摘要： In the method in unwinding, paper web (W) is discharged from a reel (R1) that is becoming empty and the paper web of a new full reel (R2) is spliced at the discharge speed to the paper web discharged from the reel that is becoming empty. The terminal end point (L) of the web of the reel (R1) that is becoming empty is stored as information indicating its position in the longitudinal direction of the web in a readable memory (M) corresponding to the reel. During the discharge the distance travelled by the web is determined and compared to the memory, and when there is a predetermined length of web to the terminal end point (L) remaining on the reel (R1) that is becoming empty, a splicing command is given, whereafter the leading end of the paper web of a new full reel (R2) is spliced to the paper web (W) being discharged.

摘要： A paper web is continuously reeled into reels around rotating reeling cores. Before a change of reel a new empty reeling core (5) is brought to the change station into change connection with the paper web (W) going to the old reel (R), and when the old reel (R) is full, the web is changed in a change event to travel to the periphery of the new reeling core (5) and a primary reeling is started where the web is guided to form a rell around the reeling core (5) through a reeling nip (N1) between the loop of an endless supporting member (1) and the reeling core. From the primary reeling a change is made to secondary reeling, where a portion of the supporting member (1) carrying the web brings the web to the reel, and the web moves over to the reel in a reeling nip (N) between said portion and the outer periphery of the reel. During the secondary reeling at least in some stage the reeling core (5) is transferred in relation to the loop of the supporting member (1) according to the increase of the diameter of the reel (R) in such a manner that the position of said reeling nip (N) moves forward on the web-carrying portion of the endless supporting member (1) in the travel direction of said portion. A first guide roll (2) of the web-carrying portion of the loop of the endless supporting member (1) is transferred in the direction of the periphery of the reeling core (5) so that the distance of the reeling nip (N1) located between the reeling core (5) and the loop of the supporting member (1) from the first guide roll (2) changes in the primary reeling.

摘要： The invention relates to a method and an apparatus in reeling up, in which a paper web or the like (W) is reeled around a center-driven reel spool (5), which is transferred from the primary reeling to the secondary reeling, in which reeling the reel spool (5) is transferred in accordance with the growth of the reel by means of a transfer device (7) at least at some stage of the reeling and the web is brought at said stage from below the reel spool (5) via a reeling nip (N1) formed by the reel spool (5) and a loop (1) of an endless supporting member. According to the invention the web (W) is guided around the reel spool (5) during the reeling via an auxiliary nip (N2) formed by means of the reel spool (5) and the roll (10, 10’).
