    摘要: In the method for threading of a paper or paperboard web a narrower tail (T) separated from the paper or paperboard web (W) is conveyed between different holding points. On the travel path of the tail (T) there is at least one tension measuring device (1) which is arranged to measure the tension of the tail (T) passing by, said device (1) being connected to a data processing unit (7) which is connected to tension control means affecting the tail (T). The threading can be conducted on a tension level lower than the actual running tension of the full-width web (W).

    摘要: A method and apparatus for reeling or winding of a web in which one or more factors affecting the web in the reeling or winding process are controlled by means of measurement data in order to affect the quality of the reel or roll formed in the reeling or winding process. The is measurement data used is the web tension profile of the web brought into the reeling. The web tension profile is measured by means of a measuring device from which the web tension profile data is transmitted to a data processing unit which adjusts the factors affecting the web during reeling or winding.
