Overview
New London Engineering powered curve conveyors change product direction while maintaining product orientation. The family includes V-belt driven live roller curves, Models 630 (30°), 645 (45°) and 690 (90°), in widths from 12" to 36", and Medium to Heavy Duty Belt Curves, flat-top belt curves up to 48" wide in arcs from 15° to 180° at speeds up to 400 FPM. PRI supplies New London Engineering powered curves alongside the rest of the NLE line.
Key Features
- V-belt driven live rollers
- On the 630, 645 and 690, V-belt driven live roller spurs are used to merge product lines.
- Straight or tapered rollers
- Each V-belt curve angle is offered with straight rollers or with tapered and straight rollers; the 30° tapered version is Model 631.
- Flat-top belt curves
- On the belt curves, all components sit below the belt's surface, so products wider than the belt will orientate through the curve.
- Positive orientation
- Belt curves are chosen over roller curves where positive orientation is critical, such as baggage handling or printing operations.
- Speeds to 400 FPM
- Belt curves run at speeds up to 400 FPM. V-belt roller curves run at a 60 FPM standard speed.
- Multiple surface options
- Several curve angles and multiple surface options are available.

Applications & Benefits
- Merging product lines: V-belt driven live roller curves merge product lines.
- Turning conveyor lines: 30°, 45° and 90° roller curves change product direction while maintaining orientation.
- Baggage handling: Belt curves are used where positive orientation is critical.
- Printing operations: NLE names printing as a belt curve application where orientation matters.
How to Choose the Right New London Engineering Powered Curve
- Set the turn: 30°, 45° or 90° for V-belt roller curves, or an arc from 15° to 180° for a belt curve.
- Check the width: 12" to 36" for roller curves, up to 48" for belt curves.
- Where positive orientation is critical, or products are wider than the belt, choose a belt curve.
- Match the speed to the line: 60 FPM standard on V-belt curves, up to 400 FPM on belt curves.
- For roller curves, choose straight rollers or tapered and straight rollers.
Why New London Engineering Powered Curves Are Trusted
- Quality conveyors since 1948: New London Engineering of New London, Wisconsin has built conveyors since 1948 and describes its line as American made and American engineered.
- Orientation held through the turn: NLE powered curves change product direction while maintaining product orientation.
- Clean belt surface: On NLE belt curves, all components sit below the belt's surface.
