Abstract: A low-cost disposable tab applicator and method of applying reinforcing tabs to the margin area of a sheet in a loose-leaf binder between a hole in the sheet through which a binder ring passes and an adjacent edge of the sheet, without the necessity of removing the sheet from the binder.

Abstract: A method and apparatus for automatically applying reinforcing tabs to sheets in a loose-leaf binder includes a projecting tab guide sized to fit within a ring of the loose-leaf binder and adapted to apply a reinforcing tab between the edge of the sheet and a hole in the sheet through which the ring passes. Pressure-sensitive adhesive-back reinforcing tabs are separated from the carrier strip as the strip passes around a deflecting edge adjacent to an end of the tab guide. An inclined pressure foot presses the separated tab onto the sheet to attach it thereto.
