Machine use to turn the yarn into strands
History of the Plymouth Cordage Company at
Mystic Seaport Connecticut
Several strands twist makes a rope
For thousand of years, humans have used twisted fiber rope
for many purposes.Rope is well known for all of us
but we probably most of us don't know much about how is made.
Raw plant FIBERS are spun together to form a YARN
the twist is usually made left to right.
Several YARNS are twisted together to form a STRAND.
the twist is always opposite to the twist of the yarns.
STRANDS (usually 3, but sometimes 4 or 6)
are laid-twisted together to form a ROPE.
This twist is always opposite to the twist of the strands.The opposing twists in each step keep the rope from unraveling.
