| 摘要 |
The invention relates to a method for controlling a circumferential register in a web-fed rotary press, according to which an actual value pertaining to a tension (51-55) of a web (03) passing through the printing units (04, 06, 07, 08) is determined, and an angular position and/or an angular velocity of a cylinder (12, 16) of a first printing unit (04) with regard to a cylinder of a second printing unit (06) is changed according to this determined tension. The correction of a register offset ensues without controlling the tension (51-55) and without the use of an optical recognition system by determining the value of the necessary change for the angular position (deltaphi) and/or the angular velocity (deltaphi) as a function of the measured tension (51-55) of the web (03). |
