ABSTRACT:
An apparatus for cleaning printing cylinder comprising a cleaning head 3 is disposed in parallel to the printing cylinder so as to be attachable and dettachable to the overall width thereof, and the cleaning is carried out by pressing said cleaning head 3 against the printing cylinder 1. The cleaning head 3 comprises a cleaning case 9 having a suction port 8 at the upper part thereof and a wind chest 10. The interior of the cleaning case 9 is partitioned into the front 11, the rear 12, and the middle part 13 with respect to the direction of the rotation of the printing cylinder 1, with the front 11 and the rear 12 being, respectively, fitted with cleaning members 14, 15 and the middle part 13 being fitted with a lip 16 composed of an elastomeric material. Between the lip 16 and the front 11 and beneath the rear 12 there are formed slits 17, 18 which have suitable gaps, and both of them communicate with the wind chest 10. The cleaning is carried out by supplying the cleaning liquid from the supply port 19 to the cleaning members 14, 15. The air carrying the waste cleaning liquid is collected in the wind chest 10 through the slits 17, 18 and sucked by a vacuum apparatus.
