Abstract
A breakdown spool is provided having a barrel and at least one flange formed separate from the barrel. The barrel has an insertion end that includes an annular ring spaced from the axial end and projected radially from the barrel winding surface. The flange includes a receiving channel for receiving the insertion end of the barrel to form the completed spool. The receiving channel includes a first portion for receipt of the end of the barrel and a second portion for receiving the annular ring. The second portion is recessed within the support surface such that the annular ring aligns with the support surface on the flange. A locking mechanism is provided for axially securing the insertion section of the barrel within the receiving channel of the flange.
