ABSTRACT:
A display apparatus employing a scrolling principle having two rollers that are activated and supported by independently controllable conveyors. The rollers, which can serve either as a supply roller or as a take-up roller, are attached to opposite sides of a conveyor display platform. The rollers are connected to each other by a traveling full width belt which winds off one roller, is transported via the conveyor display platform, and winds up on the other roller in a scrolling fashion, with carpets of display attached to the belt by a releasable device so as to allow for convenient viewing, examining, storage, and retrieval of the carpets.
