| 摘要 |
The invention relates to a method for the regulation of a web tension in a rotary print machine, whereby the web (B) passes through at least two printing groups (06, 07, 08, 09). A change in the extension of the web during the run, is determined by means of a change in a phase shift between a first phase position of a printing group and a second phase position measured behind a last printing group. The change in phase position is compensated by means of a change in the tension (S) of the web before the first printing group.
