Pressure pad and cylinder cleaning apparatus

摘要

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.
