A method for forming a fibrous web, comprising the steps of:
- (a) forming a first slurry comprising fibers in an aqueous dispersion medium;
- (b) forming a second slurry comprising fibers in an aqueous dispersion medium;
- (c) moving a first foraminous element in a first path;
- (d) moving a second foraminous element in a second path, a nip area provided at a location along the first and second paths;
- (e) passing the first slurry into contact with the first foraminous element moving in the first path;
- (f) passing the second slurry into contact with the second foraminous element moving in the second path;
- (g) passing a third material between the first and second slurries, wherein the third material does not contact the foraminous elements, and wherein the third material is introduced at a plurality of points;
- and
- (h) withdrawing liquid from the first and second slurries and third material through the first and second foraminous elements, respectively, to provide a fibrous web.
