Abstract
A measuring element which senses the running of the solid of rotation is connected to the actual value input of a controller whose output signal is connected to a control element which acts upon a bearing which is adjustable perpendicularly to the axis.
Claims4
An arrangement for keeping the nip between two rolls at a constant width comprising an adjustable bearing supporting one of said rolls at either end, said adjustable bearing is adjustable perpendicularly to its axis of rotation in a first direction toward and away from the other of said rolls as well as in a second direction perpendicular to said first direction, a measuring means which senses the running of the rolls at their peripheral surface, a controller which has an actual value input and a target value input, and which is connected to the measuring means at the actual value input, and a control element which is actuated by the controller and which acts upon said adjustable bearings so as to keep the width of said nip constant despite eccentricitites of the bearing supporting the rolls and of the shape of said rolls.
