Press roll with a tubular cylinder, featuring on each of its two ends a roll cover with a journal, specifically for use in a roll press consisting of the press roll and a backing roll with controlled deflection, for the treatment of web type material such as a paper web or the like. The inside surface of the tubular cylinder is so shaped across the web width that the shape of the flex line of the tubular cylinder will approximate during operation the flex line of the roll shell of the backing roll. This yields a press roll having a relatively thin-walled tubular cylinder which is lightweight. Nonetheless, an extensively constant line force is achieved in the press gap of the roll press across the web width.
