Abstract
An adjusting roller pair, particularly for a rotation folding apparatus in which each roller has an axle, at the ends of which adjusting devices are supported by sleeves to adjust the roller horizontally, vertically and axially. Each roller has a roller body formed of two portions and a non-rotating internal tube. The two portions of the roller body are supported at their ends and horizontally adjustable. The pair of adjusting rollers are employed when non-uniform web tensions transverse to the material web, such as paper, are compensated.
