Abstract
An apparatus for drilling holes in flexible materials used for flexographic printing includes a table which receives single sheets of flexible material which are to be drilled by a downwardly moveable drill. An optical mirror, TV-camera and monitor serve as viewing means to directly view the exact position on the surface of the material to be drilled. The optical mirror occupies a first position between the moveable drill and the flexible material, the first position being directly below the drill and directly above a target location on a single sheet. The optical mirror is retractable to a second position away from the path of the moveable drill, the optical mirror being replaced in the first position after the drilling is accomplished.
