ABSTRACT:
A coupling structure capable of coupling films to a leader with high reliability. The leader has a leader body formed with first holes and second holes in its rear with respect to the feed direction of the leader. Sheet members having fingers or protrusions are provided on the leader body so that the fingers extend across the respective first holes. Films having holes formed in its leading end, are coupled to the leader body by inserting their leading ends through second holes and then into the first holes until the fingers engage in the holes formed in the films.
