Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A device for applying a reinforcing tab to a sheet in a loose-leaf binder at a region of the sheet between a hole in the sheet through which a ring of the loose-leaf binder passes and an adjacent edge of the sheet, comprising a holder for holding a supply of reinforcing tabs carried on a carrier strip, an elongated member projecting from the holder, the member being sized to fit within the ring of the loose-leaf binder and to position the carrier strip between the edge of the sheet and the hole in the sheet through which the ring passes, a deflecting edge adjacent to one end of the projecting member around which the carrier strip is adapted to be passed to separate a tab therefrom, and applicator means adjacent to the deflecting edge for pressing the separated tab onto the sheet.
Claim 2
Independent Claim
142 words
A device for applying a reinforcing tab to a sheet in a loose-leaf binder at a region of the sheet between a hole in the sheet through which a ring of the loose-leaf binder passes and an adjacent edge of the sheet, comprising a holder for holding a supply of reinforcing tabs carried on a carrier strip, an elongated member projecting from the holder, the member being sized to fit within the ring of the loose-leaf binder and to position the carrier strip between the edge of the sheet and the hole in the sheet through which the ring passes, a deflecting edge adjacent to one end of the projecting member around which the carrier strip is adapted to be passed to separate a tab therefrom, and applicator means adjacent to the deflecting edge for pressing the separated tab onto the sheet.
