System information


The self-regulating compensating roller ensures a symmetric web tension distribution over the total web width. This eliminates uneven web tensions, caused by length differences between the left and right web edge.

Area of use

The compensating roller is used in corrugated cardboard systems, in order to implement a symmetrical distribution of the web tension. Typically, the compensating rollers are used in the single facer machine and after the preheating group.


The wrapping around the compensating roller should be between 30 and 90°. The actuation direction must be at the angle bisector. The function is given in both directions of web travel.
