Patent ID: 7198260

Claim:
Method for automatic synchronization of a number of parallel paper-feeding channels of a paper processing system, such as an inserting system and the like, the method comprising the steps of: a) placing a reference group sequence number that increases from group to group and a reference sheet sequence number that increases within a group from sheet to sheet; b) recording a group sequence number arranged on the corresponding sheet, a sheet sequence number and a statement for marking of a continuing or last sheet of a group being assembled; c) inspecting the sheets ready for release in one of the parallel paper-feeding channels by comparison of the group sequence number and the sheet sequence number with the set reference values; d) releasing the inspected sheets from this channel when the group sequence number and sheet sequence number correspond to the set reference values; e) inspecting additional sheets ready for release in one or more additional parallel paper-feeding channels when the group sequence number or the sheet sequence number of a previously inspected sheet does not agree with the set reference values; f) releasing the sheets from additional parallel paper-feeding channels when the group sequence number and sheet sequence number correspond to the set reference values; and g) marking a group as a defective group and release of the sheet with the smallest group sequence number and the smallest sheet sequence number when none of the inspected sheets has the set reference group sequence number and reference sheet sequence number.
