The invention relates to a method and an unwinding section for unwinding a fiber web from a parent roll, which unwinding section comprises at least one unwinder for unwinding a fiber web from a parent roll and a joining device configured to join a trailing end of a running-out parent roll to a beginning end of a next, new parent roll to be unwound in a parent roll change. The unwinding section comprises a broke handling device configured to handle broke. The unwinding section comprises a tensioning device located between the joining and the broke handling, and the tensioning device is configured to tension and straighten the fiber web to be joined between the tensioning device and the joining device before joining of the end of the fiber web from the running-out parent roll and the end of the fiber web from the next parent roll to be unwound.
Unwinding section for unwinding a fiber web from a parent roll, which unwinding section comprises at least one unwinder for unwinding a fiber web from a parent roll and a joining device configured to join a trailing end of a running-out parent roll to a beginning end of a next, new parent roll to be unwound in a parent roll change, and which unwinding section comprising a broke handling device configured to handle broke, which unwinding section further comprises a tensioning device configured to tension and straighten the fiber web to be joined between the tensioning device and the joining device before joining of the end of the fiber web from the running-out parent roll and the end of the fiber web from the next parent roll to be unwound, the tensioning device being located between the joining and the broke handling the tensioning device being configured to guide the cut beginning end of the fiber web from the next parent roll to be unwound after the joining of the ends of the fiber webs in the parent roll change to the broke handling device.
Method for joining ends of fiber webs in a parent roll change of an unwinding section located in vicinity of or comprising a broke handling device configured to handle broke, in which method the ends of the fiber webs are configured to be joined by a joining device, in which method the fiber web running from a next parent roll to be unwound is tensioned and straightened by a tensioning device before joining of the end of the fiber web from the running-out parent roll and the end of the fiber web from the next parent roll to be unwound, the tensioning device being located between the joining and the broke handling, the cut beginning end of the fiber web from the next parent roll to be unwound after the joining of the ends of the fiber webs in the parent roll change being guided to the broke handling device.
