Abstract
To positively lock in position a pair of eccentrically journalled blanket cylinders (3, 6), movable between three positions, namely in engagement with a first pair of plate cylinders (1, 4), or a second pair of plate cylinders (2, 5), or in engagement with neither plate cylinder, the blanket cylinders having a printing substrate passed therebetween for perfecting printing, the eccentric bearings (7, 8) for the blanket cylinders are secured to operating disks (9, 10) which, each, are coupled to a scissor-link arrangement formed by two pairs of links (16, 18; 17, 19), joined at a common pivot point. Pneumatic cylinder-piston arrangements move the pivot points (1618, 1719) to compress one of the scissor link pairs to V position, while the other link pair is moved to slightly over-center in-line position for a toggle or locking effect; when both scissor link arms are in half-open V position, the blanket cylinders are disengaged from the plate cylinders. Abutment stop means, located between the blanket cylinders, receive the pivot points, when the link arms are in essentially in-line or toggle position, and adjustment bolts (42, 43, 44, 45) can control the position of the scissor link arms, when in V position for accurate adjustment of the locked position of the blanket cylinders.
