Abstract

A roll includes a stationary carrier, a roll jacket, in particular a resilient roll jacket, on the carrier and at least one support element with an associated contact pressure piston, which is supported on the carrier in the region of a pressing zone defined between the roll jacket and a counter surface, while forming a fluid cushion between the support element and the roll jacket. In this arrangement the support element is provided with a pressing section facing the roll jacket, which is bounded in the circumferential direction of the roll by outer edges which are substantially straight and extend parallel to the roll axis, with the width of the pressing section measured between the outer edges being smaller than the maximum outer diameter of the contact pressure piston.
