ABSTRACT:
Thread is wound between spin hooks (20) and anchor hooks (26) and around loop-pins (TP, BP) to form two thread groups, one extending between a first spin hook (20) and the anchor hook (26) and the other extending between the anchor hook (26) and the second spin hook (20). The spin hooks (20) are both rotated in the same direction, at the same speed, for separately twisting the two thread groups. Then, the two separately wound thread groups are moved laterally together and allowed to unwind and at the same time wind together in the opposite direction, to form a single fly fishing leader, or the like. The thread is wound to form twelve thread strands in a butt section of the leader, ten thread strands in a mid-section of the leader and eight thread strands in a tip section of the leader (FIG. 11). As a result, the leader that is formed tapers from the butt end to the tip end.
