Abstract: A sheet stock having a flexible hinge area is described. The sheet stock includes a substrate having an opening and gap stiffener, and a flexible film covering the opening and defining a flexible hinge area in the region of the opening and gap stiffener covered by the film. Methods for producing sheet stock having a flexible hinge area are also described. The sheet stock may be used in printing, binding, and in other applications.

Abstract: A sheetstock including a base sheet including a cut or perforated shaped area that is separable from the base sheet and a film layer adhered to and confined to a top surface of the shaped area is described. The sheetstock may also include embossments and raised areas or bumps. The film layers may be die cut or cut using a laser. Also described are processes for forming a card form in a sheetstock, and processes for forming offset embossments.

Abstract: A sheetstock includes a sheet, a film layer laminated to the sheet, and an embossment in the sheet surface having a height about the same as a high of the film layer.

Abstract: An album sheet includes a binding edge and an opposite, outside edge. A film is attached to the sheet and extends along at least a portion of the opposite, outside edge. The film can be wrapped around the outside edge so that a portion of the film is on each side of the sheet. The sheet can include a mounting strip and a flexible film strip connecting the mounting strip to the binding edge of the sheet such that there is a gap between the mounting strip and the sheet. The flexible film strip can be wrapped around an outer, spine edge of the mounting strip. A plastic overlay can be attached to one edge of the sheet and dimensioned to cover at least a portion of the sheet.

Abstract: Reinforced paper tabs for use in xerographic reproduction equipment. The tabs include a thin reinforcing film that may optionally be recessed into the thickness of the paper sheet, or may merely be very thin with respect to the thickness of the paper sheet, thus permitting the tabbed sheets to be fed through conventional xerographic reproduction equipment for use in production of booklets and the like. Preferably the reinforcing film includes an outer heat activatable adhesive layer that is melt compatible with xerographic toner, so that xerographic images can be permanently reproduced on the reinforced tabs. The invention also relates to methods of manufacturing and collating such tabbed sheets from web stock.

Abstract: A pad of bound-together individual sheets having a reusable pressure-sensitive adhesive applied to the bound-together edge portion thereof and provided with a removable attachment strip to facilitate the binding of the sheets into a convenient pad for removal and use, and method of making the same.

Abstract: An improved continuous sheet having tear-off perforated edge portions for use with toothed driving wheels (tractor drive transfer mechanism) adapted to mesh with the perforations to advance the continuous sheet in accordance with word processing and printing equipment, said sheet having a recessed, reinforced inner edge portion adjacent to the tear-off line of the perforated edge portion.

Abstract: A paper sheet having a recess along one edge thereof with a non-drying adhesive applied in said recess and a removable protective strip covering said adhesive, the combined thickness of said adhesive and strip being substantially equal to the depth of said recess to provide a sheet of uniform thickness having a protected pressure-sensitive adhesive edge.
