Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A dampening water circulation system achieves further lightweighting, easy maintenance and decreases a heat energy influencing the temperature of the dampening water. There are provide a dampening water supply pipe 50 and the dampening water pool bar 60 along the water fountain roller 20. The dampening water pool bar and the water fountain roller are arranged to maintain an aperture G of several mm to thereby form the water pool portion 70 between two members. The fed water can be kept in the dampening water pool portion to be applied on the water fountain roller. The dampening water pool portion is made small in size to minimize a time for the dampening water from the supply pipe 50 to the water fountain roller whereat the supplied water does not influenced by any foreign element, which can minimize the return water amount and is effective to decrease the cooling capacity for the used dampening water.
