Rotary Die Axis Synchronization System and Adjustable Wedge Apparatus Therefor

An adjustable wedge apparatus comprising a split wedge, a first block, a second block, a threaded adjustment screw, and an expandable and contractable biasing device, wherein:

• the split wedge is configured to be sandwiched between the first block and the second block;
• the first block and the second block are configured to be held together, with the split wedge between, by the expandable and contractable biasing device;
• the split wedge has a blunt end, a narrow end, a recess, a through-hole, and a pair of through-slots, the recess having an opening at the narrow end, extending toward the blunt end, having a recess bottom, and dividing the narrow end into two tines, the through-hole extending from the blunt end to the bottom of the recess and having an internal thread, the pair of through-slots at least partially straddling the recess and respectively extending along the tines;
• the threaded adjustment screw has an external thread that is complementary to the internal thread of the through-hole;
• each of the first block and the second block has a pair of projections configured to align respectively with the pair of through-slots, for catching the biasing device;
• and
• each through-slot of the pair of through-slots, and the biasing device, are configured such that the biasing device can pass through either through-slot and catch one of the projections of the first block and one of the projections of the second block.
