  • Patent number: 4082037
    Abstract: A cleaning roller having a soft fibrous surface (such as lamb's wool roller) is disposed ahead of the blanket cylinder of an offset press, the surface presenting a nap which swells upon rotation of the roller to wipe particulate matter (dusting powder or residue particles) from the paper sheets before the same are printed. A trough containing water (in which the particles are soluble) extends parallel to the roller and receives the particles stripped from the roller by a doctor blade. The removed particles are directed from the blade to the trough by a guide surface continuous with the blade which is presented by a specially shaped sheet member extending from the blade into the trough. The water may be recirculated by a pump, or supplied and drained at a rate to prevent the particles from accumulating.
