A method and an apparatus for controlling the cross-directional nip profile of a reeling nip in a reeler, in which the reeling nip is arranged by means of a reeling core or a growing machine reel and at least one loop of an endless supporting member continuous in the direction of the axis of the reeling core. To control the cross-directional nip profile of the reeling nip, variables proportional to the tension of the supporting member are measured, cross-directional tension profile of the supporting member is determined on the basis of said variables, and further, a cross-directional nip profile of the reeling nip is determined, said nip profile being controlled by adjusting the determined cross-directional tension profile of the supporting member.

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.

A beam structure for a web forming machine is arranged to be supported by its end components () on the web forming machine. The beam structure includes a casing structure () of a thin-sheet material, inside which a stiffener structure () is arranged. In addition, the casing structure () and the stiffener structure () are secured to each other to create a load-bearing beam structure.

A backing lath ( ) used for coating a web of paper or paperboard in doctor blade and rod coaters and film-transfer coaters, the backing lath featuring a fiber-reinforced composite material body. When necessary, the backing lath can be surfaced with a wear-resistant coating. The invention also concerns a doctor element assembly, wherein the backing lath has a fiber-reinforced composite material body.
