A retro-fit roller die apparatus for supporting pairs of roller dies in predetermined clearances for processing a web workpiece, and for varying the clearances between the dies to accommodate variations in the thickness of web material and having first and second roller dies rotatably mounted on respective roller die bearings, one of the first and second roller dies being moveable both upwardly and downwardly transversely to its axis of rotation, and being moveable axially along its axis of rotation, thereby achieving adjusting of the die clearance between the first and second roller dies in two planes. The two adjustments take place simultaneously so as to cause an adjustment movement in a diagonal direction, as between one die and the other in each pair.
