This invention is directed to an im- proved forming fabric for papermaking machines having a transverse nonwoven sheet contact layer (34) adhered to a base fabric layer (22) in order to better retain fines, the fluid flow passageways (42) be- tween adjacent structural members (36) in the nonwoven sheet contact layer being smaller than the fluid flow passageways in the adjacent base fabric layer and in fluid communication with the nonwoven sheet contact surface or the nonwoven surface adjacent to the base fabric, or both. The sheet contact layer may be comprised of fibers, filaments, monofilaments, open cell foam, or the like.
La présente invention vise une toile de formation améliorée pour machine à papier. La toile comporte une couche non tissée transversale (34) entrant en contact avec les feuilles et collée à un support textile (22) pour mieux retenir les particules fines. Les ouvertures pour l'écoulement de fluide (42), situées entre les éléments structuraux adjacents (36) de la couche non tissée, sont de plus petite dimension que les ouvertures pratiquées dans le support textile adjacent et communiquent avec la surface de contact non tissée ou la surface non tissée adjacente au support textile, ou avec les deux. La couche de contact peut être formée de fibres, de filaments, de monofilaments, de mousse poreuse ou d'autres matières semblables.
