1 RECEIVING INSPECTION
Before removing unit from its packaging, check for visual damage, especially if crate,
skid, or carton has been damaged in transit. Any damage caused by shipping should
be immediately reported to the carrier. If unit appears in satisfactory condition, remove
all packing and wipe rust preventive from rollers with mild solvent.
2 ASSEMBLY
The Stock Straightener is shipped completely ready for set-up and operation, except:
The Dancer Arm, on specified models, must be positioned for your stock line and
locked on the shaft by tightening the three screws in the clamp.
Stock Straighteners equipped with the optional 1 1/2 HP or 2 HP drive motor, do
not come with a plug-in power cord (as do the standard 3/4 HP and 1 HP units).
You must make the connection to a source of 240V, 60 cycle, single phase, AC
power for units without a plug-in power cord. See Connection Diagram A-15865.
3 LOCATION
Locate the straightener in your production line between the stock reel and the press.
Looking at the control panel side of the straightener, the stock passes through the
straigtener from right to left. Align the straightener so that its pass centerline is in line
with the pass centerline of the-die, reel, and stock being fed.
WARNING - THE STOCK STRAIGHTENER MUST BE LAGGED TO THE FLOOR
WITH BOLTS THROUGH HOLES IN THE BASE TO PREVENT
ACCIDENTAL TIPPING OF THE UNIT.
4 ADJUSTMENT AND OPERATION
Check electrical operation first.
WARNING - ONLY OPERATE THE STRAIGHTENER WITH THE TOP COVER
LOCKED DOWN AND GUARDS IN PLACE. KEEP FINGERS AND
CLOTHING CLEAR OF THE STRAIGHTENER AND THE STOCK.
BE CAREFUL OF SHARP EDGES ON THE STOCK.
4.1 DANCER ARM
The D.C. motor's speed is varied through a potentiometer and electronic control system
by the position of the dancer arm riding on the stock. With electric power connected,
but without stock threaded through the unit, turn the power switch ON and the green
4. 4
light will glow. Look at the large hex nut on the end of the main drive shaft in the left
side. Note that it is not rotating with the dancer arm resting at its low position. Raise
the dancer arm slowly by hand until the main drive shaft starts to "creep". Then, raise
the dancer arm to its upper stop limit. Note that the motor and shaft are running at
maximum rated speed.
The Speed Control for the D.C. motor has adjustable trimpots that were set at the
factory for best performance under most (average) conditions. If needed, their settings
may be changed to optimize your particular operation, as noted below. This Speed
Control is mounted on the inside of the hinged access door. (Ref. Drawing. A-15865)
CAUTION: ELECTRIC POWER SHOULD BE SHUT OFF BEFORE ACCESS
DOOR IS OPENED. IF ADJUSTMENT IS NEEDED WITH POWER
ON, STAY CLEAR OF ALL WIRE TERMINALS TO AVOID
ELECTRICAL HAZARD.
TRIMPOT LABEL LABEL FACTORY SETTING
MAX. Adj. for 90 VDC (120 VAC); l80 VDC (240 VAC)
MIN. Adjusted for No Creep
I.R. Fully Counterclockwise
C.L Fully Clockwise
Maximum Speed
Since the dancer arm automatically reduces "excess" speed, do not change this trimpot
following any stock acceleration.
Minimum Speed
If the motor creeps when the dancer arm is down, turn the pot counterclockwise just
enough to positively stop the motor. If there is an excessive dead band in moving the
dancer arm up from its low limit position until the motor actually starts, let the dancer
arm back down and turn the pot clockwise until the motor begins to creep. Then, back
off the pot setting slightly so that the motor is stopped again.
IR Compensation
If the motor does not respond quickly enough to dancer arm changes, turn the pot
clockwise until response speed is satisfactory and motor speed is stable. Too much
adjustment can result in unstable motor speed in some cases. "Ideal' setting gives
full-load motor speed same as no-load motor speed (with dancer arm position fixed).
