DEVICE FOR DRY-FORMING A WEB OF FIBERS WITH AN INNOVATIVE SUCTION BOX, AND ASSOCIATED METHOD

摘要

The device includes: a fiber distribution head (3); Down in the f (9) on moveable forming net (9); The opposite side (7) of suction box is located at forming net (9) to head (3) and is connected to suction system. (9) that gettering container (7) is laterally with respect to forming net feeding direction are divided into the forming net extended on the feeding direction at least two vertical sections. Moreover, control member (29) is envisaged for control sucking in section longitudinally in each in an independent way relative to another longitudinal sectional drawing.
