Abstract
A method and apparatus are provided to place a series of timing marks on a granule covered roofing sheet. A rotary pattern cutter cuts a pattern of tabs and cutouts in the continuous granule covered sheet. The rotary position of the pattern cutter and the position of the timing marks are sensed, and the position of the continuous granule covered sheet with respect to the rotary position of the pattern cutter is synchronized in response to the sensed position of the timing marks and the sensed rotary position of the pattern cutter.