5. 5
Current Limit
If the motor reacts too quickly to dancer arm rotation, causing jerky operation, turn the
pot counterclockwise until the operation is smoothed-out.
4.2 STOCK GUIDING
Stock is guided on entrance and exit rolls between special clamp collars, which must be
adjusted to keep your width of stock centered through the straightening rolls. With
power turned off, unlock and raise the top cover. Feed the stock over the tops of the
guide rolls and power rolls and under the pinch roll. With the stock centered, loosen the
screws locking the clamp collars, and-slide them to within 1/8” of the stock, and lock the
collars again.
.
CAUTION - Check to see that the stock is lying in a straight line from the reel to the
press feed, through the straightener, and square to the rolls. Feeding
material at even a slight off-square angle will cause it to be crowded against
one of the guide collars, which can result in severe edge damage. Refer to
Figure 1 below.
Figure 1
One simple method of detecting misalignment is to check the height off the floor of both
sides of your stock at the bottom of the slack loop to the press feed. They should be
equal. If the stock is observed to ride hard against one of the guide collars during
running, misalignment is the probable cause. When the stock is running straight, it will
wander back and forth between the guide collars, touching one and then the other due
to in-plane coil camber.
4.3 PINCH ROLL
Independent of the setting of the "straightening" rolls, which are also powered, the basic
traction to pull stock through the straightener is provided by the pinch roll. It must be
carefully adjusted for each thickness and type of material to be run. However, there
should be no need to readjust the pinch roll for feeding new coils of the same material.
6. 6
For initial adjustment to a particular stock, put a short length (3 to 5 ft.) of the material
through the straightener, and if necessary, back off the adjustment screws on the top
cover to enable closing and locking the top cover without having to force it down. With
the power OFF, turn down the pinch roll adjustment screw until you feel it tighten up. If
the self-locking thread makes it difficult to feel this point, move the stock slightly with
one hand while you adjust the screw with the other hand, until you feel the stock is
positively held by the pinch roll. Tighten the screw just enough so that you cannot feel
slippage with reasonable pull-back by hand. Do not tighten excessively.
Unlock and raise the top cover, remove the scrap length, thread the stock from the reel
through the straightener now, and lock the top cover back down. Turn the power switch
ON. Manually operate the dancer arm by moving it up to check stock advancement
under power. If there is evidence of slippage (e.g., unsteady movement of stock, or skid
marks on stock), tighten the pinch roll adjustment screw just a little more.
The straightener will satisfactorily pull stock from a non-powered reel for most intended
applications. Heavier materials may be fed to the straightener from a powered reel, if
needed.
4.4 STRAIGHTENING ROLLS
Material unwinding from a coil has a different amount of curvature with every wrap of
the stock. A fixed amount of upward (or reverse) curve is put into the material by the
entrance straightening rolls. When properly adjusted, the remaining rolls then flatten
this fixed curvature producing consistently flat stock.
Using the handle provided, the Idler Rolls (upper straightening rolls in the top cover) are
positioned by the Ferry cap screws. They must be adjusted initially for each new type of
material (thickness, width, temper, etc.) to be run. However, there should be no need to
readjust these rolls for new coils of the same material. Refer to Figure 2 below.
Figure 2
7. 7
The first (incoming) idler roll should be set down far enough to give a slight upward
curve to the stock. A normal setting would be about 60% of material thickness. Thicker
and softer materials require less setdown, thinner and harder materials more. Each
remaining idler roll should be set progressively less distance down (i.e., relatively
higher) than the preceding roll. The last idler roll should contact the stock lightly to work
the stock back to desired flatness. It may be necessary to make several trial runs with
power, operating the dancer arm manually for short inspection lengths, with slight
readjustments to get the best combination of settings. If there is an upward curvature in
the material leaving the straightener, and presuming material is coming from the top of
the coil, the idler rolls are set too far down and should be backed up' slightly.
