A staple-supporting strip for use with staples when binding documents together which affords removal and retention of the staples without detrimental affect on the document. The staple-supporting strip comprises two narrow layers of tough flexible polymeric material between about 0.1 and 0.15 mm thick. The strip may be colored or printed with a staple target area and a coating of a pressure-sensitive adhesive holds the bottom layer of the strip on the uppermost sheet of the documents to be stapled together such that the top layer may be peeled from the lower layer to unclench the staple legs during removal.
1. A staple-supporting strip for use in overlaying sheets to be stapled and affording subsequent removal and retention of the staples comprising two narrow elongate layers of tough flexible polymeric material, comprising an upper layer and a lower layer with the layers joined at one end, said upper
1. A staple-supporting strip for use in overlaying sheets to be stapled and affording subsequent removal and retention of the staples comprising two narrow elongate layers of tough flexible polymeric material, comprising an upper layer and a lower layer with the layers joined at one end, said upper layer having a thickness of between about 0.1 and 0.15 mm (0.004 and 0.006 inch) and the lower layer having a thickness between 0.05 mm and 0.15 mm (0.002 and 0.006 inch) and having a width dimension of between about 1.2 cm and 2.5 cm and having a length of between about 5 cm and 7.6 cm (2 and 3 inches), and means on the exposed surface of said lower strip for temporarily adhering said strip to the surface of a sheet and for holding said free end of said lower layer to said sheet when the upper layer is peeled away from said lower layer to remove the staples. 2. A staple-supporting strip as defined in claim 1 wherein said upper layer is longer than the lower layer. 3. A staple-supporting strip according to claim 1 or 2 wherein said strip is formed of polyethylene terephthalate. 4. A staple-supporting strip according to claim 1 wherein said means for adhering and holding comprises a readily releasable pressure-sensitive adhesive. 5. A staple-supporting strip according to claim 4 wherein said adhesive is an acrylate copolymer microsphere structured adhesive. 6. A staple-supporting strip according to claim 4 wherein said adhesive is a narrow strip of double coated pressure-sensitive adhesive tape applied to said exposed surface of said lower layer, with the surface of said tape exposed having a readily releasable pressure-sensitive adhesive coated thereon. 7. A staple-supporting strip according to claim 6 wherein said readily releasable adhesive is an acrylate copolymer microsphere structured adhesive. 8. A staple-supporting strip according to claim 1 wherein one of said upper and lower layers has a coating of transparent colored ink printed on one surface thereof. 9. A staple-supporting strip according to claim 8 wherein said ink is printed on said upper layer to define a rectangular staple-receiving target area on said surface. 10. A staple-supporting strip according to claim 2 wherein said upper layer has means for temporarily adhering the extended end thereof to the surface of a said sheet when said strip is applied to a said sheet and said exposed surface of said lower layer is placed on a said sheet. 11. A staple-supporting strip according to claim 10 wherein said means for adhering said strip and said means for adhering said extended end of said upper layer comprises an acrylate copolymer microsphere structured adhesive. 12. A staple-supporting strip according to claim 10 wherein said upper layer has a coating of transparent colored ink on one surface thereof, said ink coating being applied selectively to define a rectangular staple-receiving target area on said strip. 13. A staple-supporting strip according to claim 1 wherein said strip is formed by folding an elongate strip of said polymeric material transversely. 14. A staple-supporting strip according to claim 2 wherein said strip is formed by folding an elongate strip of said polymeric material transversely with the edges aligned. 15. A staple-supporting strip according to claim 11 wherein said strip is formed by folding a long narrow strip of said polymeric material transversely with the edges aligned.
