摘要： A roll-up type industrial door (10) includes a flexible vinyl sheet (12) forming a curtain for closing a doorway (14) having an upper end (18), a lower end (20) and two opposite side edges (22). The sheet (12) has a thin main area (26) and elongate side edge sections (28, 30) that are thicker than the main area (26). A sloping shoulder (32) is formed where each side edge (22) section meets the main area (26). A curtain winding mechanism (34, 36, 38) is connected to the upper end (18) of the curtain (12) and is used to raise the curtain (12). A pair of spaced apart guide channels (52, 54) are also provided and the side edge sections (28, 30) are movable therein. Friction reducing, wear resistant fabric strips (90) are bonded to both of the side edge sections (28, 30) and extend therealong. These strips (90) cover the sloping shoulders (88) and are bonded thereto. The strips (90) reduce the amount of friction between the side edge sections (28, 30) and their respective guide channels (52, 54). Preferably the strips (90) are made of one ply polyester monofilament.
