Abstract

PURPOSE: To knead an ink and achieve the smooth feedback of the surplus dampening water from a plate cylinder to a dampening water storage by using a dampening water storage space section comprising a metering roller and an external face and a roller's edge section of a dampening roller, and a horizontal swing roller swinging in concert with a surface roller. CONSTITUTION: Dampening water in an upper triangular space section between a metering roller 3 and a dampening roller 4 is enclosed by a sealing device on the edge of the roller. The dampening water volume which is adjusted by the reciprocal roller's pressure using an operation section material 14 passes a first contact region 20 of the roller and is fed by the side of the dampening roller 4 to a plate cylinder 2. A dampening device is provided with a gear drive device to drive a pair of rollers comprising a metering roller 3 and dampening roller 4 and the gear drive device drives a metering roller 3 at a circumferential speed faster than that of the plate cylinder 2. The rotation and horizontal movement of a horizontal swing roller 5 is effected by friction cause by a metering roller and an axis of the horizontal swing roller 5 is built in an elongated hole 24 for a bearing 7 so that said axis may not be rotated. An axis 23 is press-fitted by an adjustment screw 25 to a compression spring 26.
