DRAINAGE MEMBERS FOR FLAT ROOFS AND METHODS OF MAKING SAME |
摘要 |
Processes of making slightly sloped roofing members/products (30, 130) for drainage of essentially flat roofs and the products (e.g., sloped roofing members) produced thereby are provided. Some of the processes comprise feeding a series of mold members (50, 150) in a conveyance direction (26) toward a laminator (22) wherein the sloped roofing members are cured. In various embodiments such processes comprise feeding a bottom facer (42) in the conveyance direction toward the laminator (22); depositing a foam-forming mixture (46) on the bottom facer (42); feeding a top facer (44) in the conveyance direction toward the laminator whereby the foam-forming mixture is interposed between the bottom facer (42) and the top facer (44); feeding the series of mold members (50, 150) in the conveyance direction toward the laminator (22) and beneath the bottom facer (44); and curing the foam-forming mixture in the laminator to form a solidified web comprising the sloped roofing member (28, 128). Each of the mold members (50, 150) is configured to impart at least one non--orthogonally sloped surface to a corresponding sloped roofing member. |
