Abstract
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).
