摘要： The invention relates to a method in a continuously operating unwind for a fibre web, in particular for a paper or board web, in which unwind a machine reel is unwound in a primary station and in a secondary station, and in which a new machine reel (13) brought to the unwind is joined at full speed to a web (W) of an emptying machine reel (10) by means of a splice roll (12) of a splicing device. In the method the old machine reel (10) and the new machine reel (13) are moved substantially horizontally. In the method the new machine reel (13) and the old machine reel (10) are moved by means of two pairs of linearly movable carriages such that the unwinding starts on a pair of carriages that has a primary brake gen¬ erator for control of web tension, acceleration of the new machine reel (13) to unwind speed being carried out while the carriage moves towards the primary winding station. The invention also relates to a continuously operating unwind for a fibre web, in particular for a paper or board web, for carrying out the method. The unwind comprises a primary station and a secondary station as well as a splicing device comprising a splice roll (12) and a web guide roll (11), which unwind comprises means for moving an emptying machine reel (10) and a new machine reel (13) substantially horizontally. The unwind further comprises two pairs of linearly movable carriages and that both pairs of carriages comprise a brake generator.
