A device for cleaning printing rollers. This device is capable of effectively cleaning rollers through a brushing process and a washing-drying process, the former process being conducted in a liquid-cleanser-contained tub wherein a sandpaper-brush or a wire-brush makes a pressing contact with a roller to be cleaned in the state that said brush rotates around a vertical axis simultaneously moving to and from axially along the roller, the roller resting on a pair of parallel rollers keeping a suitable distance between them and being disposed axially parallel with the roller to be cleaned, the pair of rollers in this state transmitting their motorized rotation to the roller to be cleaned so as to add to the brushing effect, the brushed roller thence being placed under a washing-and-drying process at the other tub wherein a showering device and a blade function effectively for the washing and drying work respectively.
A device for cleaning printing rollers, said device comprising means supporting and rotating a roller to be cleaned, a disc-shaped cleaning member having an axis of rotation perpendicular to the axis of a roller mounted on said device and positioned to make pressing contact with the outer periphery of a roller positioned on said supporting and rotating means, means to rotate said cleaning member about its axis, and means to move said cleaning member along the outer periphery of said roller while in pressing contact with a roller simultaneously with said cleaning member rotation.
