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 in a paper machine for transferring a paper web from a wet wire in a former section to a pick-up fabric or an equivalent transfer fabric of a press section, including the steps of forming a pick-up point on the wet wire and separating an edge strip from at least one edge of the web prior to the pick-up point by means of at least one cutting device. The method further includes separating the web from the wet wire and passing the web onto the pick-up fabric at the pick-up point. The method also includes applying a pressure difference to the at least one edge strip through the wet wire or the pick-up fabric at or after the pick-up point to cause the at least one edge strip to either follow the wet wire or become separated from the pick-up fabric after the pick-up point and to be placed in a broke system arranged beneath the paper machine.

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.

摘要： A sample collecting device takes samples from the white water drained from the web through the wire in the wire part, at a number of points in the cross direction of the web. An analyzer analyses the samples and forms a retention profile for controlling the paper machine. The device for measurement and regulation of the retention profile comprises means for measurement of the retention profile across the web width from different points of width of the web. The headbox comprises ducts passing to different points of width of the headbox to pass a flow of liquid containing a retention agent in the headbox into connection with the stock flow to regulate the retention profile across the web width. The ducts have valves which are regulated on the basis of the retention profile data for regulating the retention agent into duct flow.

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 two part first dewatering zone (Z1), the first part formed by a suction forming roll engaging a forming wire (12) and the second part formed by a fixed forming shoe engaging opposite a forming wire (11). The wires (11, 12) are guided so the first dewatering zone causes essentially non-pulsating dewatering in the stock. 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).

摘要： A 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. A method in a suction box in a paper machine, wherein a vacuum is formed in a vacuum chamber of the suction box and, during formation of the vacuum, the deck and/or the ribs is/are pressed against the wire. At least in a running situation, the curve form of the deck of the suction box or the position of the ribs is such that the tension of the wire running over the deck or ribs lowers the normal force which is produced by the vacuum present in the suction box and which is effective between the wire and the deck/ribs.
