Abstract
A method and apparatus for adjusting a set of bending rolls which simultaneously position a pair of adjustable top bending rolls with respect to a bottom bending roll. A bottom bending roll is mounted within a housing while a pair of adjustable top bending rolls is mounted on a frame. A pivot shaft is rotatably mounted on the housing with eccentric portions of the pivot shaft coupled to the frame. Rotation of the pivot shaft causes the simultaneous adjustment of the pair of adjustable bending rolls with respect to the bottom bending roll.
