A method and apparatus for manufacturing a flexible curtain (128). Edges of a
polymeric material are folded back on themselves by using beveled rollers (110-
116). A portion of the folded edges (132) are secured and a portion is left
unsecured or free. The free, or unsecured flap (135) of the folded edges (132)
absorbs shock associated with storm disturbances. Edge rollers (118, 119) are
used to laminate the folded edges (132) of the flexible curtain(128)
selectively such that only a portion of the folded edge (132) is secured
leaving the flap (135) unsecured. Stitching (120, 121), ultrasonic welding
(405, 406) and gluing (170) are alternative ways and/or additional ways of
providing for the securement of a portion of the edge to itself. Perforations
are made by perforating rollers (122, 123), stationary punch (1000) or
indexing punch (1200) in the secured portion of the folded edge.
Procédé et appareil pour fabriquer un rideau souple (128). Des bords en matériau polymère sont repliés en arrière au moyen de rouleaux biseautés (110-116). Une partie des bords repliés (132) est fixée, et une autre partie est laissée libre. Le rabat libre non fixé (135) des bords repliés (132) absorbe les chocs liés aux perturbations que provoque la tempête. Des rouleaux d'extrémité (118, 119) servent à laminer les bords repliés (132) du rideau souple (128) de manière sélective, de façon que seule une partie du bord replié (132) soit fixée en laissant le rabat (135) non fixé. On peut utiliser de façon alternative ou complémentaire la couture (120, 121), le soudage par ultrasons (405, 406) et le collage (170) ainsi que d'autres procédés pour fixer une partie du bord au bord proprement dit. On fait des perforations en perforant les rouleaux (122, 123), par l'application d'un poinçon stationnaire (1000) ou d'un poinçon d'indexation (1200) dans la partie fixée du bord replié.
