Abstract
A controlled-deflection roll having a stationary roll support or carrier and a tubular roll shell rotatable about the stationary roll support. The tubular roll shell bears upon the roll support or carrier through the intermediary of at least one bearing or support element. The roll shell is provided at its ends with guide members which are rotatably mounted in the roll shell and which are guided on the roll support in the direction of the pressing or contact movement or the disengaging or lift-off movement of the roll shell. The controlled-deflection roll is provided with a scraper device equipped with a scraper blade which, during operation, is in contact with the surface of the roll shell, and the scraper device is secured to the guide members.
