摘要： A multi-layer web formation section has two successive wire units (300, 310) with a common wire (11). A first headbox (100) supplies fiber pulp to the first wire unit (300) forming a first partial web (W1). A second headbox (110) supplies a new fiber pulp layer to the forward end of the second wire unit (310) atop the first partial web. A first non-pulsating dewatering zone (Z1b) in the forward end of a two-wire stretch of the second wire unit (310) has a first formation shoe (200b) with a curved cap (201) placed on the side of the new layer having openings (202) extending through the cap (201) with an under-pressure (P) affecting therethrough. A two-wire stretch of the second wire unit (310) has a second pulsating dewatering zone (Z2b) formed by fixed dewatering lists (210b), between which there are gaps (220b) and an under-pressure (Pb) affecting in these.

摘要： A multi-layer web formation section has at least two successive wire units (300, 310). First and second headboxes (100, 110) supply pulp suspension jets to the forward end of the first wire unit (300) and the second wire unit respectively to form a first partial web (W1) and a second partial web (W2) which are joined at a joint (N1) between the second wire unit (310) and a bottom wire (11). A first non-pulsating dewatering zone (Z1b) in the forward end of a two-wire stretch of the second wire unit (310) is formed by a fixed formation shoe (200b) having a curved cap (201) placed against one side, having openings with an under-pressure applied. A two-wire stretch of the second wire unit (310) has a second pulsating dewatering zone (Z2b), formed by fixed dewatering lists (210b) in the cross machine direction with gaps (220b) therebetween with an under-pressure (Pb) applied.

摘要： A forming section has a lower wire loop (11), which constitutes a single-wire section (T) following a breast roll (12). A first dewatering zone (Z1) has at least one stationary, first forming shoe (40) followed by a pulsating strip cover (50). The first forming shoe has leading and trailing edges and underpressure affecting through holes of the cover. The holes are openings or slots substantially in the longitudinal direction of the machine, whereby non-pulsating dewatering is applied on the stock travelling on top of the lower wire. A pulp suspension jet is fed from a headbox (30) at an impact point after the shoe leading edge. The cover is straight at least in the area between the impact point of the pulp suspension jet and the trailing edge. The impact of the pulp suspension jet on the forming wire is thus better controlled in a better way, increasing production speed.

摘要： At the end of the twin wire zone of a paper machine former, a suction box (17) inside the upper wire loop (11) has a curved lid (17′) opposite a roll (18) within the lower wire loop (10). The lid is curved in a run situation so the tension of the upper wire (11) reduces the normal force between the wire (11) and the lid (17′) caused by the underpressure of the suction box. The underpressure keeps the web mainly off from the roll (18) and the lower wire (10) while being adhered to the underside of the upper wire (11) and conforming to the curved shape of the lids. Members (17a, 18′) are provided for making the web follow the lower wire (10) in a break situation for conducting it to the broke handling system.

摘要： A method, device, and arrangement in a paper machine for regulating the control of the transverse profile or profiles of properties of a paper web produced therein. Water is removed from the paper web under compression between two forming wires by making use of dewatering and/or forming ribs. The deflection of the dewatering and/or forming ribs in the transverse direction of the web is regulated thereby affecting the retention profile of the paper web in the cross direction. By regulating the deflection of the dewatering and/or forming ribs, the transverse fiber-orientation profile and/or the filler profile of the paper web is influenced through the control of the transverse retention profile of the web.

摘要： A forming section of a paper or board machine 10 in the forming section of a paper or board machine has a cover 36 having an outlet groove 20 between a suction zone 18 of circular holes and an outlet edge 40. A wire comes to the cover area from an inlet edge 38 and leaves from an outlet edge 40. The outlet groove 20 is essentially in the cross-machine direction of the cover 36. The suction zone accomplishes non-pulsating dewatering, and the outlet groove accomplishes pulsating dewatering. The non-pulsating suction zone first accomplishes good retention, and after this formation is improved on the outlet groove. When pulsating dewatering takes place in the same direction as non-pulsating dewatering and immediately after non-pulsating dewatering, the web formed has a particularly good formation potential. Potential marking caused by non-pulsating dewatering can also be removed efficiently by means of pulsating dewatering taking place on the same side.

摘要： Suction box in a paper machine including a vacuum chamber, a deck or a number of substantially U-section holders open toward a wire and ribs arranged in the deck or the holders so that they can be loaded against the wire. At least in a running situation, the deck of the suction box is curved or the ribs are arranged to provide a curve run of the wire so that the wire tension of the curved run over the deck or ribs serves to lower a normal force which is produced by the vacuum present in the suction box and which is effective between the wire and the deck or ribs.

摘要： Fibrous stock is supplied by a paper or board machine headbox (1) between looped forming wires (11, 12). Water is removed in a first dewatering zone (Z1) formed with a fixed forming shoe (3) having a curved surface against which a wire (12) is supported while the opposite wire (11) is unsupported in the area of the shoe (3). Water is removed in a second dewatering zone (Z2) formed by fixed dewatering blades (21) on the other side of the wires (11, 12) and supported against the stock therebetween (21) and on the opposite side of the wires (11, 12) by dewatering blades (24), loaded in a controlled manner against the fixed dewatering blades (21) at gaps (22) between these so that pulsating dewatering is caused in the second zone (Z2). The wires (11, 12) are guided so the shoe (3) causes essentially non-pulsating dewatering in the stock.
