Abstract (en)
[origin: US5284093A] A rotatable plate cylinder (10) for supporting a printing plate (150) has an open passage (34) and a locking member (26) supported for movement in the passage (34). The locking member (26) is movable inward of the passage (34) to a closed position, and is movable outward of the passage (34) to an open position. The locking member (26) is subjected to a first centrifugal force which urges it to move outward from the closed position toward the open position when the plate cylinder (10) rotates. A balance member (28) is subjected to a second centrifugal force when the plate cylinder (10) rotates. Connecting pins (100) direct the second centrifugal force against the locking member (26) oppositely to the first centrifugal force.
