ABSTRACT:
In a cleaning device for a blanket cylinder in an offset lithographic printing press, there are provided a power-rotated cleaning disc having a front surface partly in contact with the cylindrical surface of the blanket cylinder, a tank associated with the cleaning disc for storing and supplying a predetermined quantity of a cleaning liquid to the cleaning disc, and a lateral feed mechanism for driving the cleaning disc in reciprocating motion transversely along the cylindrical surface of the blanket cylinder, whereby the latter surface is cleaned while the blanket cylinder is rotated at a low speed.