4.5 MAXIMUM ALLOWABLE STOCK THICKNESS
The maximum allowable stock thickness depends on a number of factors. These
factors include the actual width of your stock, maximum line speed (in/min) available
from the particular gear set (one of four options), the size of motor installed on your
particular straightener, the nature of your material (yield strength, hardiness), and even
the amount of pull-back force from your reel in some extreme cases.
Refer to the table in Section 6 for the maximum thickness of "standard" stock (55,000
PSI tensile yield strength), for which your unit is rated with full rated stock width (4”, 8”
or 12"), and no pullback from the reel. In general, if you should be operating near a
maximum rated condition, an increase in material strength, or a significant pullback;
these conditions must be countered by a reduction in material thickness or width from
the maximum values shown to avoid overloading the motor or gears. Since the
combination of possibilities is infinite, it is impossible to give a quantative guide for all
cases.
As a rough guide, the following reductions would be sufficient to counter a pull-back
force of 50 lbs:
Model Reduce Thickness By Or Reduce Width By
4” Wide, #1 Gear Set 009” 8”
4” Wide, #2 Gear Set 009” 9”
4” Wide, #3 Gear Set 009” 1.2”

5 MAINTENANCE
5.1 Grease Fittings
Regrease fittings every 1,000 hrs of operation.
5.2 Gears
Brush on good gear grease every 500 hours of operation.
5.3 Guide Rolls
Squirt light oil into needle bearings and needle thrust bearings every 500 hours of
operation. Worn or damaged parts can be replaced by ordering new parts from P/A
Industries, or your nearest dealer. To properly identify a part that you need, by “P/A
No.", first check the marking on the P/A nameplate and using the table at the end of
Sec. 6, see what is included in your straightener where options are available, if you do
not already know.
The Mechanical Assembly Outline Drawing A-15318 and the Electrical Connection
Diagram, A-15865 show (roughly) what the parts look like and give an item reference
(A, B, C, etc.). These references (A, B, C, etc.) are used in the Parts List in the
Appendix. Where options exist for a specific item, check carefully to order the right one
for your straightener. Electrical Schematic and Connection Diagrams are included as a
trouble-shooting aid, if needed.
6 OPTIONS
P/A Stock Straighteners are built with several optional features. These are described
briefly for reasons below:
If you are uncertain about the description of optional features included in your
existing straightener, which you must know to order some replacement parts,
9. 9
refer to the marking on the P/A nameplate and the table given at the end of this
section.
If you are interested in modifying your existing straightener, perhaps to do a dif-
ferent job from that for which it was originally procured, consult your local P/A
sales representative or dealer, or the P/A factory.
If you are interested in procuring another P/A Stock Straightener for a new job,
with features different from your existing straightener, consult your local P/A
sales representative or dealer or the P/A factory.
6.1 WIDTH OF STOCK
Stock is available with maximum ratings of 4”, 8”, or 12”. While many parts are
interchangeable, it would probably be uneconomical for a user to replace all of the parts
needed to modify an existing straightener from one width to another.
6.2 ELECTRIC MOTOR
Motors are available with special D.C. motors rated at 3/4, 1, 1 1/2, or 2 HP. The
mounting of all four motors in the base cabinets is the same. The controls and line
supply power for the motors is different in each case. The "standard" motor for the 4”
and 8” wide straighteners is 3/4 HP. The standard motor for 12” wide motor is 1 HP.
Consult the factory, if you need confirmation about a proposed modification.
6.3 GEAR SETS
There are four different gear combinations available capable of giving maximum line
speeds for the different width models, as shown in the table below. (All four motors
have the same maximum RPM.) The optional parts comprising each gear set include
five parts shown in the mechanical parts list and assembly outline as noted below.
