Abstract: Banknotes are sorted into a first group fit for reuse, and a second group unfit for reuse, the notes being fed to a fit not collecting device (5D) and an unfit note collecting device (5E). The unfit note collecting device (5E) includes a "half-wrapping" device (6D) for "half-wrapping" or banding the unfit notes and a destroying unit (8) for preventing the unfit from being reused. The unfit notes are delivered selectively to the banding device (6D) or the destroying unit (8). Counterfeit and reject notes are diverted prior to sorting to cassette bins with a classification card and the band around the original banknote bundle. The fit notes are sorted into 'different', 'fine' and 'correct' notes prior to banding and wrapping. Prior to sorting, the band around the banknote bundle is removed by bending the bundle downwardly so that the band separates from the surface of the bundle and is engaged by grippers. The bundle is then bent upwardly so that the band on the other side of the bundle separates from the bundle and is cut. Conveyor belts then remove the banknotes leaving the cut band in the grippers, (Figures 8-15). <IMAGE>
