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.
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
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
Replaceable steel wear
plates protect feed surface
from material edges
Air silencers greatly
reduce noise to enhance
the operator’s environment Two shock absorbers
automatically control feed
head and material inertia
Main piston
rod is hard
chrome plated
and ground
Twin
external air
tubes are
stainless steel.