Item Description
Item Q, Worm, 2T, or 4T
Item R Worm Spacer, used with 4T Worm
Item U Worm Gear, mates with 2T or 4T Worm
Item AD Change Gear, 18T or 24T
Item AH Idler Gear Bracket, used with 18T or 24T Change Gear
These parts can be interchanged, easily.
10. 10
6.4 SPEED CONTROL
Automatic, variable speed control of the motor to maintain a slack loop is done with a
dancer arm type of loop sensor, acting through an electronic speed control ("Black
Box"). This speed control is different for each horsepower rated D.C. motor.

7 WARNING, SAFETY FOR POWER PRESSES, AND WARRANTY
WARNING!
This equipment offers various means of operating or controlling machines. The operator must not be in or near the point-
of-operation of the machine, or the operating parts of any equipment installed on the machine, or bodily injury could result.
The EMPLOYER must post adequate warning signs onto the machine with proper warnings for his machine and the
specific application to which the machine and equipment are being applied.
Occupational Safety and Health Act (OSHA) Sections 1910.211, 1910.212, and 1910.217 contain installation information
on the distance between danger points and point-of-operation guards and devices. No specific references have been
made to which paragraph of OSHA 1910.211, 1910.212, 1910.217 or any other applicable sections because the
paragraphs may change with each edition of the publication of OSHA provisions.
All equipment manufactured by us is designed to meet the construction standards of OSHA in effect at the time of sale,
but the EMPLOYER installs the equipment so the EMPLOYER is responsible for installation, use, application, training,
and maintenance, as well as adequate signs on the machine onto which this equipment will be installed.
Remember, OSHA says that the EMPLOYER must use operating methods designed to control or eliminate hazards to
operating personnel.
It shall be the responsibility of the EMPLOYER to establish and follow a program of periodic and regular inspections of his
machine to insure that all their parts, auxiliary equipment, and safeguards are in a safe operating condition and
adjustment. Each machine should be inspected and tested no less than weekly to determine the condition of the
machine. Necessary maintenance or repair of both shall be performed and completed before the machine is operated.
The EMPLOYER shall maintain records of these inspections and the maintenance work performed.
Our Company is not responsible to notify the user of this equipment of future changes in State or Federal laws, or
construction standards.
SAFETY PROGRAM
Accident free operation will result from a well developed, management sponsored and enforced safety program.
Of vital importance to any successful program is the proper selection of guards and devices. However, there is no safety
device that will bring “automatic” safety to your operation.
Of equal importance to this proper selection of the guard and the device is the training of your personnel. Each person
must be trained as to the operation of the guard or safety device, highlighting why they have been provided on the
equipment. Rules for safe operating should be written and enforced at all times. A final major concern of an effective
safety program is regularly scheduled inspection and maintenance of all of the equipment.
To ensure continued safety at all times, top management, line supervision, safety engineers and all employees must
assume their proper share of the responsibility in the program. Only as a group, one that knows your own operation and
its problems, can you carry out an effective safety program.
To assist you in the development of and continued use of safety programs, many safety minded groups have made
guidelines available to you. However, you must know when and how to apply these guidelines. The manufacturer
provides information to assist you in properly adjusting and maintaining your equipment. There is no short cut to proper
safety; therefore, it is recommended that you comply with their recommendations at all times.
WARRANTY
We warrant our new parts against defects under normal use and service for a period of 12 months after date of shipment.
Our obligation under this warranty is limited to replacing or repairing (at our option) the defective part without charge,
F.O.B. our plant in Bloomfield, Connecticut. The defective part must be forwarded to our plant, freight prepaid, for our
inspection prior to replacement or repair. EXCEPT AS EXPRESSLY PROVIDED HEREIN, THIS WARRANTY IS IN LIEU
OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING A WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. Furthermore, the seller does not warrant or represent that the equipment
complies with the provisions of any law, particularly including the Occupational Safety and Health Act of 1970, and
regulations promulgated thereunder. In no event shall we be liable for special, indirect incidental or consequential
damages, however rising.
