ABSTRACT:
A device for displaying a scrollable banner wherein the single banner pick-up roller used in prior art devices is replaced by a multi-roller spool. Each multi-roller spool comprises at least two rollers connected with spool belts which define a winding area much longer than that of any single roller. The spools are rotatably mounted within a display housing. Motors drive the multi-roller spools. Additional features include: convex style crowned pulleys for automatically centering each of the spool belts, a centrally located roller separator mechanism which gives a convex crown structure to the entire spool itself whereby the banner is automatically centered, and a display housing of far reduced depth.
