Preforming
Preforming preshapes strands before the rope
is closed. This process helically shapes
the wires and strands into the shape they will
assume in the finished rope. It improves handling
and resistance to kinking by conforming the
strands to the position they take in the rope.
The superior qualities of preformed ropes
result from wires and strands being "at
rest" in the rope, which minimizes internal
stresses within the rope. Today, preforming
is virtually standard in rope manufacture, and
non-preformed rope is made only on special order.
