A roll-up strip curtain barrier apparatus is provided which provides a curtain member suspended from a support roller rotatably mounted about a door opening. The curtain member has a plurality of flexible curtain-like strip panels which are adapted to span the door opening and provide an air-blocking seal. In one embodiment, the plurality of rows, each row having a plurality of adjacent strip panels. In one mode of operation, the flexible strip panels deflect in response to personnel and material passing through the door opening. In another mode of operation, the support roller may be rotated so as to wind and elevate the curtain member about the roller and create an unobstructed door opening.

L'invention concerne un dispositif enroulable (10) composé de bandes, constituant une barrière et comportant un rideau (20) suspendu à un rouleau de support (22) monté rotatif au-dessus de l'ouverture (12) d'une porte. Le rideau (20) possède une pluralité de panneaux souples sous forme de bandes (34) conçus pour s'étendre à travers l'ouverture de la porte et bloquer la circulation de l'air. Dans un mode de réalisation, la pluralité de panneaux (34) est disposée en une pluralité de rangées (40, 42) possédant chacune une pluralité de panneaux (34) contigus. Selon un mode de fonctionnement, les panneaux souples (34) sont déviés sous l'effet du passage de personnel et de matériel à travers l'ouverture de la porte (12). Selon un autre mode de fonctionnement, on peut faire tourner le rouleau de support (22), afin d'enrouler et d'élever le rideau (20) autour du rouleau (22), de manière à dégager l'ouverture (12) de la porte.
