A method and device for reeling a paper or board web in a drum reel-up or equivalent, in which, when a paper or board reel formed on a reel spool situated in a reeling position becomes complete, a new reel spool is brought by transfer members into a stand-by position and accelerated up to the web speed. The reel spool with the complete reel is transferred into an exchange position apart from the reel drum and the new, initially accelerated reel spool is transferred into the reeling position. When the reel spool with its reel is transferred into the exchange position apart from the reel drum, the belt guide roll is transferred into nip-defining relationship with the complete reel that is being formed onto the reel spool and is displaced along with the reel spool into the exchange position so that the web runs during the entire exchange on support of the belt and through a nip between the guide roll and the reel spool. The device includes a reel drum, a reel spool whereby the web runs through the nip between the reel drum and the reel spool onto the reel spool, a transfer device for bringing a new reel spool into nip-defining relationship with the reel drum after the paper or board reel on the first reel spool has become complete, and means for transferring the belt guide roll together with the reel spool into the exchange position so that, during the entire exchange, the web is supported on the belt and runs through the nip between the guide roll and the reel spool.
Method for reeling a web in a drum reel-up, wherein a first reel spool is in a reeling position in nip-defining relationship with a reel drum and an empty second reel spool is placed in a stand-by position and accelerated up to web speed when the reel of the web formed on the first reel spool is complete, comprising the steps of:
A device for reeling a web in a drum reel-up including a reel drum and a first reel spool in nip-defining relationship with said reel drum when the web is reeled through the nip and onto said first reel spool, and a transfer device for moving an empty second reel spool into nip-defining relationship with said reel drum after the reel on said first reel spool is complete, comprising
