Abstract: A method and apparatus for manufacturing a flexible curtain as disclosed and claimed. Edges of a polymeric material are folded back on themselves. A portion of the edges are secured and a portion is left unsecured or free. The flexible curtain is used in a windlocking apparatus to prevent the unwanted intrusion of wind, water and debris into a building opening. The free, or unsecured flap of the folded edge absorbs shock associated with storm disturbances. Edge rollers are used to laminate the edges of the curtains selectively such that only a portion of the edge is secured leaving the flap unsecured. Stitching, ultrasonic welding and gluing are alternative ways and/or additional ways of providing for the securement of a portion of the edge to itself. Perforations are made in the secured portion of the folded edge.
