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.
Claims20
An installation for processing piles each formed of a constant number of sheets each printed with N numbered security papers such as banknotes, in which the numbering of the security papers at like positions of the successive sheets of each pile and of the successive piles is in an uninterrupted sequence, and on which sheets some of the security papers may bear control marks recording imperfections, into bundles of security papers each having said constant number of security papers in sequential order and arranged in packets of sequentially numbered bundles, in which said imperfect security papers are replaced by perfect ones, comprising:
- means for receiving a pile of sheets and cutting the pile into N bundles of security papers;
- means for conveying the bundles of each successively cut pile in a given order along a first path;
- a detector for detecting the presence in a bundle along said first path of at least one marked imperfect security paper;
- means responsive to said detector for deviating from said first path said bundles including imperfect security papers;
- means for placing dummy bundles each in the place in said first path formerly occupied by a deviated bundle;
- a bundle collecting device including N individual magazines for receiving respective ones of the N bundles formed from each pile of sheets, and the respective replaced dummy bundles, at the end of said first path to form N packets of a given number of bundles from a given number of piles;
- means for conveying the packets of bundles from said collecting device along a second path to a packet wrapping device;
- a substitution station for receiving said deviated bundles and treating them to remove imperfect security papers and replace them by perfect numbered security papers, and reform the bundles in the correct order;
- and at least one bundle replacement station located before said packet wrapping device where said dummy bundles are removed from the at least partly formed packets and replaced by the respective reformed bundles delivered by said substitution station.
A method of processing piles each formed of a constant number of sheets each printed with N numbered security papers such as banknotes, in which the numbering of the security papers at like positions of the successive sheets of each pile and of the successive piles is in an uninterrupted sequence, and on which sheets some of the security papers may bear control marks recording imperfections, into bundles of security papers each having said constant number of security papers in sequential order and arranged in packets of sequentially numbered bundles in which said imperfect security papers are replaced by perfect ones, comprising:
- cutting each pile into N bundles of security papers;
- conveying the bundles of each successively cut pile in given order along a first path;
- detecting the presence in a bundle along said first path of at least one marked imperfect security paper;
- deviating from said first path said bundles including imperfect security papers;
- placing dummy bundles each in the place in said first path formerly occupied by a deviated bundle;
- individually collecting respective ones of the N bundles formed from each pile of sheets, and the respective replaced dummy bundles, at the end of said first path to form N packets of a given number of bundles from a given number of piles;
- conveying the packets of bundles along a second path and wrapping the packets;
- treating said deviated bundles to remove imperfect security papers and replace them by perfect numbered security papers, and reform the bundles in the correct order;
- and, before wrapping the packets, removing said dummy bundles from the at least partly formed packets and replacing them by the respective reformed bundles.
