Abstract

In the case of the method of setting the folding-nip width of a plurality of pairs of folding rollers which are provided on a folding machine, the two folding rollers (12 to 22) of the pairs of folding rollers are brought into contact with one another. A sheet is then guided through between the two folding rollers (12 to 22) of the pairs of folding rollers, as a result of which at least one of the two folding rollers (12 to 22) moves in relation to the other, with a folding nip being formed in the process, it being the case that, for each pair of folding rollers, a measured value corresponding to the folding-nip width is detected as the sheet is guided through. Finally, the folding-nip widths of the individual pairs of folding rollers are set by adjustment of the at least one moveable folding roller (14 to 22) by means of a drive (42), which is connected kinematically thereto, based on the corresponding measured values which have been detected.

Dependent claims

Method of setting a folding-nip width of a plurality of pairs of folding rollers which are provided on a folding machine, each pair of folding rollers including at least one adjustable folding roller, comprising the following steps:

the two folding rollers of said plurality of pairs of folding rollers are brought into contact with one another,
a sheet is passed between said two folding rollers of said plurality of pairs of folding rollers, whereby said at least one adjustable folding roller moves in relation to the other, so that a folding nip is formed, a value corresponding to said folding-nip width being detected for each of said plurality of pairs of folding rollers as said sheet is passed therebetween, and
said folding-nip widths of said each pair of said plurality of pairs of folding rollers is set by adjustment of said at least one adjustable folding roller by means of a drive, which is connected kinematically thereto, based on the corresponding detected value which has been detected for the corresponding pair of folding rollers.
