Abstract:
1. A process of continuously producing a plurality of laminated hip, ridge or rake shingles, comprising the steps of: (a) continuously longitudinally advancing an indefinite length of a fibrous sheet of predetermined width, having front and rear surfaces; (b) applying an adhesive to a front surface of the sheet; (c) adhering a plurality of longitudinal strips of granules of at least one predetermined aesthetic to the adhesive that is applied to the front surface of the sheet, to yield a plurality of longitudinal granule bands of said at least one predetermined aesthetic on a shingle sheet of substantially uniformed thickness; (d) applying at least two longitudinal overlay adhesive bands that are transversely spaced apart over a portion of a said at least one longitudinal granule band, to yield at least two overlay bands that are transversely spaced apart and are narrow in a widthwise direction relative to the widths of any of the longitudinal granule bands of clause (c); (e) applying overlay granules to the at least two overlay transversely spaced apart adhesive bands to increase the thickness of the shingle sheet where the overlay granules are applied; (f) longitudinally cutting the shingle sheet into anterior and posterior lengths of shingle sheets of indefinite lengths, so that the overlay granules are on the anterior length of shingle sheet; (g) laminating the posterior length of shingle sheet to the anterior length of shingle sheet to yield a laminated shingle sheet; and (h) longitudinally cutting the laminated shingle sheet into two transversely adjacent components with each component having a longitudinal overlay band and transversely cutting the laminated shingle sheet in the widthwise direction into a plurality of individual lengths of laminated shingles that are any one of (i) individual hip, ridge or rake shingles; and (j) groups of longitudinally connected and partially severed hip, ridge or rake shingles; (k) with said hip, ridge or rake shingles each having a longitudinal overlay band thereon.
