<p>An apparatus (1) and method for aligning flexible printing plates (251), and for accurately drilling pin register holes (191) therein, includes a three way adjustable table top assembly (23) which can be selectively adjusted in X and Y directions, and rotated about an axis. A pneumatic clamp (253) is positioned on the table top assembly (23) for clamping a pre-marked flexible printing plate (251) to be drilled in place thereon. A movable stereomicroscope viewer (232) is slidable above the table top assembly (23) to view the flexible plate (251) for position adjustment via the adjustable table top assembly (23). A drill assembly (91) is positionable over each location at which a pin register hole (191) is to be drilled. The drill assembly (91) includes a movable hollow core drill bit (75) surrounding a stationary rod (181). Once the flexible plate (251) is aligned via the viewer (232), the drill assembly (91) is sequentially positioned above the flexible plate (251) at each point to be drilled with a pin register hole (191).</p> |
