A chaff collection apparatus (60) includes a chaff tray (62) coupled to the internal drum (20) below the side punches (50). The chaff tray (62) includes a cover (64) comprising a plurality of evenly spaced frangible fingers (66). A specific set of the fingers (66) is removed from the cover (64) according to the locations of the side punches (50) on the internal drum (20). In this manner, only the portions of the cover (64) below the side punches (50) are open to the interior of the chaff tray (62). The chaff produced by each punch (50) passes into the chaff tray (62) through a respective opening (68) in the cover (64), and is captured within the chaff tray (62). The areas of the cover (64) of the chaff tray (62) that are not located below the side punches (50) remain covered by the remaining frangible fingers (66), thereby preventing chaff from escaping the chaff tray (62). <IMAGE> |
