Abstract
A staple-supporting strip for use with staples when binding documents together which affords removal and retention of the staples. The staple-supporting strip comprises a narrow elongate strip of tough polymeric material between 0.1 and 0.15 mm thick. The strip may be colored or printed with a window identifying the area for reception of the staples. A narrow coating of a low-tack pressure-sensitive adhesive facilitates positioning of the strip on the uppermost sheet of the documents to be stapled together.
Claims11
A staple-supporting strip for use in overlying sheets to be stapled and affording subsequent removal and retention of the staples comprising a narrow elongate strip of tough polymeric material with a thickness of between 0.1 and 0.15 mm (0.004 and 0.006 inch) and having a width dimension of between about 1.5 cm and 2.5 cm (0.5 and 1 inch) and having a length of between 3 cm and 9 cm (1.13 to 3.5 inches), and a band of microsphere structured adhesive means on said strip for temporarily adhering said strip to the surface of a said sheet with no build-up in the adhesive bond, thereby permitting removal of the strip without deleteriously affecting said surface or leaving a residue at any time upon the subsequent removal of the strip.
Method of preparing staples for removal from documents comprising the steps of:
- placing on the sheets to be stapled a narrow elongate strip of tough polymeric material having a width dimension of between about 1.5 cm and 2.5 cm and having a length between about 3 cm and 9 cm,
- pressing the strip against the uppermost sheet to adhere the strip to the sheet by contacting an adhesive coated area of the strip to said uppermost sheet,
- placing the legs of a wire staple across the width of the strip and through said strip and the sheets being stapled,
- whereby upon grasping an end of a said strip the strip can be peeled from said uppermost sheet and the staple will be drawn out of said sheets.
