Abstract
The apparatus is a spray shield to prevent ink and cleaning fluids from being spun off of the ends of printing cylinders. A cylindrical shield around the end of the printing cylinder is attached to a hub resting on the printing cylinder axle, and the hub and shield have sections held together by a hinge and a latch so they can be unlatched and removed for cleaning. An axial spring assembly is attached to the hub on the side opposite from the cylindrical shield so that the springs compress and friction is minimized if the hub is contacted by the printing cylinder.
