PRF-4800HD
- HD Feed feature 1 or 2 servo motors
- 2 or 4 four or six inch diameter rolls
- widths to 60 inches
- High Speed
- High Accuracy
-
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.
