If the straightener is made to correct a clockwise
curvature, it is often impossible to correct a
counterclockwise curvature. The only available
adjustment is the variation of the degree of bend
at each station. This is true even for straighteners
that have banked upper rolls that pivot for
two-point adjustment.
To more easily explain the concept, Figure 8
shows a three-roll combination with the upper
roll forward and Figure 9 shows a three-roll
combination with the upper roll to the rear.

Stock Straighteners
vs.
Straighteners with
Traditional
Vertical Roll
Adjustment
CONCEPT: The concept behind a movable
platen containing the upper bank of rolls for
straighteners can be somewhat difficult to
grasp, but once the principles are understood
the superiority of this system becomes obvious.
To explain the differences between the adjustable platen system and one that uses traditional
single-point vertical roll adjustment, we are
describing both types of systems here.
VERTICALLY ADJUSTABLE UPPER ROLLS:
For centuries the bending of materials has been
done by variations of a three-roll arrangement as
illustrated in Figure 1.
Figure 1
Downward curvature of material
to remove coil set
Bending occurs when one roll is forced into the
space between the other two rolls for downward
curvature of the material to remove coil set.
Pressroom straighteners add multiple three-roll
combinations in order to level the material in
small increments at each stage. This method can
provide acceptable results for some materials,
but is limited because correction of material
curvature is effective in only one direction as
illustrated in Figure 2.
Figure 2
SIX-WAY UPPER ROLL ADJUSTMENT: After
manufacturing straighteners with vertically
adjustable rolls for many years, Rapid-Air
developed and patented the adjustable platen
type straightener as illustrated in Figure 3.
Figure 3
Forward/Back
Up/Down
Up/Down Slant
This design mounts the upper rolls in a platen
which can be adjusted for degree of bend as
illustrated in Figure 4 and Figure 5
Figure 4
Light material distortion
Figure 5
Heavy material distortion
Less deflection
Deeper deflection
and for curvature direction as shown in
Figure 6 and Figure 7.
Figure 6
Rolls forward – curve up
Figure 7
Notice that the sharpest bend occurs where two
rolls are in close proximity. When the upper
roll is forward, the curvature will be up and
when the forward roll is adjusted to the rear,
the bend will be down. The degree of bend can
be adjusted by a combination of vertical and
horizontal adjustments.
ADVANTAGES: The high degree of flexibility
afforded by the adjustable platen design provides
a predictable straightening method for a wide
variety of materials and takes a lot of the “Black
Magic” out of pressroom straightener setup.
The reduction in the flexing and distortion of
the strip of material and the reduction of the
straightening power required allows effectiveness with heavy materials. Additionally, the ability
to place rolls in a proper close proximity allows
effective straightening with very thin materials.
ROLL DIAMETER: The smaller the roll
diameter in a straightener the better it is able to
remove distortions in the strip of material, but
this factor is compromised by the requirement
of larger rolls in wider models of straighteners
in order to prevent deflection of the rolls
themselves. Rapid-Air straighteners are designed
to optimize all factors (including number
of rolls, diameter and position) within the
published material capacities and specifications
for each model.
SWING-OPEN TOP: Rapid-Air developed and
introduced the swing-open top for straighteners
in order to facilitate the cleaning of rolls and the
threading of a new strip of material through the
straightening rolls. For convenience and safety,
each top is counterbalanced and held in the
open position until it is clamped for operation.
Roll adjustment settings are maintained when the
top is closed and locked.
AVAILABILITY: All models of Rapid-Air straighteners are presently available with the adjustable
platen design with an expanded range of models
being introduced in the coming months.

