Description

TECHNICAL FIELD

[0001] The present invention relates to an assembly of forming elements which together define in a papermaking apparatus a discontinuous supporting surface for a papermaking suspension to permit drainage and micro-turbulence to be accurately controlled, and to the papermaking apparatus per se. BACKGROUND OF THE INVENTION

[0002] In the papermaking industry, various forming elements are deployed to promote the drainage of water from paper stock in its transformation from a papermaking suspension (or slurry) of fibres, water and chemicals (eg fillers) into a self-supporting web of cellulose fibres commonly referred to as a sheet (ie a sheet of paper or board). De-watering takes place in the forming area at the “wet end” of a papermaking apparatus, a typical one of which is illustrated schematically by way of example in FIG. 1. Thus in FIG. 1, parallel papermaking wires 1 (or mesh or a belt) move in direction A and are supported from beneath by discrete forming elements ...
