ABSTRACT:
A printing cylinder/roller cleaning apparatus for a printing press includes a cleaning cloth, a take-up shaft, a supply shaft, a ratchet wheel, a lock member, a swing lever, a one-way clutch, and an air cylinder. The cleaning cloth is pressed against a circumferential surface of a rotating printing cylinder/roller. The take-up shaft takes up the cleaning cloth. The supply shaft supplies the cleaning cloth. The ratchet wheel is coaxially mounted on the supply shaft. The lock lever is engaged with the ratchet wheel when the cleaning cloth is not taken up. The swing lever is coaxially mounted on the take-up shaft and rotated to actuate the lock lever, thereby releasing engagement between the ratchet wheel and the lock lever. The one-way clutch connects the take-up shaft with the swing lever only in a direction to take up the cleaning cloth. The air cylinder pivots the swing lever in response to a cleaning operation of the printing cylinder/roller.
