ABSTRACT:
A flexible binding blank is die-cut from a sheet of polyethylene terephthalate to form a tape with bands projecting at right angles from one edge. In one embodiment, the tape has a perforated longitudinal center line with rectangular apertures opposite each band, and a coating of pressure sensitive adhesive. The bands are threaded through apertures in a stack of pages, and folded back so that free ends of the bands project through the rectangular apertures. In one embodiment, the tape is folded along its perforated center line securing the bands into rings, and projecting free ends cut off. In another embodiment, the bands are notched to engage notches in the tape.
