Abstract: A printing press comprises an oscillating roller capable of rotating circumferentially and moving axially in a reciprocating manner, and does rainbow printing on a sheet, supplied from a feeder, in a printing unit. The printing press includes an oscillation width control device and an oscillation frequency control device for exercising control such that the oscillating roller moves axially in a reciprocating manner when printing is started in a state in which the axially moving motion of the oscillating roller is at a standstill. The printing press can automatically start the oscillating motion of the ink oscillating roller when printing is started from the state of the oscillating motion of the oscillating roller being stopped at the time of ink conditioning in rainbow printing, thereby decreasing the number of defective sheets and improving the ease of operation.

Abstract: An inking apparatus controller includes an oscillating roller rotatable in a circumferential direction and reciprocatable along an axial direction thereof; an oscillation-width adjustment mechanism for adjusting an oscillation width of the oscillating roller; an oscillation-width adjustment unit for operating the oscillation-width adjustment mechanism; and a control unit for controlling operation of the oscillation-width adjustment unit such that the oscillation width of the oscillating roller assumes a designated value and for controlling operation of the oscillation-width adjustment means such that during cleaning work, the oscillating roller oscillates over an oscillation width which is set in a memory in advance.

Abstract: A rotary press includes a first motor for rotating a first rotary member; a second rotary member rotatable by the first motor and movable in an axial direction thereof; a second motor for moving the second rotary member in the axial direction and rotating the second rotary member; a connecting/disconnecting mechanism for permitting and stopping transmission of rotation from the first motor to the second rotary member; and a clutch for stopping transmission of rotation from the second motor to the second rotary member when the first motor is connected to the second rotary member by the connecting/disconnecting mechanism such that the first motor can rotate the second rotary member and for connecting the second motor with the second rotary member such that the second motor can rotate the second rotary member when transmission of rotation from the first motor to the second rotary member is stopped.
