    摘要: A method and device for contact-free treatment of a web in which the web is treated, for example supported, reversed, spread, carried, and/or dried, by blowings which provide a carrier-face zone. The carrier-face zone has a curved form regulatable in a direction transverse to the direction of progress of the web. The nozzle-carrier face unit of the device is bent to the curved form in the cross direction of the machine while a frame part of the device is kept in a stationary position. The device includes a regulation arrangement for bending the nozzle-carrier-face unit to a curve form in the direction transverse to the running direction of the web while the frame part of the device is supported in a stationary position.

    摘要: A nozzle arrangement in an airborne web-drying apparatus for drying a coated paper web (10) or the like. The nozzle arrangement comprises at least one overpressure nozzle (14), which is arranged to blow drying air both in the web's travel direction and against the web's travel direction. The nozzle arrangement comprises further a direct impingement nozzle (16) combined with the exit side and/or the entrance side (26) of the overpressure nozzle, in which direct impingement nozzle a plurality of nozzle slots or nozzle orifices (17) are formed in order to blow drying air mainly perpendicularly toward the web. The perpendicular distance (a1) from the nozzle surface (30) of the direct impingement nozzle (16) to the web is larger than the perpendicular distance (a2) from the supporting surface (32) of the overpressure nozzle (14) to the web.

    摘要: A method and flotation dryer unit effects drying of a web such as a coated paper web. The flotation dryer unit advantageously includes several nozzle boxes extending across the web for feeding drying air toward the web to be dried, a distribution chamber for drying air for leading the dry air into the nozzle boxes, and a suction chamber for gathering the drying air led toward the web from the web area and for directing it to the side of the web. The suction chamber is divided into an equalizing space and an air transport chamber by a perforated plate for equalizing the return air flow occurring from the web area.

    摘要: A method and a device for stabilizing the web run in a paper machine or the like having a blow suction module (12) mounted above and/or below the web. The blow suction module comprises a blow nozzle unit (14) extending across the web, through which gas, such as air or combustion gas, is blown against the web (10) from the blow nozzle unit, and a first air discharge unit (18) arranged on the front side of the blow nozzle unit, and a second air discharge unit (22) arranged on the back side of the blow nozzle unit, which remove air or gas from between the web and the blow suction module. The blow suction module is asymmetric regarding the first and second air discharge units, so that more air or gas is discharged via the first air discharge unit than via the second air discharge unit.
