摘要： A roll for a paper machine, in particular for a paper drying device, including an axle on whose support the roll revolves, and a surface construction connected to the axle by support members. The openness of the surface construction of the roll is higher than about 10%, preferably higher than about 20%, so that when the roll an effect is produced that sucks air inward into the roll whereby a flow of air through the roll arises. Also, a single-wire draw dryer group for a paper machine having two contact-drying cylinders and one reversing roll wherein a web to be dried is guided on support of a drying wire meandering from one drying cylinder onto the reversing roll and then onto the other drying cylinder so that on the drying cylinders, the web remains between the cylinder face and the drying wire and on the reversing cylinder, the web is situated at the side of the outside curve. The reversing roll in the dryer group is an open roll having a surface construction with an openness higher than about 10%, preferably higher than about 20%, so that the flow of air traveling along with the wire passes through the open surface construction of the roll into the interior of the roll and is discharged further out along with the wire as an air flow through the open surface construction of the roll.

The group of cylinders are arranged in a row of drying cylinders and a corresponding row of leading rolls or equivalent placed as interlocked with the drying cylinders. The group of cylinders is provided with a single-wire draw so that the heated drying cylinders in the group are placed outside the loop of the drying wire and the leading rolls in the group are placed inside the loop of the drying wire. The stabilization device is arranged in the area between adjacent drying cylinders and the leading roll or equivalent placed as interlocked between the adjacent drying cylinders in the group of cylinders. Air is blow from the device and directed in the direction opposite to the running direction of the paper web. A nozzle opening of the stabilization device is shaped so that the air flow follows a substantially smooth face of the stabilization device while, at the same time, ejecting surrounding air along with it. In preferred embodiments, the smooth face is substantially parallel to the drying wire and the group of cylinders is formed as a compact geometry.

摘要： A method and device for stabilizing the running of a paper web in a paper machine in connection with a paper guide roll, in particular between a press section and a dryer section. In the method, the paper web is passed over the paper guide roll onto a drying wire or equivalent and negative pressure (suction) in the opening nip of the paper guide roll is lowered until a transition is made to the side of positive pressure in order to press the paper web against the drying wire or equivalent. The device includes a nozzle beam and an air chamber which communicates with a blow air duct. The nozzle beam is placed at the side of the opening nip of the paper guide roll such that the blowing discharged out of a nozzle opening of the nozzle beam is directed at the opening nip in order to press the paper web against the drying wire or equivalent.

摘要： Method and device in multi-cylinder dryers of a paper machine, which the dryers comprise two lines of drying cylinders (10,11), in whose connection twin-wire draw is applied, by means of whose drying wire (F1,F2) a closed draw is obtained in the transfer of the paper web (W) from one cylinder line onto the other. In the closed draw, the guide rolls (12/13) of the drying wires (F1/F2) are placed at the proximity of the run of the other wire (F2/F1) on which the drying wire runs from its drying cylinder (11/10) to its guide roll (13/12). For the purpose of ventilation of the pockets (T1,T2) defined by the drying wires (F1,F2) and by the free faces of the drying cylinders (10,11), an air jet or air jets (S1) are blown against the drying wires (F1,F2) within the area in which the drying wire (F1/F2) contacts a portion of the web (W) supported by the other drying wire F2 /F1 which runs over a segment of the circumference of the guide roll (13/12) of the other drying wire F2/F1. From the air jets, drying air is passed through a widening wedge space (N) defined by the said drying wire (F1/F2) and by the portion of the web (W) and the other drying wire F2/F1 which runs over a segment of the circumference of the guide roll (13/12) of the other drying wire F2/F1 into the said pocket (T2/T1) so as to ventilate the pocket. The air jet (S1) or jets are preferably directed perpendicularly to the face of the drying wire (F1/F2) that is opposite relative the web (W) at a location facing the guide roll (13/12) of the other drying wire (F2/F1).

摘要： A single-wire drying group in a paper machine is disclosed including a plurality of drying cylinders whose axes are situated in a substantially common plane, a drying wire carrying a web between successive drying cylinders, one or more deflection rolls, each situated between a pair of successive drying cylinders and wherein the web-carrying drying wire has an incoming run from a drying cylinder to a deflection roll whereupon the drying wire runs over a deflection sector of the deflection roll and then to a subsequent drying cylinder. A blow box has a wall which defines a gap space with the incoming run of the web-carrying wire and a gas flow is directed through the gap space to induce an under pressure on the incoming run to fix the web on the drying wire. The deflection roll has a perforated shell in the perforations of which an underpressure is maintained to ensure that the web remains in contact with the outer surface of the drying wire as the drying wire travels over the deflection or closed sector of the deflection roll.

摘要： A system (20) and associated process for use in the dryer section (18) of a papermachine for promoting complete support of the paper web (32) by the carrier fabric (34) as the fabric and web are transferred between adjacent drying cylinders (22, 24) by way of a turning roll (26) utilizes a blowbox assembly (50) positionable within the pocket region (40) bounded by the drying cylinders and the turning roll. The blowbox assembly is adapted to direct air out of the pocket region to reduce the likelihood of separation of the web from the carrier fabric as the web is moved onto and off of the turning roll. The blowbox assembly cooperates with the vacuum source (30) associated with the turning roll so that upon a reduction of the energy expended by the vacuum source associated with the turning roll, constant sub-atmospheric conditions can be maintained within the pocket region by increasing the expenditure of energy of the air-directing means by an amount which is less than the amount of the reduction of energy expended by the vacuum source.

摘要： A method and device for measuring the permeability of a drying wire to air in which the measurement is carried out continuously while the drying wire moves. The drying wire is guided to run so that it passes over a blow box and a measurement box free of contact, and the pressure in the measurement box and/or the relative change in the pressure is/are measured when the blow box is creating a pressure differential between the blow box and the measurement box in the vicinity of the wire. The pressure and/or the relative change in the pressure is/are compared with earlier measurement results and/or starting values (reference values). The permeability to air of the drying wire is determined on the basis of comparison of the pressure and/or of the relative change in the pressure, and the contact-free measurement is produced by guiding the flow into or out of the measurement box to pass through a gap between the measurement box and the drying wire.

摘要： The invention concerns a method and an apparatus in a paper machine, in particular in its drying section, for intensification of the drying of the paper. In the method the paper web (W) is passed on support of a drying fabric onto a drying cylinder (K). In the method, in connection with the drying cylinder (K), a separate suction device (10) is employed, which is fitted at a distance (F) from the drying fabric, e.g. a wire (H), which follows the face of the drying cylinder. In the method, by means of the suction device (10), the boundary layer (S.sub.1) of moist air, which has been formed on the face of the drying fabric (H), is suctioned off, whereby the drying process is promoted.
