Rapid-Air STRAIGHTENER and PUSHBUTTON RAPID-ROLL: SC SERIES - Manual (Page 10)

Maintenance
Use MOBILE 600W cylinder oil or
equivalent. This is a non synthetic oil.
Rolls:
Although the rolls should be cleaned
periodically they never have to be
greased as all the rolls have perma-
nently lubricated bearings.
Drive Belt:
At the oil change interval, check for
belt tension and wear.
Gear transmission:
The reservoir oil capacity is about 3
to 12 oz. depending on the size of the
straightener. The reservoir oil should be
changed every 2000 hours and should
be filled to the oil level site gauge.
Lubrication
Once the straightener has been
tested and all the functions work
then it should be tested for what it
was designed to do and that is to
remove coil set.
Retract all of the idler rolls and the
exit pinch roll to a position so when
the cover is closed the material is
not being deformed. Open the cover
of the straightener and position the
edge guides for maximum width. Cut
and place about a four foot length of
the material onto the straightener
rolls with the exit end of the mate-
rial extending through the exit pinch
rolls and centered from side to side
in the straightener. Close the cover
and latch it. Adjust the exit pinch roll
enough to grip and hold the material.
Adjust the edge guides so that they
just touch the material.
Adjust the first idler roll knob, this is
the one nearest the entrance of the
straightener, so that it deforms the
material no more than the thickness
operation
of the material. Adjust the second
idler roll knob so it is lightly on the roll.
Run the material to check that the exit
pinch roll is not slipping on the mate-
rial, readjust if necessary. This piece
will still have coil set in the first two
feet of the material as it was not run
through the complete straightening
cycle. At this time, this piece could be
rerun and checked for straightness or
a new piece could be cut and run and
then be checked.
A good check is to guide the exiting
material, keeping it parallel to the
rolls, until the run is complete and then
hold one end of the material in the air
while peering down the length of the
material. If the material still has “coil
set” then readjust roll pressure on the
last roll, towards the exit end but before
the pinch roll, until the material is
straight. Run one or more short length
setups while making final adjustments.
Once the proper setting has been de-
termined, the quick release top main-
tains the adjustment during loading.
Thread the material from the reel
through the straightener, under the
dancer arm, and into the pulling
device leaving ample loop between
the straightener and the pulling
device. If the material thickness
is such that when exiting the
straightener, it will not let the
dancer arm down to the rest
position, then either lengthen the
dancer arm or adjust the loop height
until the straightener stops feeding.
Set the % speed potentiometer to
50% for a starting position and
start the pulling device to have
the material feeding. If the straight-
ener gets finished and stops before
material is needed again then the
straightener is set to feed too
fast, slow it down by adjusting the
% speed potentiometer. The ideal
straightening is to have the
straightener slightly exceed the
feed rate required. This minimizes
the starting and stopping and
resultant stock deformation.
