Abstract
In a method and an apparatus to test folded sheets for folding deviations from the reference folding line, to be used in pocket folding - or cutting folding machines, markings are made on the folding material, corresponding with the print format, and are sensed by sensors, preferably electro-optical reflection sensors after the material has been folded inside the machine, to obtain the position information. The evaluation position information derived from the output of the sensors for a number of folded sheets is rigid to determine the adjustments of the machine necessary to correct the deviations.
