A left-handed twist; a twist that would be laid out by turning the yarn or rope in a counterclockwise direction.
A number that the tensile strength is divided by in order to determine the safe working load (for new rope in good condition with proper splices).
A cord used within the frame of certain windows that works on a pulley to help raise and lower the window easily within its frame. It is generally a solid braid cotton with various fiber cores for low stretch; a sash cord may also be used for other utility purposes.
Cone shaped, made of canvas, open at one end or both ends. Equipped with a tow-line at the large end and a tripping line at the other. Designed to keep the bow of the life raft heading into the seas.
A small diameter twine either braided or twisted most commonly of nylon; used in making fish nets, net repairs, fishing line, chalk line, duck decoy, anchor lines and many other utility uses.
To lash or bind ropes together.
To close or tighten a knot.
A small U-shaped fitting often used to join the thimble in an eye splice to the fitting. The open end is connected by a screw pin. (A snap shackle has a spring loaded pin.)
A grooved wheel or roller in a block or pulley over which the rope passes.
Method for joining rope, end to end, when maximum strength is desired when an increase in diameter is acceptable and/or when only a small amount of rope can be spared for making a splice.
An elastic cord used for tie down purposes, snubbing gear, etc. Made of elastic rubber core with a braided synthetic fiber jacket.
S.I.M.A. Extrusion Technology:
The most advanced technological solution in the field of fibrillated and non-fibrillated PP and HDPE tapes production, designed for the fabrication of twisted rope, fishing nets, insulated cables, baler twine, binder twine and other industrial applications.
The fiber of the Agave Sisalana used for making cordage and rope. May also refer to the Henequin or Agave Fourcroydes, a plant native to Yucatan, Mexico.
A continuous length of yarn or cord of any desired length, in the form of a collapsible coil.
Ski Tow Rope – For Water; Usually a small diameter hollow braid polypropylene rope used for pulling water skiers behind motor boats. For Snow; Usually a three strand twisted rope of various synthetic fibers attached to a motor, this rope pulls skiers uphill.
To use a loop (bight) of rope instead of the end when closing a knot to make untying the knot easy.
A continuous strand of parallel overlapping natural fibers (manila, cotton, sisal, jute, etc.) ready for twisting.
A single sheave block with a hinged strap that can be opened and the bight of a line inserted.
A construction of 9, 12 or 18 strands of fiber, lock-stitched together. It has a smooth, round, firm contour which holds its shape well under pressure and load. It is excellent in pulleys and winches and whenever a firm round rope is needed. It is not as strong as other braids nor is it as spliceable.
In general, any mast, yard, pole or boom.
– Ratio of the mass of a material to the mass of an equal volume of water.
A light, very large three cornered sail set flying forward of all fore stays. Used on racing yachts when running the wind.
The joining of two ends of yarn, strand or cordage by intertwining or inserting these ends into the body of the product. An eye splice may be formed by using a similar process to join one end into the body of the product.
A rope in which each strand consists partly if wire and partly of fiber. It is composed of six main strands laid around a fiber core. It will show fish hooks after it has been stressed.
A fiber that has been texturized by spinning before it is twisted into yarn, giving it a woolly texture, similar to cotton. It is common in nylon, polyester and Dacron™.
The main part of the rope not in the knot itself, the rope not being tied is the standing part.
Standing Rigging – Rigging holding up the masts that is usually not adjusted while sailing.
A strong abrasion resistant braided cord usually of nylon; used for hand-wound gasoline engine starters and other utility purposes.
Runs through the stern chock to control forward movement and assists the breast lines. Aft Spring.
Used to stop the rope from pulling through a cleat, hole or pulley.
The largest individual element used in the final rope-making process and obtained by joining and twisting (or braiding) together several yarns or groups of yarns.
Natural fibers of cut lengths from filaments of man-made fibers. The staple length of natural fibers varies from less than 1″ for some cotton fibers to several feet for some hard fibers. Man-made fibers are cut to a definite length, usually about 1-1/2″ but occasionally down to 1″, so they can be processed on the cotton, woolen and worsted systems. The term staple (fiber) is used in the textile industry to distinguish natural or cut length man-made fibers from filament.
A line used for extending a wire or cable
Any non-organic fiber used in rope or cordage manufacture.
