Abstract: A belt (10) for a fiber web machine has an inner surface (11) and an outer surface (12). A plurality of parallel dewatering grooves are arranged in a first direction (D1) on the outer surface (12) of the belt (10), each dewatering groove having a width. A first dewatering groove (21) has shallow portions (30) having a first depth (32), and deep portions (40) having a second depth (42), which first and second depths (32, 42) are determined from the outer surface (12) of the belt (10) in a depth direction, wherein the first depth (32) is smaller than the second depth (42).

Abstract: An industrial textile has a double warp. Yarns (111, 112) of a first warp and yarns (131, 132, 133, 134) of a weft are bonded to each other according to a first predetermined pattern, and yarns (121, 122) of a second warp and the yarns (131, 132, 133, 134) of the weft are bonded to each other according to a second predetermined pattern. The first predetermined pattern and the second predetermined pattern form a textile structure, which includes the yarns (131, 132) of the weft on a first level (L1) and the yarns (133, 134) of the weft on a second level (L2). The yarns of the weft having smaller diameter are configured to alternate with yarns of the weft having a larger diameter on the first level (L1).

Abstract: A method for forming a multi-ply fiber web in which least part of the sizing of the multi-ply fiber web is provided by applying sizing agent in the form of foam by a curtain type application device (C10, C20) in between at least two layers of the multi-ply fiber web in the forming section. The invention also relates to a forming section for a multi-ply fiber web having at least one twin-wire forming part formed between a wire (10) for the bottom layer and a wire (20) for the top layer of the multi-ply fiber web, where the layers are joined, and the treated layers combined. The forming section has a curtain type application device (C10, C20) for applying sizing agent in the form of foam in between two layers of the multi-ply fiber web in the forming section of a multi-ply fiber web production line.

Abstract: A disc chipper has thick double-edged chipper blades clamped in rectangular pockets between a knife segment and a knife clamp which are connected to a chipper disc. The blades are precisely positioned for cutting by knife stops selected from a set of knife stops of incremental modular widths. A different width knife stop is used to position the chipper knife blades each time it is sharpened. After each sharpening the knife blade has a selected width which is smaller by a constant incremental value, and it is assembled with a mating knife stop from the set so that the blade edge position remains unchanged.

Abstract: To minimize the cost of a fiber web due to the web, particularly a board web, being manufactured overly thick to compensate for loss of caliper in the reel-up, the web is made thicker just for the inner layers of what will become a parent roll. The caliper of the web is measured as or after it is unwound. A caliper curve of the parent roll as a function of the diameter of the parent roll is calculated as a function of the diameter of the parent roll and/or the customer roll. The fiber web is adjusted by changing running parameters of the production line: web speed i.e. production speed, headbox-flow, head-box consistency, coating weight of the coating paste or calender nip load.

Abstract: Partial webs are separated in a slitter-winder. The partial webs (WP) are separated by spreading in a spreading device having at least a first, bowed spreader roll (14) fitted at one side of the partial webs (WP) and a second, bowed spreader roll (15) fitted at the opposite side of the partial webs. The partial webs (WP) are guided over the bowed spreader rolls (14, 15) so that the wrap angles (B 14, B15) over the spreader rolls (14, 15) are substantially unequal. The partial webs (WP) are guided to the first spreader roll (14) in a lead-in direction (Dinxy) in the XY-direction and the partial webs are guided from the second spreader roll (15) in a lead-out direction (Doutxy) in the XY-direction such that the lead-in direction (Dinxy) and the lead-out direction are substantially divergent.