Operating Instructions For SBX Series Powered Straightener
The straightener that you just
received is fully assembled and tested
and ready to be put into position.
CAUTION: Due to shipment vibration,
the straightener should be checked to
be sure that all screws and bolts are
secure and all electrical components
are in place inside the cabinet. Visually inspect the complete machine for
physical damage due to shipment and
handling. If the straightener was damaged in shipment, contact the carrier
first and then Rapid-Air.
Install the straightener on a level
surface with sufficient clearance for
loading the material and adjusting
the roller pressure for straightening.
Align and center the straightener to
the device that it will be supplying the
straightened stock. The straightener
should then be bolted to the floor
especially when used to pull stock
from a non-powered reel.
CAUTION: Before bolting the
straightener down, check for the
longest feed length to be run. The
straightener should be set so that
there will be about two or three feed
lengths in storage in the loop without
re-inducing coil set in the material.
The standard speed straightener
is completely self contained and
only needs to be plugged into a
20 amp, 120 VAC, 60 HZ outlet. If an
extension cord is used as a source
to the straightener power, it should
be a minimum 12 gauge wire to keep
the voltage losses down and also for
electrical safety reasons.
Please check your local safety codes.
The medium and high speed
straighteners require 230 VAC, 60 HZ,
1PH as the supply voltage. Please
refer to the schematics in the manual
for required fuse sizes.
Please check your local safety codes.
Turn on the main power button and
run a test cycle checking the jog
(using the jog button) and run
(using the dancer arm to test that the
speed varies if using the proportional
control). Test all electrical features
before continuing.

Start up procedure
Prior to applying power to the machine the operator should review all the controls on the machine. A brief summary of the
controls is listed below.
Main Console And Controller
The main pushbutton control box is
mounted on the top of the straightener frame. Located on the face of the
console are eleven pushbuttons, one
display, one on/off switch, one circuit
breaker, one external loop plug and
inside the box is motor board and one
potentiometer when required, all of
which are explained below.
1. % SPEED POT
The % speed function adjusts the
maximum speed that the straightener
will feed and should be set to maintain a constant feed rate. Adjustable
in the run mode.
2. ON/OFF SWITCH
This illuminated switch is the main
power switch for the controller. It must
be “ON” for the machine to function.
3. RUN/STOP/JOG
SELECTOR SWITCH
This function selects between Run,
Stop and Jog. If in Run and the control
arm is moved the rolls will turn. If in
Jog, the Jog button has to be de-
pressed for the rolls to turn. If in Stop,
there should be no movement of the
rolls even if the dancer arm is raised
or lowered or the jog pushbutton is
pressed.
4. JOG BUTTON
Used for intermittent movement of
material on the rolls, mainly used for
set up or getting material thru the
straightener and over to the pulling
device. Active in jog mode only.
5. DANCER ARM LOOP HEIGHT
AND RANGE ADJUSTMENT
a. Loop Range – The loop range func-
tion adjusts the amount the dancer
arm will travel to provide the full
range of speed of the straightener.
There are eight positions available.
b. Loop Height – The loop height function is used for setting the start position of the control arm. The setting determines when the straightener rolls
will start turning. Each position will
move the operating start position up
from the home position to accom-
modate specific material rest height
requirements.
6. LOOP ARM / EXTERNAL SWITCH
This switch selects either dancer arm
(internal) by displaying “LV” for loop
arm vertical reel or “LH” for loop arm
horizontal reel (PMD) or external loop
control by displaying “RT” for the
RTB and ”RS” for the RS_1. The RLL
will work on the “RT” selection.
7. RESET BUTTONS
a. 15 amp – This is the main circuit
breaker for the 120 VAC input
straightener.
8. REMOTE INTERFACE
PORT “D” CONNECTOR
This connector is used to communicate with external loop control equipment.
CAUTION: Never plug any type of computer or non Rapid-Air equipment into
this plug or severe damage will result.
Always consult with the factory when
installing new external controls for
compatibility and wiring information.

dancer arM loop
Dancer Arm Loop Height Adjustment
Eight different loop sensing arm
operating positions can be selected
during set-up. The material thickness
determines the dancer arm rest
position. Once the material is
threaded up and the dancer arm
is resting on the material and the
reel runs in the rest position then
select a higher number on the height
adjustment until the reel stops
rotating. The zero point of the dancer
arm is raised from its no material rest
position to the current rest position
angle shown (as indicated 0-8). The
dancer arm will start the material
dereeling from the new rest position
selected. The function is active and
can be changed in the run mode.
Dancer Arm Loop Range Function
The loop range function selects the
degree of arm movement to achieve
maximum motor speed selected. If a
loop range of “0” was selected then
the arm would only have to move
approximately 10 degrees to have the
reel at full speed whereas if the loop
range “8” was selected then the arm
would have to move almost the full
travel or approximately 90 degrees to
get to full speed. The function is active
and can be changed in the run mode.

