Abstract
Devices and methods for paying off an elongate material between two coaxially aligned packages without interruption. The elongate material from a first wound package is connected to the elongate material of a second wound package by joining the tail end of the first wound package to the head end of the second wound package. Each wound package includes the elongate material having a body portion and a tail portion wound about a core. Also, each body portion has the head end at an outer diameter of the respective package and each tail portion has the tail end at an inner diameter substantially corresponding to a diameter of the core. Further, the path of the wound elongate material is transitioned from the first wound package to the second wound package by providing transition device having a supporting surface.
