Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A flexible copy section having particular utility as a component in a rotatable copy display used on a signboard and characterized by having sufficient flexibility to permit it to be simultaneously peeled from the signboard and rolled up for storage and transport and to permit it to be unrolled onto the signboard for display, said copy section comprising: a rectangular, thermally dimensionally stable, flexible sheet of plastic; first and second flexible magnet strips secured to the backside of said sheet, disposed one along and coterminal with each longitudinal edge of said sheet; flexible filler pad means secured to the backside of said sheet in all areas between said magnet strips and having the same uniform thickness as the magnet strips; and a flexible film secured to and coterminal with the front side of said sheet providing weather resistance for and display of indicia.
