ABSTRACT:
A method and device for reeling a paper or board web, wherein a first reel spool is in a reeling position in nip-defining relationship with a reeling cylinder and an empty second reel spool is placed in a stand-by position, the web is carried on a belt until it is reeled onto the first reel spool and the belt is guided in a run over the reeling cylinder and a guide roll, the first reel spool being transferred from the reeling position and pushed by the guide roll to a change position and the second reel spool is moved to the reeling position when the reel formed on the first reel spool is complete. The reeling of the web is transferred from the reel formed on the first reel spool to the second reel spool by cutting the entire width of the web by initially cutting a middle region of the web to form a tip and then extending the tip to side edges of the web, blowing the tip onto the second reel spool when the second reel spool is in the reeling position, and applying an adhesive proximate a rear edge of the web reeling onto the first reel spool in advance of a cut line separating the web reeling onto the first reel spool and the tip simultaneous with the cutting of the entire width of the web. The adhesive is applied at a uniform distance from the cut line so as to glue and fix the rear edge of the web to an underlying web portion of the web reeling onto the first reel spool.
