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.

Method and an apparatus for controlling a nip profile of a reeling nip

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 ().
