ABSTRACT:
In a banner display device where a plurality of banners are mounted end-to-end upon a carrier web to form a scroll which is wound on a pair of parallel and spaced-apart rollers, means carried on the scroll for stretching or decompressing a medial section of a displayed banner sufficiently to eliminate wrinkles and small distortions. One embodiment uses means for propelling the medial section away from the web comprising resiliently flexible banner end sections or resiliently flexible strips framing the banner which, when partially wound over the rollers, resiliently assume a more planar tangential position in relation to the rollers, thereby allowing the medial section to jut anteriorly away from the carrier.
An embodiment further comprises two independent lateral support members capable of being mounted within enclosures having widely different widths. Components such as motors, transmissions, roller mounting spindles, control sensors and circuitry are mounted directly on the support members.
Command and control of the motors is accomplished through a programmed microprocessor which monitors the status of user manipulable switches and indicators. According to the microprocessor's software/firmware programming, pulse code modulated drive voltages are produced to accurately turn the motors at the proper speeds.
