Abstract:
The present invention relates to a method for manufacturing a multiply web composite. The method comprising the steps of mixing natural fibers (2), plastic particles (3) and liquid (4) to form a liquid mixture (10); transporting the liquid mixture to a forming section (6, 7) of a paper machine; transporting a first fiber suspension (11) to the forming section; transporting a second fiber suspension (12) to the forming section; forming a multiply web (13), wherein the first fiber suspension forms a first ply (15), the liquid mixture forms a second ply (16), and the second fiber suspension forms a third ply (17), wherein the second ply is arranged between the first ply and the third ply; and removing liquid from the multiply web to form the multiply web composite, such that, the first and third plies comprising natural fibers and the second ply comprising natural fibers and plastic particles.
