ABSTRACT:
A die roll and air manifold system comprising a rotary die roll rotatable in a press, and an air manifold having a cylindric body positioned in a central bore in the die roll. The cylindric body of the air manifold has an outside diameter only slightly less than the diameter of the bore. A pair of shafts extend coaxially from opposite ends of the cylindric body beyond respective ends of the die roll for mounting of the air manifold and die roll on a press. The manifold shafts have outside diameters less than the diameter of the central bore in the die roll and less than the outside diameter of the cylindric body of the air manifold. Axial passaging in the air manifold is provided for connection at its inlet end to a source of pressurized air. One or more air outlet passages in the body of the air manifold extend from this axial passaging to the outer surface of the manifold body. These passages are positioned for intermittent alignment with radial outlet passages in the die roll as the die roll rotates relative to the air manifold thereby to effect the intermittent delivery of bursts of pressurized air through the air outlet passages in the die roll to remove scrap material from cutters on the outer surface of the die roll.
