METHOD AND DEVICE IN A CHANGE IN REELING UP OF A PAPER WEB

摘要

The invention relates to a method in a change conducted in the reeling up of a paper web, in which a continuous paper web (W) which is passed from a paper machine and/or finishing treatment of paper and whose width corresponds substantially to the width of production is guided via a member (11) functioning in a nip-like manner to form a machine reel (13) around a center drive assisted reeling core (12), and in which method the machine reel (13) that is becoming full and said member (11) functioning in a nip-like manner are separated from each other, in other words the nip contact is disengaged and reeling up to said machine reel (13) continues until the paper web (W) is cut, and after the cutting the reeling up continues immediately to an empty reeling core (21) brought in connection with the member (11) functioning in a nip-like manner. According to the invention, a tension measurement member (TM2) is placed in the free section of the paper web (W) between the member (11) functioning in a nip-like manner and said machine reel (13) that is becoming full, and the tension measurement information (M) given by said tension measurement member is used by a control system (CS) for example to control the center drive affecting the center of the machine reel (13). The present invention also relates to a tension measurement device implementing the method.
