METHOD AND SYSTEM FOR PROCESSING STACKS OF SHEETS INTO BUNDLES OF SECURITIES, IN PARTICULAR BANKNOTE BUNDLES

摘要

There is described a method for processing stacks of sheets (SS) into bundles (5) of securities, in particular banknote bundles, the method comprising the steps of cutting successive stacks of sheets ( SS ), each carrying an array of multiple security prints arranged in a matrix of rows and columns, into successive sets of bundle strips (S ; S* ), and cutting the successive set of bundle strips (S ; S* ) into successive sets (2) of consecutive bundles (5) of securities. This method further comprises the step of counting the number of substrates within each bundle strip (S ; S* ) prior to cutting thereof into the successive sets (2) of consecutive bundles (5). Such counting comprises taking at least one image ( I ) of a at least a portion of a longitudinal side (10) of the bundle strip (S ; S* ) while the bundle strip (S ; S* ) is being displaced along a direction of displacement (A) which is parallel to a direction along which the stacks of sheets ( SS ) are cut into the bundle strips (S ; S* ), and processing the said at least one image ( I ) to derive a substrate count of the substrates within the bundle strip (S ; S* ). Also described in a system for carrying out this method
