The invention relates to a method of making a structured fibrous web (W). The method comprises forming a fibrous web (W) and conveying the formed fibrous web on a water receiving felt (5) to a dewatering nip (PN) formed by a first press unit (8) and a second press unit (9) and where an endless belt (11) is passed through the nip together with the fibrous web 5 (W) and the water receiving felt (5), The endless belt has a side which is covered by a polymer and which contacts the fibrous web (W) in the dewatering nip (PN). After the dewatering nip, the web (W) is transferred with a speed difference to an endless structured clothing (12) which is permeable to air and has protruding knuckles (40) on the side that contacts the fibrous web (W) and which protruding knuckles (49) give the structured clothing (12) a topographic surface 10 area which, for a given length of the structured clothing (12) in the machine direction and a given width of the structured clothing in the cross machine direction, exceeds the plain surface area of a part of the endless belt (11) having an equal length and width. The structured clothing is operated at a speed which is so much lower than the speed of the endless belt (11) that the relative difference in speed between the endless belt (11) and the structured (12) fabric 15 corresponds to the relative difference in surface area between the endless belt (11) and the structured clothing. In this way, the fibers of the fibrous web (W) will be evenly distributed on the structured clothing (12). The invention also relates to a creped fibrous web (W) having a basis weight in the range of 14 g/m.sup.2-40 g/m.sup.2, and having a three-dimensional structure formed by depressed regions (45) and elevated regions (46). The fibers of the fibrous web (W) are 20 evenly distributed over the surface of the creped fibrous web (W).

According to an example aspect of the present invention, there is provided an apparatus and a method comprising a forming section for feeding an aqueous furnish of fibres on a moving surface to form a shape of a product and a pressing and heating section for removing water from the shaped product received from the moving surface. The pressing and heating section comprises a felt and metal belt that are set to run against each other for receiving the furnish from the moving surface and heating elements for heating the web in at least two pulses including at least one first pulse wherein the product is pressed for at least 10-200 ms on a first pressure and at least one second heating and smoothing pulse wherein the product is heated at least for 10-200 ms on a pressure that is higher than the first pressure, and at least one of the surfaces pressing the product being the smooth metal belt.

A method for producing a fibrous material web, particularly for producing a tissue or hygienic paper web, in which a fibrous suspension is dewatered in a crescent former to obtain a fibrous material web, and dried on a Yankee. After the crescent former, the fibrous material web is guided along with the forming screen and felt over a suction roller downstream of the forming roller. A device for carrying out the method for producing a fibrous material web.

The invention relates to a forming section (2) for forming a fibrous web (W). The forming section (2) comprises a first forming fabric (3) arranged to run in a loop supported by guide elements (4) and a second forming fabric (5) arranged to run in a loop supported by guide elements (4). The second forming fabric (5) is arranged so in 5 relation to the first forming fabric (3) that the two forming fabrics (3, 5) converge towards each other to form an inlet gap (6) into which stock can be injected. A forming roll (7) is arranged within the loop of the second forming fabric (5) to guide the second forming fabric (5) into the inlet gap (6) and to guide the first and the second forming fabric (3, 5) along a part of their path which is common to both the first and the second 10 forming fabric (3, 5) and which begins at the inlet gap. The forming roll (7) comprises a flexible tubular jacket (8) which is arranged to run in a loop around an axis of rotation (A) that extends in a direction perpendicular to the direction in which the first and second forming fabric (3, 5) are arranged to run and the forming roll further (7) comprises a support ledge (9) located inside the loop of the flexible tubular jacket (8) 15 and extending in a direction parallel to the axis of rotation (A) of the flexible tubular jacket (8). The support ledge (9) can press the flexible tubular jacket (8) in a direction outwards away from the axis of rotation (A) such that, in the area in which the flexible tubular jacket (8) is pressed outwards by the support ledge (9), the flexible tubular jacket (8) is caused to follow a path with a radius of curvature which is smaller than the 20 radius of curvature of the flexible tubular jacket (8) outside this area. The invention also relates to a method of forming a fibrous web.
