AIR FEED FEATURES
FASTER SPEEDS
Our patented system sequences
high speed models up to 400 cycles
per minute at full two inch pitch.
VERSATILE
Coil stock can be fed in any direction
or angle at any time during the
machine cycle. A single feed can
push or pull through long or short
progressions. A variety of stock
widths and thicknesses can be fed at
different speeds and feed lengths.
Two or more strips can be
simultaneously fed by the same feed.
INEXPENSIVE
The cost of P/A feeds are 65% to 90%
less than conventional roll or slide
feeds. With savings like that you
should consider leaving the feed
permanently mounted on the tool
to decrease set up time and increase
productivity.
Surveys show that Contract Job
Shop Stampers prefer P/A air feeds
because they are the easiest and most
economical way to change from one
job to another.
Actuating valve or optional
remote actuation controls feed
motion and clamp sequencing
Speed adjustment screw
controls feed head velocity
and material inertia
Two (or four) drilled
holes provide easy
mounting to die shoe,
bolster, or mounting
bracket
Oversized air inlet
eliminates air pressure
volume problems
Air silencers greatly
reduce noise to enhance
the operator’s environment
Modern Cup Wiper Seal (instead of “O” Rings) maintains
clean piston assembly and significantly increases cycle life
Body constructed of hard-coat
anodized, aircraft aluminum for weight
reduction and minimal wear characteristics
Replaceable steel wear
plates protect feed surface
from material edges

SIMPLE INSTALLATION
Our feeds are extremely easy to mount.
Two (or four) mounting bolts and a single
air line connection are all that’s necessary.
A compact, clean design permits the P/A
Air Feed to be mounted right on the die set.
QUICK SET-UP
Adjustments are quick, simple and positive.
To change feed length, turn the adjustment
screw to the desired pitch between positive
stops and tighten the locknut.
PATENTED DESIGN
Technologically the BEST air feed on the
market today! U.S. Patent No. 4,444,346.
REPEATABILITY
Consistently holds ±.001" (.025mm) stroke
after stroke. The most precise press feed
available at a reasonable cost.
HANDLES VARIETY OF MATERIALS
Paper, plastic, foil, fabric, wire, tubing
...you name it and P/A will feed it. Highly
polished materials or extrusions, preformed
or irregularly shaped materials – all can
easily be adapted with special clamps.
3
Page 6
MOUNTING THE AIR FEED
Its compact design will allow this Feed to be installed
on the Die or Press Bolster, or on many types of
machines, at any angle, including upside down or
vertical. Use two (or four) minimal clearance HoldDown Bolts to solidly fasten the Feed as close to the
Work Station as possible. NEVER use ‘C’ clamps as
the Feed may move or shift position.
CORRECT
NOT
CORRECT
Mounting directly
on the Die is
recommended
for “Just-In-Time”
production and
to reduce set-up
time.
The top of the Feed Wear Plate should be level with
the lower Die Face and the front of the Feed square
and centered with the tool.
A mounting
bracket provides
easy vertical
adjustment for
tools with different
stock line
heights.
The Feed can be
moved from
press to press, or
die to die, in a
matter of minutes.
4
Page 7
AIR POWER SUPPLY CONNECTION TO THE FEED
A single air line connection is all that is needed for
maximum power with minimum air consumption. We
strongly recommend that an oversized air hose be
connected to the Feed with a water separator type
filter and air line oiler.
The use of a 3-Way On/Off Exhaust Valve will make
minor adjustments and strip insertion easier.
RECOMMENDED AIR LINE CONNECTION
TO ELIMINATE MOISTURE AND PARTICLES FROM MAIN LINE
Set the Air Pressure Regulator between 80 and
120 PSI (6 to 8 Bar).
FEED LUBRICATION
Fill the air line lubricator with a good grade of
hydraulic cylinder oil, like Shell Tellus 32. Set for one
drop per minute to properly clean and lubricate all
internal parts.
NEVER use Spindle Oils, Motor Oils, Solvents,
WD-40, or Stock Lubricating Oils. Use of these types
of oils will cause Feed performance to deteriorate, as
well as premature wear.

