摘要： A method of manufacturing roofing felts, cap sheets, base sheets and similar built-up roofing products from fibrous mats includes: supplying a roofing mat to a manufacturing process; moisturizing the roofing mat by applying steam or a liquid mist to one or both major surfaces of the roofing mat during the manufacturing process to increase the moisture content of the roofing mat and reduce the amount of hot bitumen accepted by the roofing mat during a coating operation; and applying a hot bitumen coating to one or both major surfaces of the roofing mat during the manufacturing process after the moisture content of the roofing mat has been increased by the moisturizing step.
