摘要： A bark press including a frame and supporting rollers rotatably carried on the frame. These rollers support a rotatable dewatering drum, within which is eccentrically located a press roll, the outside surface of this press roll and the inner surface of the dewatering drum defining a press gap therebetween. The outside surface of the dewatering drum carries at least one ratchet circle with which at least one pressure cylinder cooperates. One end of this pressure cylinder is supported by the frame of the press and the opposite end rotating the dewatering drum step by step through the ratchet circle.

摘要： A method for producing surface-treated paper, in particular of fine paper, and a dry end of a paper machine that makes use of the method. A paper web that has been dewatered by pressing is dried in the forward dryer section, in which drying energy is applied to the paper web over the entire length of the forward dryer section asymmetrically in the z-direction from the side of the bottom face of the web. This step is carried out by a number of successive groups with single-wire draw that are open downward. In this manner, shrinkage of the web both in the machine direction and in the cross direction is reduced or at least partially prevented, which shrinkage tends to take place when the dry solids content becomes higher. Paper broke is removed from underneath the drying groups that are open downward substantially by the force of gravity onto the broke conveyor placed underneath. The paper web which has a tendency of curling because of the asymmetric forward-drying is passed to the finishing section where it is finished while it is moistened and/or worked plastically so that the tendencies of curling that arose in the web in the forward drying stage are substantially reduced.

摘要： A method and device for drying a paper web wherein the paper web is supported on a drying wire without long open draws of the web. The paper web is contact-dried by pressing it with the drying wire onto a face of a contact-drying cylinder whose diameter is greater than about 1.5 m on a sector b whose magnitude is greater than about 180.degree.. The web is evaporation-dried as blowing-on drying and/or as through-drying by means of high-velocity drying-gas jets applied to the web on the drying wire on the face of the following large-diameter cylinder whose diameter is greater than about 2 m on a sector a having a magnitude greater than about 180.degree. while the web is on the side of the outside curve. The web to be dried is passed over a sector c of the suction roll which is subjected to negative pressure while the web is supported on the drying wire at the side of the outside curve. The magnitude of the sector of the suction roll has a magnitude greater than about 160.degree. and the diameter of the suction roll is less than the diameter of the contact-drying cylinder.

摘要： The present invention concerns a feed and accept duct system (4) for hydrocyclones (1), comprising common feed and accept ducts (7,8) which have by connecting tubes been connected to the parallel hydrocyclones. This type of construction is used, for instance, in purifying fiber suspensions, in which process the suspension is fed into the hydrocyclones (1) and the purified suspension is removed therefrom as a so-called accept fraction into the accept duct (8). It is essential in the invention that the connecting tubes of the feed and accept ducts (7,8) have been so placed on the different hydrocyclones (1) that the tubes are located substantially in parallel, that the feed and accept ducts have been formed inside a common shell (5) by dividing the space confined by it into two parallel ducts by means of a zigzag partition (6), and that the ends of the connecting tubes (11,12) are located at the folds formed by the bights of the partition, the partition confining the feed duct connecting tubes to be on the feed duct side and the accept duct connecting tubes to be on the accept duct side.

摘要： A dryer section of a paper machine including groups with single-wire draw that include a drying wire guided in a loop and reversing cylinders arranged in the drying-wire loop. Contact drying cylinders are arranged in gaps between the reversing cylinder and the drying wire is guided to press a web against heated faces of the contact drying cylinders. In addition to normal, small-diameter contact drying cylinders, one or more large-diameter contact drying cylinders (the diameter being greater than about 2200 mm and usually in a range from 2200 mm to 3600 mm), is/are used in one or more single-wire draw groups. An impingement-drying/ventilation hood is arranged above the large-diameter contact drying cylinders and extends on a large sector above the contact drying cylinder and above the drying wire and the web running over the cylinder. An impingement-drying/ventilation effect is applied to the drying wire through the impingement-drying/ventilation hoods on the large sector. By means of the effect, a moist boundary layer in contact with the drying wire is disintegrated and drying is promoted from a side of a face of the web opposite to the web face that is placed against the contact drying cylinders.

摘要： A method and device for enhancing the run of a web in a paper machine in which water is removed from the web by pressing the web in at least one press nip and after pressing, the web is dried in at least one dryer group applying impingement drying. The web is guided along a substantially linear path or by using a large curve radius in the dryer group applying impingement drying. In the drying stage, after the impingement drying, the web is dried in at least one dryer group having normal single-wire draw. The web is passed from the pressing stage to the drying stage as a closed draw and more particularly, from the pressing stage to the area with single-wire draw in the drying stage so that the web is constantly supported against at least one support face.

摘要： A device for threading a paper web from a dryer section to a finishing device situated after the dryer section in the running direction of the web including a rope threading arrangement. A leader strip is separated from the edge of the paper web in the dryer section and the leader strip is directed between a pair of ropes included in the rope threading arrangement. The leader strip is carried to the finishing device on support of the ropes. To effect the transfer of the leader strip from the drying wire to the rope, at the inlet side of the last drying cylinder in the dryer section, a rope gap is formed out of the ropes and the leader strip, which is supported by the drying wire thereat, is transferred by an air blowing into the rope gap. The leader strip is passed by the ropes over the last drying cylinder to the finishing device.

摘要： A group with single-wire draw in a dryer section of a paper machine having heated smooth-faced drying cylinders against whose smooth face a paper web to be dried is brought into direct contact, and reversing cylinders. The group with single-wire draw also includes a drying wire which is guided in a loop by guide rolls as well as by the drying cylinders and reversing cylinders so that the drying cylinders are placed outside the wire loop and the reversing cylinders are situated in gaps between the drying cylinders inside the loop of the drying wire. In the group with single-wire draw, the drying cylinders include large cylinders and small cylinders, the diameter of the large cylinders is substantially larger than the diameter of the small cylinders. The small cylinders are placed in gaps between the large cylinders so that their centers of rotation are on a level substantially different than the level of the centers of rotation of the large cylinders. The reversing cylinders are arranged on the runs of the drying wire and the web from a large cylinder to a small cylinder and from a small cylinder to a large cylinder, the centers of the reversing cylinders being placed on a level substantially different than the corresponding levels of the large cylinders and the small cylinders.
