Abstract

A paper-folding machine with a plurality of folding rollers, which form a folding station in pairs and the distances between whose axes can be set to different folding gap widths corresponding to the paper thickness to be processed and the number of layers of paper passing through the individual folding stations, as well as with mechanical or electronic feed limiters, which are arranged in front of the individual folding stations and can be set individually to different feed lengths. The thickness of the incoming material to be folded, which is determined by means of a thickness-measuring device (40), and the sheet length of the arriving material to be folded, which is determined by a length-measuring device (41), as well as the desired type of folding and/or the set feed lengths of the individual feed limiters (T1-T4), are entered into a process computer (20) to determine the folding gap widths of the individual pairs of folding rollers (W1-W5). The folding gap widths determined are always displayed in digital form and/or sent to a follow-up control device (35), for which they serve as set values for continuously adjusting the individual distances (a) between the axes to these fol…
