper end;
- and with the lower end of the butt portion merging with the upper end of the tab portion, with a layer of granules adhered to the coating material on the butt portion of the shingle;
- with a plurality of longitudinally spaced-apart first areas of granules adhered to the coating material on the tab portion of the shingle leaving transverse longitudinally spaced-apart second areas between adjacent ones of said first areas;
- said transverse second areas having granules adhered to the coating material thereon;
- with the granules in said transverse second areas being of a visually distinct shading that is visually different than the shading of granules in said first areas;
- with transverse slots extending into said second areas from said lower edge thereof, toward said butt portion, separating said longitudinal tab portion into a plurality of tabs spaced apart by slots with each slot being narrower in the longitudinal direction than the said transverse second area in which it is located;
- and with visually distinct granules of said second areas being longitudinally spaced apart on each side of each said slot, including a sensible mark carried by the shingle.
