Roll Transfer Coating System
The Arnold Machine Roll Transfer Coating System is commonly used for high-volume, smooth-diameter tubular parts that require external coating coverage. The system can apply paint, adhesive, rust preventative, lubricant, or virtually any other solvent or water-based material needing to be applied. The system utilizes an automatic feeding and load/unload that does not require an operator to manually operate.
The machine is Class 1, Division 1 explosion-proof with fully enclosed coating and heating stages designed for 100% transfer efficiency of coating materials. The system can apply up to three different materials with a drying stage between each. The system also includes a preheated stage prior to the first coating station. Finished coated and dried parts are automatically unloaded into a bulk container.
Benefits of Roll Coater Systems
Automated High-Speed Coating
Processes up to 2,880 coated and dried parts per hour with no manual intervention required.
Minimal Adhesive Waste
The system offers upwards of 100% transfer efficiency and ensures minimum adhesive waste.
Reduced Labor
The intuitive design allows for a single operator to run the entire system.
How Roll Coater Systems Work
Here’s how our roll coater system efficiently coats your parts for consistent, automated results:
- Parts Loading: A bulk tote is placed onto a powered dumper. Once the operator clears the safety light curtain, parts are dumped into a hopper and conveyed via a flighted or stepper feeder to a belt conveyor.
- Shaft Loading: Dual-actuated mechanisms place parts onto spindle shafts mounted to an indexing chain conveyor, moving two parts at a time.
- Temperature Increase: Parts travel through an electric oven loop to raise their temperature before coating.
- Primer Application: A rotating applicator wheel applies Chemlok primer to the part’s outer surface.
- Top Coat Application: After another oven loop, parts receive a top coat via a second applicator wheel.
- Final Coating & Part Monitoring: A third loop allows for a final material coating. Dual sensors confirm part rotation; if rotation is not detected, the part is flagged for diversion.
- Cooling & Unload: Parts cool to 125-130°F before exiting the spindle and sliding down a gravity chute. Defective parts are removed via a pneumatic diverter.
- Part Counting & Collection: Finished parts are counted by a laser sensor and collected into a tote. When full, the operator swaps the tote manually.

COMMON APPLICATIONS
Roll transfer coating systems are ideal for cylindrical parts requiring uniform external coverage. These include:
- Suspension bushings
- Tubular metal fasteners
- Bushings, pins, or sleeves used in chassis, drivetrain, or stamped assemblies
- Parts requiring rubber-to-metal adhesive coatings
Their ability to handle small, lightweight parts (under 2 lbs) at high throughput makes them especially effective for Tier 1 automotive suppliers and OEM production lines.
