Following finishing, asphalt felt to be used in roll goods is wound on a mandrel,
cut to the proper length, and packaged. When shingles are being made, the material from the
finish looper is fed into the shingle cutting machine. After the shingles have been cut, they are
moved by roller conveyor to manual or automatic packaging equipment. They are then stacked
on pallets and transferred by fork lift to storage areas or waiting trucks (U.S. EPA, 1980).
