Abstract
A form roller apparatus for a printing press includes an ink form roller, compression coil spring, bolt, and U-groove. The ink form roller is in contact with an oscillating roller, and slides in an axial direction to follow motion of the oscillating roller in an axial direction. The ink form roller has a roller shaft which is supported rotatably and a roller main body which is supported to be movable in the axial direction of the roller shaft. The compression coil spring biases the roller main body in the axial direction. The bolt moves forward/backward in a radial direction at an end of the roller shaft. The U-groove is provided to the roller main body and is engaged by the bolt to regulate slide motion of the ink form roller in the axial direction.
