Abstract
This adjustment mechanism (30) is for a printing press (10) providing a train of modules (12) driven by a common lineshaft (20) having a ninety degree (90.degree.) drive for a roll 18. The drive includes a worm (22) mounted to the lineshaft (20) engaging a worm gear (24) carried by the roll (18) such that axial movement of the worm (22) rotates the worm gear (24) and adjusts the register of the roll. The adjustment mechanism (30) includes a threadedly extensible member (50) engageable with one side of the worm (22) to urge the worm (22) in one direction and a compression spring (52) mounted on the other side of the worm (22) to urge the worm (22) in the opposite direction.
