Abstract

Washing device for cleaning a cylinder of a printing machine includes a brush roller formed with bristles and rotatably driven about an axis, the brush roller cooperatively engaging the cylinder, a device for feeding washing fluid to the bristles for self-cleaning the bristles, and a deflection element disposed in a rotational region of the bristles, fixed in position relative to the brush roller and extending along the length of the brush roller, the bristles yieldingly brushing against the deflection element as the brush roller is rotated so as to be bent temporarily and subsequently returned to a straight extended position thereof, the deflection element being formed as a distributor pipe connected to the feeding devices and having outlet openings formed therein for directing the washing fluid radially towards the axis of the brush roller.
