Abstract (en)
[origin: US4444480A] A drum processing apparatus for sheet or web material is described wherein the drum also acts as a solution recirculating means. The apparatus comprises a vessel containing processing liquid in which is partially immersed a driven drum which guides the sheet or web material through the vessel. The drum comprises within its body at least one cavity, there being at least two apertures which lead from said cavity to the outside of the drum. The cavity is so formed and the apertures are so located that, when the drum rotates, a body of liquid from the vessel enters the cavity through one aperture at a lower level in the vessel, is raised to a higher level in the vessel, and leaves the cavity at the higher level through the other aperture. Thus the liquid is circulated in the vessel.
