ABSTRACT:
An apparatus for mounting a plate on a plate cylinder includes a pair of right and left support levers, a pair of right and left arms, a plate press roller, a plate press pad, and a spring member. The pair of support levers are supported on a support shaft and driven to swing the support shaft. The support shaft is provided close to a circumferential surface of the plate cylinder to extend parallel with the axial direction thereof. The pair of arms are pivotally supported on the support shaft to be close to the pair of support levers. The plate press roller has two ends pivotally supported on the pair of arms and urges the plate against the circumferential surface of the plate cylinder when the plate is to be wound on the plate cylinder. The plate press pad is fixed on a holding member to couple free end portions of the pair of support levers, and has an elastic surface for pressing a trailing-side of the plate. The spring member is interposed between the free end portion of at least one of the support levers and a free end portion of at least one of the pair of arms.
