Abstract
Piles of sheets printed with numbered banknotes are cut into bundles, and the bundles are stacked in magazines of a rotary-drum bundle collector to form packets in which the notes are sequentially numbered, these packets being wrapped and then arranged in a serial ordinator. During delivery to the collector, bundles containing previously marked spoil notes are detected and deviated. The spoil notes are replaced at a substitution station and the bundles remade. Dummy bundles are inserted in gaps left in the delivery line, so as to maintain the correct sequence in the collector, and are removed at the collector output and replaced by the respective remade bundles.
