Abstract
An adjustable-bow bar or roll axle, useful for spreading slit sheets of paper and for other purposes, includes a hollow cylindrical shell. Two tension bolts extend along axes parallel to the centerline of the shell, and interconnect the ends of the bar or axle. One of the bolts lies in a plane of desired curvature of the bar and applies a bending moment to curve the bar in this plane; this bolt may be located inside or outside the shell, depending on the required bending moment. The second bolt may be inside the shell; its angular position is adjustable with respect to that of the first. This bolt is set in the plane of a resultant force applied to the bar by the tension in the sheet, and applies a bending moment to offset this force and prevent curvature of the bar in this plane. A third bolt may be located in a vertical plane to apply a bending moment to prevent curvature of the bar by its weight; or the second bolt may serve this purpose also.
