Chain-on-Edge Conveyors
Achieve faster throughput and superior coverage for your complex parts. Arnold Machine Chain-on-Edge (CoE) conveyors combine speed and precision for exceptional coating quality.
We build our paint booth conveyor systems to withstand the rigorous demands of high-volume production environments. This ensures your coating operations experience minimal downtime and deliver consistent results.
Benefits of Chain-On-Edge Conveyors
Efficient Coating Application
Servo-controlled precision and targeted spraying reduce waste and ensure a flawless, consistent finish.
Optimized Adhesive Dispensing
Precise flow meters ensure consistent adhesive application and prevent quality issues.
Easier Loading/Unloading
Loading and unloading processes are synchronized with stop cycles to simplify operation and boost efficiency.

How Chain-on-Edge Conveyors Work
Arnold Machine Chain-on-Edge cleaning lines streamline the coating process by transporting parts through a series of stations designed for loading, pre-heating, spray application, drying, and cooling. We designed the system to utilize and apply two (2) coating materials throughout the process (solvent or water-based adhesive primer and top coat). The system can also be configured for a single-coat adhesive.
Here’s a detailed look at how they work:
- Load Station: The operator manually loads the appropriate fixtures and parts onto the spindles presented in the load area. This area will have 6' of accessible fixtures for loading and an overhead light for easy visualization. The load station includes an operator work fan.
- Pre-Heat Station: For the primer to adhere to the part, it must be preheated to a predetermined temperature. The pre-heat station in the oven consists of forty-eight (48) spindles to maximize cycle time and oven efficiency. Once the parts have reached temperature in the pre-heat station, they will be conveyed to the primer spray station.
- Primer Spray Station: Parts will enter the spray booth, and the spindle will be engaged with a variable speed belt drive system for part rotation. Two (2) Krautzberger spray guns mounted to FANUC Paint Mate robots are utilized to apply the primer to the part.
The Spray Station controls airflow for maximum transfer efficiency and accommodates ease of cleanup and maintenance.
A Keyence flow sensor will verify that a specific amount of primer has been sprayed from the spray gun between the primer spray station and the primer dry oven. If it does not detect the primer flow, it won’t apply a top coat to the part in the top coat station. The primer pressure pot will be located in the material storage cabinet and provided with all gun connections to the pot.
4. Primer Dry Station: After parts exit the primer spray station, they enter the oven for a series of cycles in the primer dry station. This area will allow the primer to dry further before applying the top coat. There will be eight (8) spindles in this station.
Common Applications
Chain-on-edge conveyors are commonly used to coat straight or profiled cylindrical substrates that require inside or outside diameter coverage.
They efficiently coat multiple faces of a part when needed. Typically, they are used with aluminum or steel substrates ranging in diameter from 1 inch to 5 inches and up to 6 inches tall.
Our CoE conveyors are ideal for large production runs with consistent part sizes and shapes. These systems automate the painting process and reduce the need for manual involvement.
This leads to excellent process control and ensures each part is painted similarly. However, it is important to consider part size limitations and variations when choosing this system.
