Ropes have been in use since prehistoric times for lifting, moving, hanging and securing items in place in both households and industries. Although it is simple, its making is not. This article delves into details of both traditional and modern rope manufacturing
Traditional Rope Making
In the past, rope making was manual and tedious, a process that was referred to as a rope walk. It was, as it is now, important to make a rope with a high elastic recovery, which means that it could withstand stress without breaking easily. Ropes were made from natural fibers such as sisal, cotton, hemp or animal fur. The rope makers first combed these fibers to remove seeds or clumps, and then laid them out to a length that was equal to that of the intended final product. Next, they hooked one end of the fibers to a spinning wheel and used their hands to pull and twist them in a clockwise direction to form yarns. These were then fastened to a machine, which helped to weave them in anti-clockwise direction to form strands. The number of yarns in a strand depended on the intended diameter of the final rope. For instance, ropes meant for making rafts were usually thick and required more than a dozen yarns per strand. The final step was to twist the strands in a clockwise direction to create a rope and make a loop at the end to keep them from unraveling. The use of clockwise and anti-clockwise twisting styles was for the purpose of locking the individual components to keep them from untwisting.
Modern Rope Manufacturing
Today, ropes are made from both natural and synthetic materials. The synthetic kind is more durable than natural materials. The latter are often for ropes for decorative purposes such as in creating rustic designs. Synthetic materials, on the other hand, are used for making ropes for both household and industrial purposes such as hanging objects and anchoring large ships. They include nylon, polyester or wire.
For natural fibers, they are fed into several machines where they are coated with natural oil to keep them from tangling, then cleaned and compressed into a ribbon. Next, they are twisted to form yarns and wound into bobbins, colored, then put into a compression tube which twists them into strands. Finally, a closing machine is used to braid the strands into a rope.
For synthetic fibers, color is added in the first stage when the raw material is in liquid form. As a result, the final product does not bleach out easily. The liquid is then extruded from a machine to produce solid fibers. The final process involves twisting the fibers into strands, and then twisting these again to create a rope.
Ropes have been in use since prehistoric times for purposes such as lifting, tying together and moving objects. Traditional rope manufacturers was done manually with few machines to aid the process, while the modern way is quicker and automated. What’s more, in the past, ropes were made from natural fibers only, while today, both natural and synthetic ones are used.
