There is disclosed a pressure pad used in an apparatus for cleaning the outer surface of a cylinder with a cleaning fabric. The cleaning fabric is directed between the pressure pad and the cylinder, the pressure pad having opposite side edges which are fixed in the apparatus to extend parallel to the cylinder. The pressure pad is made of elastomer and curved between the opposite side edges thereof to be convex toward the outer surface of the cylinder. The pressure pad cooperates with the cleaning fabric so that the cleaning fabric can be pressed against the outer surface of the cylinder by the pressure pad to clean the outer surface of the cylinder. The pressure pad comprises an engaged portion engaged with the cleaning fabric so that the cleaning fabric is sandwiched between the engaged portion and the cylinder to be pressed against the outer surface of the cylinder. The pressure pad further comprises a pressure imparting portion positioned between the engaged portion and at least one of the opposite side edges of the pressure pad for imparting a pressure between the engaged portion and the cylinder. The pressure imparting portion is different in mechanical parameter from the engaged portion.

Pressure pad and cylinder cleaning apparatus

A cylinder cleaning device for use with a cleaning fabric supply element having an outer surface comprises a frame and a receiving and supporting member connected to the frame for supporting the outer surface of the cleaning fabric supply element.

Cylinder cleaning device

There is disclosed a device for cleaning the cylinder of a printing press with a cleaning fabric. The device comprises a pad including a surface opposed to the cylinder. The cleaning fabric is directed between the surface of the pad and the cylinder, the surface of the pad being at least partially uneven. The device further comprises means for moving the surface of the pad toward the cylinder so that the cleaning fabric is pressed against the cylinder by the pad to clean the cylinder.

Cylinder cleaning device and cleaning method

A method of cleaning the outer surface of a cylinder by using a cleaning fabric intermittently fed from a supply, and engaged with and pressed against the outer surface of the cylinder. The method includes predetermining periods for each of which the cleaning fabric is engaged with the outer surface of the cylinder a time so that at least some of the periods are different in length from other periods in a cleaning cycle.
