A device for treating a fiber web, especially a device for applying treatment substance for treating a moving fiber web, has at least one nozzle () comprising a channel () for the treatment substance, a frame part (), a tip or end () of the nozzle () and a treatment substance opening () providing a treatment substance spray, which nozzle () has a tip groove area () adjacent to the treatment substance opening (). The nozzle () has at least one opening next to or at the tip groove area () for providing a cleaning fluid flow comprising gas and/or liquid to the tip groove area.

Device for treating a fiber web

A movable support apparatus (), supported on a floor and movable between at least two target stations, for receiving, moving and handing over rolls, winding shafts () and/or machine reels () intended for the handling of a fiber web. The movable support apparatus () has support members () for holding up the load being handled () at both its support ends () and is adapted to be supported on a floor with at least one pressure medium cushion element (). A handling system includes the movable support apparatus (). Rolls, winding shafts () and/or machine reels () may be handled with the movable support apparatus (). The movable support apparatus may be used as a movable winding stand for the winding of a fiber web (W).

Support apparatus, handling system and method

An arrangement for treating a fiber web, in particular for sizing paper and board web (W), using a sizer () which has sizing equipment () located on both sides of the web (W) and size press rolls () located on both sides of the web (W) in between of which a size nip is formed. The web (W) when approaching the sizer () is first guided past the size nip of the sizer () in a process direction (D) and then is turned into an opposite direction (OD) in relation to the process direction (D) by at least one turning guide roll () such that the top side (TS) of the web (W) is sized by sizing equipment () located below the web (W).

Arrangement for treating fiber web

Treatment liquid is sprayed onto a fibrous web surface by one or more spray boxes () having a spray chamber () and spray nozzles () in the travel direction of the fibrous web before a nip (N. . . N; N; N) formed between them by two nip means () provided with a movable surface, and air and/or treatment medium mist is removed from the spray chamber and after having added treatment liquid the fibrous web is pressed in this nip. The spray chamber () is formed between a first spray box () and any successive first nip means () and second nip means (), the fibrous web is guided supported by the surface of the first nip means to the spray chamber and the fibrous web is supported thereon during the spraying of treatment liquid.

Method and apparatus for treating a fibrous web

The present invention relates to a reeling apparatus () for fiber web by which fiber web may be wound to successive reels (). The reeling apparatus has cutting devices () for cutting the web during a reel change, the cutting device being provided with at least one cutting head () disposed movable in a direction essentially transverse to the web direction to cut the web. A contactless web supporting arrangement () is been provided in operational connection with the cutting device to maintain the running of the web stable in a controlled manner during the cutting.

Reeling apparatus for fiber web and method of reeling fiber web

A method and a system to control a reeling profile of a material web reel (), when, in the forming of a material web reel (), a web is reeled around a reeling core and when in an adjustment of CD-directional profiles of the web reel, profiling devices () have been applied. For adjusting quality profiles and reeling profiles of the web, profiling devices are managed with the help of profile measurings of the roller nip and/or of the profile measurings of the reel (), which are obtained from the reel-up (). A measuring device () for a measuring of a CD-directional hardness profile of the fiber web reel includes a measuring head (), which is connected with a loading means (), which loads the measuring head against the fiber web reel. The motion course of the measuring head is linear.

Reeling method and system as well as an measuring apparatus

In a reel change in the reeling process of a fiber material web, the fiber material web (W) running to a reel that is becoming full is changed to run around a new reeling core () brought to a reel change position in such a way that the web is made to adhere onto the surface of the new reeling core (). The web (W) is made to adhere onto the surface of the reeling core () by a change in the properties of the material on the surface of the reeling core (). The material is a combination of an adhesive area () on the surface of the reeling core and a protective layer () on top of the adhesive area, and the properties of the material are changed by removing the protective layer ().

Method for changing a reel in a reeling process of a fiber material web and a reel change apparatus

A method for measuring a nip pressure and/or a pressure profile is provided, wherein a nip-forming roll is fitted with a pressure sensor under a coating layer which is protective and functions as a spring on top of the sensor, and the nip pressure delivers to the bottom surface of the coating a deformation proportional to the nip pressure and the deformation compresses the sensor, which responds to the deformation by generating an electric signal.
