Abstract
The present invention relates to a spreader roll. The roll includes a curved central shaft and roll segments arranged in a rotary fashion to this and including a cylindrical shell and at least one radial supporting device oriented against the curved shaft. The roll segments are so arranged that water leaking into the spreader roll will not affect the roll function negatively. The radial supporting device and the curved shaft are hereby assembled together to rotate with one another with the aid of a slide bearing.
