ABSTRACT:
A rolling device or roller mill having a controlled-deflection roll possessing a stationary roll support or carrier mounted in a frame of the rolling mill. A tubular roll shell is rotatable about the roll support and bears thereon by means 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 disengaging movement of the roll shell. The controlled-deflection roll is equipped with a scraper device having a scraper blade which, during operation, is in contact with the outer surface of the roll shell, the scraper device being rotatably mounted on the frame. At least one of the guide members has a disengaging or lift-off element which, when the roll shell performs a disengaging or lift-off movement from the operative position, abuts a part of the blade support or carrier and raises the blade off the surface of the roll shell.
