US 4,677,910 A · Process for processing security paper webs or security paper sheets to form bundles of security papers

Abstract

Processing is based on print carriers in the form of security paper webs or security paper sheets, containing security paper prints which are arranged in the manner of matrices in transverse rows and longitudinal rows and on which spoilt notes are identified by a mark which can be read by a reading instrument. The print carriers pass, in succession, by a reading instrument which detects the positions of the spoilt notes and feeds them into a computer for storage, a cancellation printer controlled by this computer, which provides spoilt notes with a cancellation print, and a numbering machine. The numbering mechanisms of this numbering machine are moved forward by the computer in such a way that always the satisfactory security paper prints, placed in succession in any longitudinal row, are serially numbered, the spoilt notes being neglected. Subsequently, the print carriers, having passed by another reading instrument, are cut up into individual security papers, the spoilt notes are separated out in a separation device and the remaining, serially numbered individual security papers are assembled to form bundles, each having a complete numerical sequence. In this way, correct and complete numerical sequence of the security papers contained in the automatically produced security paper bundles and security paper parcels is ensured, in spite of the separation of spoilt notes.

Dependent claims

Process for processing print carriers, printed with security paper prints, in the form of security paper webs or security paper sheets, the security paper prints of which are arranged in the manner of matrices in transverse rows and longitudinal rows, comprising the steps of

a. marking spoilt prints detected on said print carriers;
b. scanning the positions of all spoilt prints on the printed carriers and storing these positions before the print carriers are numbered;
c. feeding said print carriers in a numbering machine, where only the satisfactory security paper prints are serially numbered on the print carriers, while said serial numbering is interrupted when a spoilt print appears, and continued when the next satisfactory security paper print appears, the numbering mechanism of said numbering machine being controlled individually as a function of said stored positions;
d. applying cancellation prints to said spoilt prints, said operation being controlled as a function of said stored positions and being effected before cutting up said print carriers;
e. cutting up said print carriers to individual security papers cut to size;
f. eliminating the individual security papers having spoilt prints;
g. assembling the remaining serially numbered individual security papers to form bundles with complete numerical sequence in each case.

a. numbering machine;
b. at least on reading instrument for reading the marked spoilt prints, said reading instrument being situated in the direction of transport of the print carriers in front of said numbering machine and designed for ascertaining the positions of the spoilt prints;
c. a computer in which the positions of spoilt prints ascertained by said reading instrument can be stored and by which said numbering machine is controlled in such a way that only satisfactory security paper prints are serially numbered, the spoilt prints being excluded;
d. cutting machines for cutting up the print carriers to individual security papers;
e. a cancellation printer for the spoilt prints, controlled by said computer, installed in front of the cutting machines;
f. a separation device mounted behind the cutting machines and being controlled by the computer or an additional reading instrument and designed for separating out from the transport sequence the individual security papers which have been marked as spoilt notes;
and
g. a station for forming and packaging security paper parcels.
