ABSTRACT:
An apparatus for randomly and successively selecting and displaying each one out of a stack of banners comprises a wind-in roller around which the entire stack of banners is wound, front face down, with the leading edges of the banners being staggered in an overlapping arrangement on the periphery of the wound stack. A knife bears against the periphery of the stack, compacts and constringes the banners as the wind-in roller is rotated in the direction opposite the winding direction of the stack. The rotation is stopped when the leading edge of the selected banner is near the edge of the knife. The rotation of the wind-in roller is reversed, causing the knife to lift the leading edge of the selected banner and to peel off that banner and all other banners located above it in the stack. A wind-out mechanism places the peeled off banners into a display frame with the inner, front face of the selected one exposed to view. A variation of this device a second knife to separate the selected banner from those located above it so that only the selected banner is displayed. This option allows for back lighting of the selected banner within the display frame.
