The PRF 0200 SLCOD Feed features the following:
Mechanical Features:
Smooth steel finish rolls.
Steel frame
Permanently lubricated anti-friction bearings
Gears between top and bottom rolls
Two adjustable stock entry guides Cam rollers with handles. No tools
are required for adjustment.
Horizontal hold-down rollers at feed input These entry rollers keep
material from jumping the stock guides during very high
acceleration.
Precision long life Kevlar timing belt Less elastic than steel, Kevlar belts are the ultimate choice for speed reduction in servo systems. We warranty the belt for 10 years.
Air pilot release: Used for releasing the feed rolls, allowing pilot pins to take control of strip position, or to help compensate for defects in strip geometry. Waddington feeds feature one of the fastest air pilot release systems in use today.
Electrical Features
Brushless low-inertia Servo Motor With high temperature windings and
internal thermal protector
Feedback Very high resolution Very accurate and Very rugged.
Everything required for the best performing servo feed.
Motor Connectors Only the highest quality motor and feedback connectors are used to insure reliability.
Electrical surge suppressers 6 suppressers
are provided to suppress any inductive coils found in the press
electrical control system. Additional suppressers are listed under
optional equipment.
Control Console push buttons and operators. We use only NEMA 12
rated industrial operators.

Entry
Waddington feeds come with a IP-66-rated (oil, water, and
dust-tight) industrial touch screen. Changing the feed parameters,
such as length, speed, and acceleration, is fast and simple.
Jog
The jog feature allows the press operator or setup person to jog the material through the die. When used in conjunction with jog-to-length feature, the material can be jogged up to stock guides started in the guides, and then continued into the next die station, the jog-to-length software will automatically stop the feed at exactly the proper location. This feature allows for rapid threading of progressive tooling with stock lifters or unsupported areas between die stations.
Electrical /Pneumatic roll open/close operation
For easy stock threading into feed rolls.
Special Tools We provide special tools to help the setup person get
the most from their new feed. T-handle wrenches are provided for
operator mechanical adjustments like pilot release travel,
anti-backlash gear setting and, in some cases, feed passline
adjustment.
Electrical I/O
Registration input for precision location of printed or
prefinished stock.
E-Stop String Input Stops feed.
E-Stop String Output Can be used to stop other equipment.
Index Complete Used to cycle presses or other equipment and can be
tied into die protection systems.
Fault Signals other equipment in event of feed overload or
failure
Load Meter Can be used to detect stock jams and other tooling and
feeding problems.
Pilot release Our air operated pilot release driver can be
interfaced with a variety of electronic Cams, limit and proximity
switches.
Control Console:
The control console (NEMA 12) is wired to J.I.C. standards The
dimensions are approximately 16" x 14" x 8".
Standard color: PRF light gray. The enclosure needs to be mounted.
It should not be mounted to the press.
Documentation and support:
Each feed ships with one set of D-Sized electrical drawings, an installation guide, an operator’s manual with programming instructions, examples and a trouble-shooting guide.
In addition, factory manuals are provided for the positioning system and servo drive.
All systems are followed by our computerized feed tracking database; all major feed components are tracked by serial number. This computerized system allows our service and support staff to provide prompt answers to your servo feed application questions and service requests.

Special Rolls
Matte Chrome Finish on Rolls:
SLC series feeds come standard with smooth rolls. Matte Chrome feeds
rolls are grit blasted and then finished with industrial chrome.
Brand name finishes such as Kroton are also available but are basically the same composition. Chrome plated rolls provide excellent roll wear characteristics and the rougher finish provides improved traction between the rolls and the stock preventing material slippage during high acceleration. Smooth rolls work best with Prepainted materials and are also sometimes used to prevent material marking on some materials.
Matte chrome is used in most general stamping operations
and when increased gripping force is required
