Abstract
The roller is provided for pressure treatment of a strip of paper, textile, plastic film, sheet metal or similar material. It includes a hollow roller made of a fiber-reinforced synthetic resin material, and a cross-beam which passes through the hollow roller lengthwise. The cross-beam is mounted at its ends, in external supports, so as not to rotate. Hydrostatic support elements are arranged on the cross-beam on the side on which pressure is exerted. The elements can be pressed against the inside circumference of the hollow roller by means of a hydraulic fluid. The support elements have a length not exceeding 20 cm in the longitudinal direction of the hollow roller, follow each other closely in the longitudinal direction of the cross-beam, and can all be controlled independently of one another.
