Abstract (en)
[origin: WO2004065688A1] The device comprises: a fiber distribution head (3); a forming wire (9) movable underneath the said head in a feeding direction (f 9); a suction box (7) located on the opposite side of the forming wire (9) to the head (3) and connected to a suction system. The suction box (7) is divided transversely with respect to the direction of feeding of the forming wire (9) into at least two longitudinal sections, extending in the direction of feeding of the forming wire. Moreover, control members (29) are envisaged for controlling suction in each of the longitudinal sections in an independent manner with respect to the other longitudinal sections.
