<p><P>PROBLEM TO BE SOLVED: To provide a driving apparatus which has both characteristics of a rigid roller hardly deformed and characteristics of a flexible roller capable of enlarging its friction, and can compensate for their defects, in an ink roller driving apparatus in a rotary press and in a flat-bed press. <P>SOLUTION: In the ink roller driving apparatus constituted so that an ink roller for transferring an ink onto a plate cylinder or a plate bed on the surface of which printing information is formed is rotatably driven through a rotation transmitting mechanism, the rotation transmitting mechanism is constituted by a following roller provided coaxially to the ink roller and a driving roller driving the following roller. Either one roller of the following roller or the driving roller is constituted by providing the flexible roller and the rigid roller coaxially, and the radius of the flexible roller is made a little larger than the radius of the rigid roller. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
