摘要： The invention concerns a method and a device in the dryer section of a paper/board machine. In the dryer section a normal single-wire draw is applied at least partly, in which method the web (W) is passed through the dryer group on support of a drying wire (H). The drying wire (H) presses the web (W) on the drying cylinders (Kn, Kn+1 . . . ) against the heated cylinder faces, and on the reversing cylinders or rolls (Sn, Sn+1 . . . ) between the drying cylinders (10) the web (W) remains at the side of the outside curve. There is one integrated device, through which a support suction and/or blowing is produced in order to improve the runability of the web (W) and to keep the web (W) in contact with the face of the wire, and through which same device, additionally, impingement blowing is produced in order to dry the web (W) and/or to control its tendency of curling.

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： The invention concerns a blow-suction box or equivalent for a paper machine or board machine, which box comprises at least a pressure chamber and which box is placed in the vicinity of a cylinder, roll, or equivalent, from which cylinder, roll or equivalent, a web and/or a wire is/are fitted to run past the box. In connection with the pressure chamber, a nozzle slot has been arranged, out of which a sealing blowing is fitted to be applied towards the cylinder, roll or equivalent and/or towards the web and/or wire running on its face in order to disintegrate the boundary-layer air flow carried along with the web and/or wire. In connection with the nozzle slot, an air guide made of a resilient material has been fitted in order to direct the sealing blowing and to enhance the sealing further.

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.
