<p>A rotary cutting die assembly is comprised of a support roll having a cylindrical exterior surface with a first axial slot formed in the exterior surface and extending a first depth into the support roll, and a second axial slot formed in the exterior surface adjacent the first slot and extending a second depth into the support roll, the second depth being less than the first depth. A cutting blade, shim and lock-down bar are received in the first slot of the support roll. The lock-down bar supports a plurality of set screws oriented at an acute angle relative to the cutting blade. Tightening the plurality of set screws in the lock-down bar causes the set screws to urge the cutting blade and bar apart from each other and into friction engagement against the opposite sidewalls of the first slot, thereby securing the cutting blade and mounting bar in the first slot. Loosening the plurality of set screws enables the cutting blade to be quickly and easily removed from the first slot for adjustment of the blade position or replacement of the blade.</p> |
