At one time straightening was a simple bending
operation with the addition of some readily calibrated
“overkill” to compensate for springback.
The challenge of longer lengths, played off a spool,
was met by running the tube through a series of
precision rollers.
Twists even of the spaghetti variety quickly yielded to
a couple of V-blocks and a judiciously placed manual
press. But the tubing industry did not linger very
long in its early stage, and straightening was key to
progress into the era of nasogastric tubes, cathode ray
tubes, and nylon stuffing tubes.
It continues to be pivotal today, in the hands of the
successors to the pioneers of straightening technology
and equipment.
A representative selection of their products and
services will be found in the pages of this section of
