Abstract
ABSTRACT OF THE DISCLOSURE
A device for smoothing a paper or cardboard web, with a smoothing zone passed by the web, and which for achieving a longer web dwell features a certain length, measured in the direction of web travel. Two smoothing surfaces define the smoothing zone on both sides, the one smoothing surface being formed by the shell of a powered roll and the other by a revolving sliding belt. A
sliding shoe which is wrapped by the sliding belt features a sliding surface which is complementary to the shell surface of the roll. A mechanism is provided for mutually compressing the roll and sliding shoe. The sliding shoe, viewed in the direction of web travel, is segmented.
