Mechanical Features:

• Four-inch diameter Upper four inch diameter lower smooth steel finish rolls Our special low inertia roll design is proven performer in thousands of applications.  Also available in 4 inch upper and 4" lower versions.

• Heavy duty dowel-pinned frame We start with high-quality precision ground steel plate. All precision bores are machined in sets and, after assembly and alignment, the frame is dowel-pinned. This insures long-term alignment and feeding accuracy, and has none of the stability problems associated with cast feed frames. The steel is finished with black oxide.

• Permanently lubricated anti-friction bearings Long life back-to-back sets.

• Anti-Backlash gears between top and bottom rolls Provides the lowest inertia solution to the problem of increasing stock-gripping force and eliminating backlash between the upper and lower 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.

• High-speed air pilot release or mechanical 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. Customers routinely use them for applications as high as 300 SPM. Waddington offers many types of mechanical pilot release mechanisms depending on press stroke length and speed. We also offer servo-driven pilot release for applications that involve very high speeds and/or no mechanical access to the press crank shaft.

Electrical Features:

• Brushless low-inertia Servo Motor With high temperature windings and internal thermal protector

• Close loop brushless resolver feedback Provides the most shock-proof absolute position feedback available. Only Waddington feeds feature resolvers that are directly coupled to the bottom feed roll. Unlike systems that have the position feedback device mounted on the back of the motor, this arrangement yields the best servo- positioning performance.

• Following error output Stops press or other equipment in event of stock jam or feed malfunction.

• RS-232 interface For connection to remote computers or Data Instruments’ Spectrum, ProCam 1500, SmartPak, DiPro 1500, and selected Link Systems for total press control integration.

• Military style connectors Only the highest quality motor and feedback connectors are used to insure reliability.

• Liquitight Used on motor cables and remote push button stations, this protects cables from most shop hazards. Unlike some feeds where the lowest cost is the only object, we provide steel armored cable on all leads.

• Electrical surge suppressers 14 suppressers are provided to suppress any inductive coils found in the press electrical control system. Additional suppressers are available.

Control Console push buttons and operators. We use only NEMA 12 rated industrial operators.

• Power "ON"                         (push button)
• Emergency "STOP"                 (palm button)
• Index                                          (push button)
• Manual/Automatic/Jog-to-length (selector)
• Feed rolls open /closed / auto (selector)

 Productivity Features

• Data Entry Keypad Waddington feeds come with a NEMA 4-rated (oil, water, and dust-tight) industrial keypad. It features a 40 x 2-line LCD display and full alpha-numeric entry and display. Changing the feed parameters, such as length, speed, and acceleration, is fast and simple.
• Portable "SETUP" Push-button Station Jog Fwd / Jog Rev / JTL
• A standard feature on Waddington feeds, the jog forward and reverse buttons are mounted in a 2 PB hand-held box and connected to the main electrical enclosure or operator station by a coil cord. There is also a storage pocket that can be mounted in a convenient location.
• 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

• 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. This output is used in conjunction with the software settable index complete window.
• Early index Complete (optional) Used to start other equipment such as hydraulic presses. This output can start other equipment before the feed cycle is finished, and can decrease total cycle time when the feed is used with hydraulic presses.
• 2 Feed to sensor inputs Allows the feed system to position the material based on a registration mark or previously stamped feature on the strip.
• Fault Signals other equipment in event of feed overload or failure
• Following error Can be used to detect stock jams and other tooling and feeding problems
• Current monitor Can be used with load meters to monitor the amount of power required to do a particular job and as a troubleshooting tool in cases of binding and material alignment problems.
• Pilot release Our new solid state 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 enclosure is free standing type. The dimensions are approximately 24" x 24" x 12". Standard color: PRF light tan. The enclosure sits on a set of legs and the slant front push button station is located on the top of the cabinet.

• Remote push button station

The push button station can also be remote mounted from the main feed enclosure. For customized installations and applications where die protection, electronic Cam switch, and programmable pattern options are ordered, larger push-button stations are utilized.

• 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.
