ABSTRACT:
A web-forming method and apparatus to be used in the manufacture of paper. A web is formed at one side of a travelling wire while at the opposite side thereof, from a location in close proximity thereto, jets of steam are directed toward the wire to produce an implosion at the opposite side of the wire, as well as directly in the wire and in the web. The jets of steam issue from openings in the wall of an enclosure which is situated in close proximity to the said opposite side of the wire, this enclosure having in its interior steam which issues through the openings to form the jets. A plurality of these enclosures may form part of a forming board, and also one or more of the enclosures may be situated along the wire at a part thereof which has travelled beyond the forming board.
