Abstract
Complementary roof tiles for a staggered roof tile layout are provided by: (i) extruding and conveying a composite ribbon; (ii) demarcating the composite ribbon into an alternating succession of a first roof tile type and a second roof tile type by engaging the composite ribbon with an upstream cutting blade and a downstream cutting blade, such that each roof tile type is demarcated at an upstream tile edge by one of the cutting blades and at a downstream tile edge by the other of the cutting blades, and such that a selected one of the roof tile types includes a pair of cut-out portions demarcated along one of the upstream and downstream tile edges on opposite ones of the ribbon side edges; (iii) separating the succession of demarcated roof tile types into distinct roof tiles; and (v) curing the distinct roof tiles to form a set of cured roof tiles.
