Two or more belts
Parallel conveying surfaces create the circulation path.
19Engineered solution
Recirculating conveyors
Manufacturing lines need consistent product flow to maximize throughput. Recirculating conveyors move products quickly and reliably while helping avoid backups, redirections and shutdowns.
20What is a recirculating conveyor?
Controlled space between one process and the next.
A recirculating conveyor is machinery that helps products move through a manufacturing line. It creates an organized buffer so production can continue when upstream and downstream processes run at different rates.
Powered movement
A motor drives the belts at the required line rate.
Guides and dividers
Side guides and dividers control how parts circulate and exit.
21System types
Recirculating tables and accumulation conveyors.
Both manage uneven line rates, but the required buffer, outfeed and product determine the configuration.
Recirculating tables
Create space for product to accumulate and control its flow into the next manufacturing process.
- Low-friction conveying surface
- Fabric or modular belt
- Plastic chain option
- Continuous circulation or operator release
Accumulation conveyors
Contain overflow and buffer items until a downstream machine or operator is ready, providing automated control along the line.
- Smooths fluctuations in line rate
- Singulates and controls outfeed
- Merges multiple lines into one
- Fabric, urethane, modular belt or plastic chain
More buffer in the same frame.
Multiple belts can be arranged within one frame to provide more accumulation space than a traditional inline conveyor.
22How recirculating tables work
Opposing belt directions keep product available.
Two or more belts move in opposite directions. Products can circulate continuously until they are released in a single line to the next process, or accumulate until an employee is ready to handle them.
Infeed→Circulate↔Single-file outfeed
A basic recirculating table can operate unattended without electronic controls.
23Problems solved
Keep a temporary delay from stopping the line.
When one point backs up, a recirculating table creates controlled accumulation instead of forcing upstream production to stop or redirect product.
Prevent backups
Buffer product when a downstream process slows or pauses.
Protect upstream output
Continue producing without immediately stopping or rerouting product.
Handle delicate items
Minimize back pressure to reduce the likelihood of damage and loss.
Control the release
Organize accumulated parts for a predictable single-file outfeed.
24How to use a recirculating table
Load. Orient. Singulate.
Custom features vary, but the core process stays consistent: parts enter, organize into one line and leave on a controlled conveyor path.
Load and accumulate
An employee manually dumps parts onto a two-belt recirculating conveyor. A guide gathers them and directs them toward an opening.
Align at the opening
A UHMW block ensures the parts enter single-file in the correct orientation, knocking over any parts standing on their side.
Release one at a time
A pneumatic V-block moves each part into position so it can transfer to the next machine.
This three-step workflow is retained as a historical source example, not represented as a Roarer project.

27Frequently asked questions
Recirculating tables.
Selection, belt materials, integration and project coverage.
What sets recirculating conveyors apart?
Every conveyor type has a practical use. Recirculating conveyors are especially useful where automation is needed to move parts smoothly through a manufacturing line while creating controlled buffer space.
Can recirculating tables handle large parts?
Yes. A custom table can be sized and configured to handle large parts, subject to product dimensions, weight, stability and the required buffer capacity.
What belt types work with recirculating tables?
Use low-friction conveying surfaces so products move as intended. Typical options are low-friction fabric or modular belts and plastic chain; accumulation conveyors may also use urethane.
Can they be combined with other conveyors?
Yes. Recirculating conveyors can operate as one part of an integrated manufacturing line, receiving product from upstream equipment and feeding downstream machinery at a controlled rate.
What warranty applies?
Warranty coverage depends on the selected components, operating conditions and agreed project scope. Roarer documents the applicable coverage in the project proposal rather than applying a universal term.
How is a custom recirculating table created?
The process can include concept and needs analysis, layout and CAD modelling, mechanical design, controls engineering, factory and site acceptance testing, installation, training, maintenance planning, and replacement or spare-parts support.
