ABSTRACT:
Apparatus is provided for making a multi-layer shingle 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 shingle 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 anterior shingle layer, with the repeatability being smaller or greater than the length of the shingle in the longitudinal direction. Thereby, the apparatus produces an ornamental appearance that has a random, natural-looking effect when the shingles are laid up on a roof.
