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.
In an apparatus for drilling holes including a table mounted on a stationary base, a drill attached to supporting means located adjacent the table and mounted perpendicular to and aligned toward the table, and means for providing movement of the table and the supporting means relative to one another, the improvement comprising a mirror interposed between the drill and the table, such that a line intersecting said mirror and the drill is perpendicular to the table, said mirror being retractably mounted on the supporting means, and a video imaging system aligned with said mirror.
A process for locating a hole target on a material and drilling a hole at said hole target using an apparatus having a table mounted on a stationary base, a drill attached to supporting means located adjacent the table and mounted perpendicular to and aligned toward the table, means for providing movement of the table and the supporting means relative to one another, a mirror interposed between the drill and the table, such that a line intersecting said mirror and the drill is perpendicular to the table, said mirror being retractably mounted on the supporting means, and a video imaging system aligned with said mirror, the process comprising mounting said material on the table, the material having a hole target defining the location to be drilled;
