Abstract:
An oscillation apparatus for an oscillating roller, comprising:an oscillation mechanism for reciprocating an oscillating roller which can be rotated in a circumferential direction and can be reciprocated along an axial direction; an oscillation-width adjustment mechanism for adjusting an oscillation width of said oscillating roller; an oscillation-mechanism drive motor for operating said oscillation mechanism; an oscillation-width adjustment motor for operating said oscillation-width adjustment mechanism; oscillation-width control means for controlling operation of said oscillation-width adjustment motor such that said oscillation width of said oscillating roller attains a designated value; and oscillation-number control means for controlling operation of said oscillation-mechanism drive motor, on the basis of the number of revolutions of a plate cylinder, such that the number of oscillations of said oscillating roller per unit number of revolutions of said plate cylinder attains a designated value.
