Abstract (en)
[origin: EP0271666A2] In the method for monitoring printed sheets in a collator, the thickness of the printed sheets is measured in the individual feeders (1) and, in the event of deviation from a fixed tolerance range, a missing or faulty printed sheet is detected and a control pulse triggered for stopping the collator or for removing the faulty book block. So that the correct reference value is found automatically for each feeder, it is provided for each individual feeder (1) that, as soon as a specified number (n) of successive measurements of essentially the same measured values is determined, the position of the tolerance range is determined with the last of these measured values. <IMAGE>
