  • Patent number: 4887494
    Abstract: A set of two saw benching rolls. Each roll has a surface divided into two sections. One section is in the form of a convex surface and the other is in the form of a concave surface. The rolls are mounted in an opposed relationship and are operable to apply pressure to a saw placed there between. By moving the two rolls axially and relative to one another in the various positions, the saw may be "leveled up" or "leveled down" to remove discontinuities. The benching rolls may also be used in the conventional manner to tension or to shear the saw.
