Abstract
A support structure for a plate cylinder is composed of a pair of support frames; a pair of eccentric slide bearings rotatably supported on the support frames; a pair of eccentric roller bearings rotatably supported by the eccentric slide bearings and rotatably supporting end portions of a shaft of the plate cylinder; dogs and pinions for rotating the eccentric slide bearings relative to the support frames in the same amount; an annular plate, a casing, a drive shaft, a worm wheel, a worm gear, a threaded shaft, a support member, a connecting rod, and a connecting pin for rotating one of the eccentric roller bearings relative to one of the support frames; and an annular plate, a connecting rod, and connecting pins for restraining rotation of the other eccentric roller bearing relative to the other support frame. The support structure prevents occurrence of a difference between the amounts of movement of the axis on the operation side of the plate cylinder and the axis on the drive side of the plate cylinder during adjustment of the printing pressure, thus preventing cocking of the plate cylinder.
