ABSTRACT:
A process and apparatus for removing ink particles from an inked paper product which includes a conveyor for conveying the paper product along a path, the conveyor being constructed of a semi-permeable material that passes the ink particles while retaining the paper product. Vacuum boxes are positioned proximate to a first side of the conveyor for establishing a pressure differential across the conveyor and across a first segment of the path to draw the ink particles from the paper product through the conveyor. Shower heads on a second side of the conveyor directed a liquid toward the conveyor and on to the paper product as the paper product is advanced along the second segment of the path. Blocking members are positioned on the first side of the conveyor opposite the shower heads for substantially preventing the establishment of a pressure differential across the conveyor and across the second segment of the path and for preventing flow of liquid and ink particles through the conveyor across the second segment of the path.
