ABSTRACT:
An apparatus for slitting sheet material to a desired width includes laterally spaced circular slitter knives each fixed to a hub mounted on a rotatable shaft, each said hub being an hydraulic hub adapted to be expanded to permit axial movement on the shaft by injecting hydraulic fluid into an annular groove in the inside diameter of the hub. The novel feature comprises spacer rollers between the slitter knives to support the sheet material, these spacer rollers being arranged in cooperating pairs with each spacer roller comprising an annular hub portion with a plurality of equally spaced projections extending in an axial direction from at least one annular face of said hub. The projections are adapted to slidably mate with like projections of a cooperating spacer roller and each spacer roller hub is adapted to be expanded to permit axial movement thereof on the shaft by injecting hydraulic fluid into an annular groove in the inside diameter of the spacer roller knife hub.
