Title (EN) VARIABLE FREQUENCY FOURDRINIER GRAVITY FOIL BOX
(FR) ENSEMBLE DE CAISSE D'EGOUTTAGE A TABLE PLATE A FREQUENCE VARIABLE
Abstract: front page image
(EN)A variable frequency foil (VFF) box assembly (36a', 36b', 36c') and mechanisms for moving individual foils/foil beams and individual foil beam sets relative to each other to adjust the frequency of a paper making machine, and method of use are provided. The VFF box assembly (36a', 36b', 36c') allows for continuously and uniformly adjusting the pitch distances (x) of individual foils within foil sets over a finite range, and also adjusting the distance (2x) between foil sets during the continuous operation of a paper making machine.
(FR)L'invention concerne un ensemble de caisse d'égouttage à fréquence variable (VFF) (36a', 36b', 36c') et des mécanismes permettant de déplacer des lames individuelles ou des séries de lames les unes par rapport aux autres afin d'ajuster le rendement d'une machine à fabriquer le papier, ainsi qu'un procédé d'utilisation de cet ensemble. Cet ensemble (36a', 36b', 36c') permet d'ajuster de façon continue et uniforme le pas (x) des lames individuelles des séries de lames sur une plage donnée, et également d'ajuster la distance (2x) séparant deux séries de lames, durant le fonctionnement en continu de la machine à fabriquer le papier.
