Operational Information
When removing a cone-rod, it is necessary to release the tension in the
straightener, and remove its front reinforcing plate to allow the cone-rod easy
exit. To do this, follow the instruction listed below.
1. Remove the cone from the end of the coiled rod, taking great care
when the threads are undone to ease the cone and coiled rod apart
to gain access to the connector inside, easing this apart without
damaging the wires.
2. Loosen the lock nuts fitted to the roller adjuster bolt, protruding
from the side of the straightener, approximately one turn.
3. Loosen the roller adjuster bolt, and screw it out as far as it will
move.
4. Remove the four nuts holding the front reinforcing plate on, remove
the plate, and then loosely refit the nuts to prevent accidental loss.
5. Loosen the four cap bolts that hold the scraper blocks on the bottom
of the straightener, slide the blocks out as far as they will move, and
retighten the bolts by hand to prevent accidental movement.
6. The rod can now be pulled out of the gap between the rollers.
When refitting a cone-rod, the above procedure can be followed in reverse
order, but before the final operation of tightening the lock nuts, the
straightener must be correctly adjusted, as discussed below.
Straightener Adjustment
Whenever a new rod is fitted it is necessary to reset the tension of the
adjustable roller in the straightener assembly. For this operation the unit
needs to be raised to allow a 1-1.5m push of coiled rod to be pushed out,
where it can be observed for straightness. It is possible to set up the
straightener using either the manual inverter, or the main system.
Warning:
If the main system is to be used, the operator should have direct
view of the operation from the controlling computer, and the
maximum push distance set to less than the raised height. Using the
manual inverter requires special care as this removes all safety
features of the operating software.
The procedure below should be followed for setting the straightener.
1. Tighten the adjustable roller by hand, until it is in contact with the
cone-rod.
