摘要:
The invention provides a convenient, lightweight and streamlined connecting device for attaching a leader or tippet to a fly-fishing line. The Fly Line Connecting Device is configured with an expandable tubular lattice that allows for an in-line connection to the fly line. The connection device has an integral tubular lattice sized with an internal diameter that is slightly smaller that the fly line and when compressively displaced, operates to expand the internal diameter to allow insertion of the fly line. Once the fly line is fully inserted, the tubular lattice is allowed to contract and elastically constrict onto and thereby grip the semi-resilient surface of the fly line. When the fly line and leader line are placed in tension through the connecting device, the tubular lattice acts to constrict down on the fly-line to resist separation. The connecting device of the invention is configured with a loop, eyelet, knot-trapping feature, or short tippet to allow for the convenient attachment of the leader line. Alternatively, the connecting device is permanently attached or integrally formed with a full-length leader. The preferred embodiment of the connecting device is injection molded in an intermediate form that is configured to be manually or machine cold-drawn to the final working dimensions and optimal physical properties.
摘要:
Composite flylines made with a core line, a polymeric coating over the core line for adjusting the line profile and density, and a braided layer over the polymeric coating. The braided layer provides strength without sacrifice in flexibility and provides a more cost efficient manufacturing process through the reduction or elimination of production scrap. An optional outer coating can be applied to further reduce surface friction, increase abrasion resistance, or provide coloring.
摘要:
An implantable porous expanded polytetrafluoroethylene material having a microstructure of nodes interconnected by fibrils wherein a surface of the material has been modified by the removal of fibrils from the surface so that under magnification the surface has the appearance of freestanding node portions not interconnected by fibrils but rather having open valleys disposed between the freestanding node portions. Unmodified material beneath the surface maintains the original microstructure of nodes interconnected by fibrils. The modification is preferably done by exposing the surface to radio frequency gas plasma discharge with a reactive etching gas for a lengthy amount of time such as about ten minutes. The depth of fibril removal from the surface is substantially a function of the duration and amount of energy applied to the surface.

The invention relates to a tactile indicator on a fly casting line to indicate to a fisherman before the initial cast or when the line is being retrieved that the desired casting length of line is extended beyond the tip of the fly rod and that the rod and line are ready for casting.

The disclosure is a fly fishing training line wherein the training line is attached to a traditional fly fishing rod housing a fly fishing line. The training line is comprised of a heavier line material than the fly fishing line per meter and is end-weighted having two types, a first and second type of cord, wherein the second type is heavier than the first type and a short segment of the second type is fitted between two segments of the first type of cord nearer the fly end of the line.

The present disclosure is to a fly fishing line and a method of making a fly fishing line. The method includes preparing a composition comprising a polymer resin, a co-polymer of silicone, and one or more other polymeric materials. The method includes applying the composition around an elongated core. The method also includes exposing the composition to conditions that form a coating around the elongated core thereby forming the fly-fishing line. The composition is a plastisol composition and the polymer resin is a polyvinyl chloride resin. The fly fishing lines include an elongated core a coating disposed around the elongated core. The coating comprises a polymer resin, a co-polymer of silicone, and one or more other polymeric materials.
摘要:
Porous expanded polytetrafluoroethylene material having a microstructure of nodes interconnected by fibrils wherein a surface of the material has been modified to have increased hydrophobicity as indicated by having a water droplet roll-off angle of less than about 10 degrees in comparison to a typical roll-off angle of greater than about 12 degrees for the unmodified material. Under magnification, the surface morphology may be indistinguishable from that of the unmodified precursor material. The modification is preferably done by exposing the surface to radio frequency gas plasma discharge with a reactive etching gas for a lengthy amount of time such as about ten minutes. If surface etching is continued beyond a time adequate to produce the highly hydrophobic behavior, then the surface morphology includes the appearance of broken fibrils. Still further treatment results in complete removal of fibrils from the surface so that under magnification the surface has the appearance of freestanding node portions not interconnected by fibrils but rather having open valleys disposed between the freestanding node portions.
摘要:
A line for fly casting is disclosed having a forward continuous taper from a widest point adjacent the center of the line, more or less, down to a minimum at the forward end of the line where a leader and fly are to be located. A reverse taper joins the forward continuous taper. The remainder of the line is a relative small, constant diameter and attaches to a reel.
