Abstract: Machine elements having Release Coatings that are Electromagnetic Wave Energy Cured, Highly Abrasion Resistant, Flexible, Low Friction, Release Coatings for Compliant Elastomeric Substrates used on Bowed Rolls and Press Rolls. 100% solids, highly abrasion resistant release coatings which are polymerization cured with electromagnetic wave energy in the wave length range of 5500 .ANG. to 0.006 .ANG.. These coatings will bond securely to commonly used structural and elastomeric, rigid and flexible, substrates; including metallic and non-metallic materials. The coatings are compositions of varying percentages of 2-Phenoxyethyl Acrylate, Tetraethylene Glycol Diacrylate, Isobutyl Benzoin Ether, 1,6 Hexanediol Diacrylate, Cycloaliphatic Bis A Epoxide, Polyurethane Acrylate, Methyl Methacrylate, Polysiloxane and other Acrylics, Tertiary Amines, Epoxidized Novolac, Fluorinated Alkyloxylate, Electromagnetic Wave Energy sensitive Photoinitiators, and Electromagnetic energy absorbers.

Abstract: A liquid-lubricated roll has an annular roller element rotatably supported by anti-friction bearings on an elongated axle which is longitudinally curved. Liquid lubricant for the bearings is supplied to an annular passageway between the roller element and the axle. During rotation of the roller, the liquid forms into a thin annular layer on its inner surface, which is agitated by projections on the axle to produce a lubricating mist.Barrier rings placed adjacent to the bearings are adapted to permit liquid to flow along the passageway while the roll is rotating, but to block flow of liquid above a selected level when the roll is stationary. This maintains a more uniform longitudinal distribution of liquid within the roll during periods of disuse, so that none of the bearings will be flooded when rotation starts, and a saving in power consumption and bearing life will therefore be realized.

Abstract: A roll section, i.e., a spool and bearing assembly for supporting a roller sleeve, has a cylindrical spool laminated of rolled sheets. Axially-extending seams of the different laminates are arranged relative to one another to balance the assemblage. Retaining elements within the spool engage the bearing to lock it in place.

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.
