ABSTRACT:
An improved mechanism for cleaning the driven roller in a printing press is described. In the mechanism, a wash cloth may be fed from a magazine roller over a pressure roller to a take-up roller. The pressure roller may be brought to bear against the surface of the cylinder with the wash cloth therebetween. The wash cloth is wet by spraying cleaning fluid thereon immediately prior to its encountering the pressure roller. The wet wash cloth is thus brought into contact with the surface of the cylinder which is then rotated against the cloth to cleanse the surface. After the surface is clean, dry cloth may be brought into contact with the cylinder by merely not activating the fluid spray. Means are provided for driving the pressure roller through a constant angle at each change of the cloth and, via a slip clutch, for maintaining a consistent tension on the cloth regardless of the length of cloth collected on the take-up roller.
