ABSTRACT:
A drill (10) for flexographic plates and negatives includes a table (15) movable in a Y direction under a drill bar (30), and a pin bar (25) movable in an X direction on the table so that negatives can be supported on the table, moved to an appropriate positon underneath the drill bar, and held in place by clamping the table and the pin bar. Drill bar (30) moves up and down and rotates a linear array of hollow spindles (35) holding hollow drill bits (40) for boring a suitable array of holes. The same array bored in the negatives is then bored in a flexographic plate corresponding to each negative, and these are pinned together while the plates are imaged. Drill (10) includes slug rods (32) extending downward through spindles (35) and bits (40) to push out drilled slugs when the drill bar raises. The spindles are preferably rotated by a drive chain (55).
