ABSTRACT:
An apparatus for controlling the flow of a stream of air consists of an independent module that comprises a support structure on which two rollers are mounted for rotation. A film, having open regions and closed regions, is wound between the two rollers, so that when the rollers are rotated to displace the film between the rollers, the relative positions of the open and closed regions of the film gives selective control of the flow of an air stream directed on to the film. The support structure includes a drive mechanism, for driving the rollers in alternate rotary motion and including a synchronizing shaft for synchronizing the rotary motion of the two rollers.
