Abstract
A method for checking and combining separate documents having sections of text imprinted thereon for ensuring that documents taken from two or more groups possess the same identical sections of text includes the steps of conveying the documents taken from the groups of documents along a conveyor to a scanning position in front of an opto-electrical scanning device and scanning the documents with the opto-electrical scanning device in order to produce a series of digital signals. The digital signals associated with documents from two different groups of documents are then compared in a comparator to determine if the signals are identical.
