发明名称 Method of making a display folder
摘要 A method of making a display folder is disclosed. The method comprises the steps of providing a sheet of display material having an area to be viewed on one side thereof and then adhering the side of the sheet of display material opposite the viewed side to a base sheet of substantially rigid material. A top sheet of substantially rigid material is then adhered to the viewed side of the sheet of display material by means of an adhesive material, the adhesive material being disposed solely on a portion of the sheet outward of the area to be viewed, thereby sandwiching the sheet of display material between the base and the top sheets to define a panel assembly. The top sheet is then die-cut to form the outline of an aperture, the outline being interior of the adhesive material and outward of the area to be viewed for permitting removal of the portion of the top sheet interior of the outline. Finally, the interior portion of the top sheet is removed to expose the area to be viewed whereby the remaining portion of the top sheet forms a frame around the area to be viewed.
