Abstract
A system for the continuous production of asphalt-based roofing shakes which are tapered and embossed to resemble wood shakes in looks and function; and the shake made thereby. The continuous production system hot-mixes and extrudes the ingredients in a tapered layer on a conveyor belt for embossing and cutting. The system permits wood-shake type variety in size and appearance. The preferred shake includes perlite as a filler and chopped glass fibers as a reinforcer and may be internally colored.
