HISTORY MARITIME REPORTER’S 70TH ANNIVERSARY EDITION
The history of rope making is as longas that of the human race. Archeologiststell us it was one of the first tools creat-ed from various grasses, reeds, and ani-mal sinew. These rudimentary ropeswere used for fishing, hunting, shelterbuilding, agriculture, and the domesti-cation of animals. For millennia, thosewho used rope were the ones who madeit. The mechanization of the rope-mak-ing process did not begin until the num-ber of sailing ships grew to the pointthat the demand for ropes outstrippedsupply. Among many cordage compa-nies to answer the demand for rope, afew stand out as influential and innova-tive in the industry.
As the machinery was developed,companies were founded that wouldinfluence the cordage industry well intothe 21st century. In 1816, GladdingBraided Products was founded to supplyrope to the clipper ship market, andlater, in 1869, Hooven Allison appearedon the scene, having pioneered the ropeindustry during the Civil War. In 1878,the J.P. Tolman Company was foundedin Massachusetts, and the AmericanManufacturing Company (AMCO) wasfounded in Brooklyn in 1889. All ofthese companies survived independent-ly of the National Cordage Trust that
threatened to monopolize the industryuntil the Sherman Antitrust Act waspassed in 1890.
A significant milestone was achievedin rope technology when the TolmanCompany began incorporating rein-forcement cores in braided sash cords in1888. The company was then renamedSamson Cordage Works.
Synthetic Fibers: A New EraUntil World War II, ropes were made
from natural fibers, including manila,sisal, and hemp. The strongest of thesewas manila, a fiber that comes from theAbaca plant and grows in the PhilippineIslands. Sisal is a cheaper, coarser, andweaker fiber that grows in Mexico,Brazil, and Cuba. The quest for a syn-thetic fiber began when the U.S. lost thePhilippine Islands to Japan duringWWII. Dupont responded by develop-ing a nylon filament that was used inflak jackets and parachute shrouds.Nylon proved to be a good fiber for pro-ducing ropes. AMCO and its subsidiarySt. Louis Cordage Mills took advantageof the new technology by introducingthe first synthetic 3-strand nylon rope in1948. The strength of this new rope was2.5 times that of manila and 5% lightersize for size. Nylon did not rot, mildew,
or deteriorate when exposed to waterlike natural fibers. However, it did haveseveral drawbacks. It was expensive,had a very high elongation rate, andwould not hold up well when exposed tofrictional heat. Polyester was the nextfiber to be used for rope, proving to beas strong as nylon but with lower elon-gation, better abrasion resistance, andhigher melting temperatures.
Innovations Rapidly Advance RopeTechnology
Innovations through the 20th Centuryrapidly advanced the rope industry asdevelopments and discoveries weremade.• In the early 50s, AMCO producedthe first ropes from polypropylene.These ropes were half the weight ofmanila at twice the strength. They lastedlonger and were as economical as mani-la. The fibers could be produced on siteand the ropes could be made any color.This was the death warrant for manilaand sisal fibers.• In 1952, Herzog Rope was estab-lished in Richmond, B.C., Canada.Specializing in ropes for the Northwestfishing industry, Herzog developedPermaflex lead line for the seine indus-try in 1989.

• In 1957, Samson Cordage Works developed thefirst synthetic double-braided rope. This patented con-struction produced ropes far stronger, more durable,and easier to handle than the 3-strand twisted ropesmade since ancient times. • In 1972, Samson Cordage Works cooperated withOcean Systems, Inc., also of Richmond B.C., Canada,to develop the first double-braid synthetic-fiber ropeused to moor an oil tanker to a loading buoy located inthe North Sea. It was through this cooperation thatSamson Cordage Works and Ocean Systems united tobecome Samson Ocean Systems.• In 1992, AMCO achieved another milestone whenthey perfected the co-extrusion process and produced afiber that was 30% stronger and three times more abra-sion-resistant than polypropylene.
With the advent of high-modulus polyethylene(HMPE) fiber, rope making was primed for yet anoth-er era. High-modulus polyethylene provides thestrongest synthetic ropes in the world. The use oflightweight HMPE ropes revolutionized the industryagain, significantly affecting a multitude of industries.The marine industry in particular has benefited fromhigh-performance ropes that have increased crew safe-ty, and made operations more efficient and cost effec-tive. Hooven Allison continues to make natural fiberrope and synthetic cordage products, and GladdingBraided Products is also still in business, catering tomarine and military industries. In 1993, Samson OceanSystems, Herzog Rope, and AMCO merged to becomethe worldwide leader in high-performance cordage.
Now known simply as Samson, the company's trade-mark depicting Samson slaying a lion is the oldestactive registered trademark in the United States. In1996, Samson developed AmSteel-Blue usingDyneema to construct a rope that is, size for size, 1/7ththe weight and as strong as wire rope.
The Future of RopeToday, rope making is a science deepened by
research, development, and testing. The world of high-performance ropes is ever expanding. Samson contin-ues to pioneer new products for the marine industry,which include the first synthetic rope to exceed 3.3million pounds in breaking strength, a line of productsthat provide higher coeffciency of friction for bettergrip, a reduced-recoil rope, and a fire-resistant towingpendant. Anchored solidly by its history, rope technol-ogy has a long future.
