ABSTRACT:
Adjustable drapery traverse rods provided with a motor driven means for moving master carriers utilize a uniformly perforated drive tape and sprocket combination. Because of the perforations in the drive tape, the tape does not form a smooth curve when bent. The drive sprocket is thus adapted to allow the drive tape to lie flush against the sprocket as the tape passes over the sprocket over a wide range of tape tensions and, thereby, to drive the tape smoothly and noiselessly.
