these ropes are made from thousands of
nylon fibers that are finer than human
hair but stronger to make rope yarns
wind around aluminum cylinders pulled by
a turning spool down the line
then three at a time the yarns roll over
another spool that applies to protective
coating of urethane they funnel through
a distribution plate that holds them
evenly apart this ensures they're at an
even tension as a rocking spool twists
them into one larger yarn
[Music]
this machine is called the whirlwind it
twists the yarn and then winds it onto a
take-up spool inside
a little arm moves back and forth
guiding the yarn so it winds evenly onto
the spool this is core yarn and will be
used to make other rope now dozens of
spools of nylon fiber unwind at the same
time to make jackets to protect the core
yarns the fibers travel several feet
over a network of rollers that act as
guides and control tension on each
individual fiber they pass through
distribution plates as turning bobbins
below twist the fibers into yarn a
[Music]
platform moves up and down to evenly
wind the yarn onto the bobbin they place
48 of these bobbins on the Maypole
machine so called because the braiding
action resembles a dance around a
traditional maypole the bobbins spin and
zigzag around each other
as the machine pulls core yarn up
through the center here you can see the
Rope being braided around the core yarn
as it's pulled off through a die this is
the braiding action in slow motion
[Music]
it produces a mountain climbing rope
strong yet stretchy because of the twist
and the core of the Rope the rope winds
onto the wheel as it pulls it upwards
then it spills into a basket
