ABSTRACT:
A transport roller unit, which has a plurality of rollers arranged next to one another on a bearing shaft, rests against the transport rollers of a transport roller pair. The rollers are mounted independently rotatably on bearing bushings that are joined positively to the bearing shaft. The rollers are associated with a first and a second roller group, of which the first roller group is mounted, offset by an amount (x), eccentrically with respect to the longitudinal axis of the pressure roller unit. The second roller group is mounted offset, by the same amount (x) in the opposite direction to the rollers of the first roller group, eccentrically with respect to the longitudinal axis of the pressure roller unit. The rollers are arranged in such a way that of each two rollers arranged next to one another, one is associated with the first roller group and one with the second roller group. The rollers of the first roller group rest nonpositively against the one transport roller, and the rollers of the second roller group rest against the other transport roller.
