| 摘要 |
<p>The invention concerns a forming-gap arrangement in a twin-wire former of a paper machine. The twin-wire former comprises forming wires (10,20) operating one against the other, which forming wires (10,20) define a wedge-shaped narrowing forming gap (G) between them. The forming-gap arrangement comprises two opposite support members (40, 41), whose inner sides have been arranged as direct extensions of the inner sides of the lip walls (31,32) of the headbox that define the discharge duct. The support members (40,41) have been arranged to extend into the forming gap (G) as parallel to one another, so that the free ends (42) of the support members (40,41) are placed at direct proximity of, or in contact with, the forming wires (10,20). The support members (40,41) have a plate-like, isotropic or anisotropic, at least to some extent resilient construction. <IMAGE></p> |
