ABSTRACT:
A bearing-block body member in which a die-cutting roll is journaled includes an adjusting cap seated in it through which a bore extends axially of the roll. An axial chamber is provided in the roll, and a stationary air manifold extends into the chamber, permitting relative rotation between the roll and the manifold. An air tube having an axial portion and a transverse portion has its axial portion extending through the bore in the adjusting cap to couple with the manifold so as to hold it in rotational position but permit axial withdrawal. Fluid communication is provided between the air tube and the manifold, and corresponding ports in the manifold and apertures in the die register periodically to permit air to flow from the air tube through the manifold, the ports, and the apertures to the outer surface of the roll. As a result of this arrangement, air can be supplied transversely of the axis of the roll, but ready removal of the roll and the manifold is afforded.
