<p>A printing cylinder/roller cleaning apparatus for a printing press includes a cleaning cloth (6), a take-up roll (14), a supply roll (8), a ratchet wheel (10), a lock lever (30), a swing lever (18), a one-way clutch (15), and an air cylinder (25). The cleaning cloth is pressed against a circumferential surface of a rotating printing cylinder/roller (2). The take-up shaft takes up the cleaning cloth. The supply roll supplies the cleaning cloth. The ratchet wheel is coaxially mounted on the supply roll. The lock lever engages with the ratchet wheel when the cleaning cloth is not taken up. The swing lever is coaxially mounted on the take-up roll 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 roll with the swing lever only in a direction to take up the cleaning cloth. The air cylinder pivots the swing lever in response to the cleaning operation of the printing cylinder/roller. <IMAGE></p> |
