This application describes a braided cord containing a braided sheath and optionally a core surrounded by the braided sheath. The braided cord has changing cross-sectional area ranging from 0.0004 mm.sup.2 to 30 mm.sup.2 and contains one or more sections having a tapering angle ranging from 1° to 60° when observed in one direction along the cord axis. The change in the cross-sectional area of the cord can be achieved by changing the thickness of the braided sheath and/or changing the cross-sectional area of the core when the core is present. The thickness of the braided sheath can be adjusted by changing the size and/or twist level of one or more sheath strands, changing the pick count of the braided sheath, and/or using one or more shaped sheath strands. This application also describes a process of producing the braided cord with changing cross-sectional area.

The present invention provides a tapered line production device and method for efficiently producing line of varying thickness. An additional aspect of the present invention is to employ a heat transfer media to provide a tapered fishing line production device and method that operates at high rates of production. Further, the device may be configured to create tapered fishing line with minimal transitional distances between tapered sections.

Braided bodies having a reduced braid density while retaining high tensile properties. High tenacity fibers are braided together at a braid density of less than or equal to 20 picks per inch, wherein the tenacity of the braided body does not decrease with increasing braid density from 17 picks per inch to 19 picks per inch in length of the braided body.

The present invention provides a fishing line comprising a composite yarn having a core-sheath structure, where the composite yarn comprises a core part having a core yarn containing a short fiber and a sheath part having a sheath yarn containing a long fiber; the long fiber in the sheath part and the short fiber in the core part are intertangled with each other; and the core yarn and the sheath yarn are integrated with use of an adhesive resin. The fishing line of the present invention has a robust core-sheath structure which prevents nude yarn or nep from being developed, excellent operability, adjustable specific gravity, excellent tensile strength, high weatherability and water resistance, low water content, low elongation rate, and low probability of unraveling constituent fibers at a cut site.

A leader 10 for fly fishing proposed herein is formed of a single monofilament line. The leader 10 for fly fishing includes a tippet section 11 to which a fly is tied, a butt section 12 to which a fly line is tied, and an intermediate section 13 provided between the tippet section 11 and the butt section 12. Herein, the butt section 12 is thicker than the tippet section 11. The intermediate section 13 includes a front tapered portion 13a having a thickness that gradually increases from the tippet section 11, a rear tapered portion 13b having a thickness that gradually increases from the butt section 12, and a thicker portion than the butt section 12.
