<p>A multi-ply paper web forming apparatus utilizes first and second forming wires (12,14) which travel in a co-running path for a portion of their length and which form a throat (8) into which an aqueous slurry of paper pulp fibers is introduced. The slurry is dewatered between the co-running first and second forming wires (12,14) upwardly and downwardly to quickly produce a substantially formed, but still moist, top ply web (WT) which is carried on the second forming wire (14) onto a base ply web (WB) which has previously been formed on the wire (10) of a single wire former. The first surface of the top ply web (WT) is brought into ply bonding engagement with the surface of the base ply web (WB) to produce a composite multiply web (WC) which has superior overall ply bond, retention and dryness before leaving the web forming section of a papermaking machine.</p> |