dancer arM adjuStMent explanation
JOG SPEED AND DANCER SET-UP
The straightener was shipped with
the dancer arm set up for its correct
position so the only thing that has to
be reset would be the jog speed if you
need it to jog faster or slower. The
rest of the keypad is pretty much self
explained so become familiar with the
keypad positions for making adjustments on the fly. Turn on the main
power switch and select “LV” for loop
arm vertical at “Loop Type” on the
pushbuttons.
MAKING INTERNAL
PROGRAM ADJUSTMENTS
Turn off the main power switch,
press and hold the “Run/Stop/Jog”
button while turning the main
power switch on. The first screen
you see will display the jog speed
percentage.
JOG SPEED 23% +
NEXT -
If you want the jog speed faster
then press the “Reel Speed “+ ““ %
speed pushbutton. If you want the jog
speed slower then press the “Reel
Speed “-”” % speed pushbutton. The
jog speed is shown in percent of max
jog speed. If the jog speed is “OK “
then push the “Run/Stop/Jog button”
once for next.
The next screen asks if you want to
set up the sensor. As before the percent speed buttons are used for the
yes-no. Select “no” if all you wanted
to do was set the jog speed. Select
“yes” if you want to reset the dancer
arm position setup. And then “next”.
SETUP SENSOR YES
NEXT NO
The next screen asks you to set the
low set point. If the dancer arm is at
“No Material Rest” then just save
the setting by pushing the Stop/Run
Jog pushbutton.
SENSOR LOW SETPOINT
SAVE XXX
The next screen is for setting the high
set point. Raise the dancer arm to
its upper stop position and press the
save or Stop/Run/Jog button once.
SENSOR HIGH SETPOINT
SAVE XXX
The next screen is to set the offset of
the program. Potentiometers are hard
to get set from left to right so we built
in an offset. If you set the low and
high range and go into run and the
reel runs for no reason then an offset
has to put in. Go through the setup
procedure again and put in an offset
of –3 to –5 and now the pot is zero.
LOW OFFSET + 0 +
NEXT -
You have now set the dancer arm
limits. The next screen is to exit the
setup and start working

Standard Straightener coMponentS
Curve Up/Down Adjustment
Some applications have dies that cannot accept anything but flat stock
and other dies run better with the material curving up or down to miss the
built-in edge required in the die. Before this feature was added, operators
would under straighten or over
straighten the material to suit their
needs but in doing so would severely
change the material entering the die.
This not only caused feeding problems but part quality problems. With
this feature, curve up or down can be
accomplished by changing the position of the rolls without stressing the
material.
optional Straightener coMponentS
Entrance Cascade Roll
The entrance cascade roll assembly
is used to maintain a support arc for
stock entering a feed. The cascade
roll has three extra rollers to help the
material flow better.
Exit Cascade Roll
The straightener is shipped with
the exit side pre-drilled for the
cascade roll or guide roll block.
The entrance and exit use the
same components.
Entrance Guide Roll Block
All straighteners are shipped with
an entrance guide roll block. This
contains a roller and two adjustable
edge guides.
Angle Bracket
Rapid-Air offers this accessory that
mounts between the straightener
head and the base. It angles the
exit side of the straightener twelve
degrees lower than the entrance
side. This feature works very well
when using the straightener to pull
off a non-powered reel.
9
operation
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 material 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
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 material, 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 determined, the quick release top maintains 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 straightener 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.
Maintenance
Lubrication
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.
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
10
greased as all the rolls have permanently lubricated bearings.
Drive Belt:
At the oil change interval, check for
belt tension and wear.
