Apparatuses and methods are provided for cutting a traveling web of paper that is being spooled on a full spool and transferring the paper web to spool on an empty spool by driving turn-up tape into a nip between the empty spool and the paper web. The apparatuses and methods provide a more problem free way of transferring a traveling paper web to an empty spool. The apparatuses include a drive and a transfer track for transporting the tape beneath the paper web and delivering the tape into the nip, the transfer track including, a horizontal section having a front end and a back end and a first groove running the length of the horizontal section, the first groove being defined by a first top wall, a first side wall, a first bottom wall, and a first flexible seal such that the turn-up tape travels substantially vertical in the direction of travel underneath the paper web, and a turn-up section connected to the back end of the horizontal section, the turn-up section being curved upwardly from the horizontal section to a position adjacent to the empty spool, and the turn-up section having a second groove running the length of the turn-up section, the second groove being defined by a second top wall, a second side wall, a second bottom wall, and a second flexible seal, the turn-up tape traveling substantially perpendicular to the second bottom wall, whereby the drive is capable of driving the turn-up tape to the end of the transfer track. The methods including rotating an equal angle cam in contact with the turn-up tape to move the tape down the transfer track and into the nip.