Page 8
PRESS FEED TIMING
The Reciprocating Linear Motion of the Feed Slide must
be timed to the press crankshaft rotation for optimum
performance. The Actuating Valve’s vertical motion
controls the sequencing of the Stock Clamp, Feed
Clamp, and the Feed Slide.
To understand how the rotary crankshaft and linear
Feed Slide motion work together in a Press Feed Cycle,
it might be helpful to visualize a Clock Face. The
position “Top Dead Center” of the Ram Stroke would be
12 o’clock, half way down would be 3 o’clock, “Bottom
Dead Center” is 6 o’clock, and moving half way up
would be 9 o’clock.
The optimum Feed cycle requires two thirds of the
crankshaft rotation (240 degrees) to feed the material
into position. During the remaining 120 degrees, the
Feed Slide returns to the Stop Screw for more Material.
As soon as the Stamped Part has been ejected and the
Punches are clear of the Die (approximately 8 to 8:30
on the clock), the Feed Clamp will grip the Stock and
then the Feed Slide will begin moving towards the Feed
Body.
CAUTION: To properly complete a Feed Stroke, the
Feed Slide must have enough time to contact the Feed
Body before 4 o’clock and then return to the Stop Screw
before 8 o’clock during the 360 degree crankshaft rotation
otherwise erratic short feed progressions will occur.
6
Another method of controlling the Feed Timing is
to use the Remote Electric or Pneumatic Actuation
Systems to suit the Press and Part applications.
These methods require the same 240° feed and 120°
return timing cycle.

CONTROLLING THE FEED
MECHANICAL ACTUATION
Install a Support Bar with a Plunger on the upper Die
Block of the Tool or on the Press Ram. The vertical
Plunger should be threaded to allow vertical height
adjustments. The Plunger should contact the center
of the Feeder’s Actuating Valve Stem. After contact,
and during the first 1/4" (6mm) of downward Valve Stem
travel, nothing happens with the Feed Slide Control.
During the next 3/16" (5mm) of travel, the Mechanical
Actuation Valve opens causing the clamps to shift and

the non-feed stroke begins. The remaining downward stroke of the Valve Stem is over-travel.
When the Press Ram passes BDC and begins to
move upward, the Valve Stem reverses travel direction.
As the Plunger moves off the Valve Stem, the
Mechanical Actuation Valve closes causing the clamps
to shift and the Feed Slide to begin the feed stroke.
Installing a Spring on the Plunger to contact the
Actuating Valve Stem will result in a more desirable
Feed Cycle for Presses with long strokes.

CONTROLLING THE FEED FEED LENGTH ADJUSTMENT
REPEATER CONTROL SYSTEM
The Air Feed can be multiple stroked for each cycle
of the Press to obtain greater feed length increments
than the Air Feed’s maximum feed stroke capacity.
The Repeater Control has a digital counter and Key
Lock Selector Control for “Feed Control Press” or
“Press Control Feed”. Used with Remote Electric
Actuation and 120 VAC, 50/60 Hz Power Supply.
Transformers for other voltages are available.
For coarse feed length adjustment there are
counter-bored holes provided in the side rails of the
Feed. Move the Stop Block, and insert and tighten
the Shoulder Screws in the holes closest to the
desired feed stroke.

Page 14
MATERIAL ADJUSTMENT
STEP 1. The strip material must be straight and
parallel from the Rear Stock Guides through the
Feed and into the Tool.
STEP 2. Adjust the two Roller Stock Guides with
enough lateral clearance for camber and variations
in stock width.
STEP 3. Recommended vertical clearance between
the Material and the two Clamps is .010" to .020"
(.3mm to .5mm). Adjust by holding the Clamp
Piston Stem with a Hex Key and turn the Hex Nut.
CAUTION! It is very important to have a level Clamp
condition for both the Feed Clamp and the Stock Clamp.
12
Page 15
SPEED CONTROL
The Speed Adjustment Screw is located on the side
opposite the air inlet. It provides material velocity
control during the feeding direction of the Feed Slide.
HOW TO SET
1. Cycle the Feed manually, turning the Speed
Adjustment Screw clockwise until the Feed motion
becomes erratic or incomplete.
2. Turn the Speed Adjustment Screw counter-clockwise until Feed Slide makes a complete forward motion.
3. Turn the Speed Adjustment Screw an additional
half turn counter-clockwise.
4. If the material slips forward under the Clamp upon
impact with the Main Body, turn the Speed Adjustment
Screw clockwise 1/4 turn or until slippage stops.
CAUTION!
Never open the
Speed Adjustment
Screw more than
three complete turns.

THREE PILOT RELEASE METHODS
MECHANICAL PILOT RELEASE
The Mechanical Spring-Loaded Pilot Release Clamp
is installed in place of the standard Stock Clamp.Turn
the Hex Nut to compress the Spring for the desired
clamp and material pressure. Not available on LX.
PNEUMATIC PILOT RELEASE
The Pneumatic Pilot Release can be used for those
applications that require more sensitive clamping
pressure, or that the Clamp pad be completely free
of the material. With this system, the clamping
pressure may be adjusted by regulating the air
supply to the valve. The clamp pad is fitted with a
quick-response cylinder for positive stock grip and
release. Timing is controlled by an external 4-way
Solenoid valve or spool valve.
