<p>In a method for manufacturing a material web (W) such as a fibre web, manufacturing two sub-webs (W1, W2) and joining said sub-webs (W1, W2) from open sides of the sub-webs (W1, W2). The apparatus for manufacturing the material web (W) such as a fibre web comprises a first forming surface (110a, 210a) for manufacturing a first sub-web (W1) and a second forming surface (120a, 220a) for manufacturing a second sub-web (W2) and a contact area (N1, N2, N3) for joining said sub-webs (W1, W2) from the open sides of the sub-webs (W1, W2). The system comprises the manufacturing apparatus of the material web (W) according to any embodiment of the invention and a processing apparatus of the material web (W) connected after it. A fibre material product (W), such as a reelable fibre web or sheet, comprises a first surface substance layer (11) and a second surface substance (12) formed of material components, which surface substance layers form outer surfaces of the fibre material product (W) on opposite sides of the fibre material product (W), and the material components of each surface substance layer (11, 12) are evenly distributed in each surface substance layer in the thickness direction of the surface substance layer.</p> |
