Abstract
The adjustable-curvature roll of the present invention includes a hollow, cylindrical axle in which two rods are inserted. Each of these rods is securely fastened to an endplate at one end of the axle, and the opposite end of each rod is threaded within one of two oppositely rotating intermeshed gears. An adjusting hexagon or other similar adjusting device is connected to one of the meshed gears and the turning of the adjusting device in one direction causes an increase in the compression applied to one of the rods while at the same time exerting an increased tension on the other rod which is connected to the oppositely rotating gear. This combination of tension and compression causes the curvature of the roll to change. An indicator attached to the adjusting device provides a reading of the chosen degree of curvature. The axle may be surrounded by an outer sleeve which rotates, through the aid of ball bearings, around the axle.
