Abstract
A method monitors the length of sheets, such as banknotes, passing a predetermined position. The length of a sheet is monitored at two laterally spaced locations, and the difference between the monitored lengths is compared. If the difference is small, this indicates that both monitored lengths are an accurate indication of the length of the sheet. An average of the two monitored lengths is determined and compared with at least one predetermined reference value to determine the acceptability of the sheet. If the average falls within a predetermined range, the sheet is acceptable.
