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.

How Roll Coater Systems Work
Here’s how our roll coater system efficiently coats your parts for consistent results:
Parts Loading: An operator places a bulk parts tote onto a powered tote dumper. After stepping behind a safety light curtain, the operator activates the dumper. Parts funnel into a bulk hopper and are transferred upward via a flighted conveyor or stepper feeder onto a belt conveyor. The belt positions the parts for loading onto spindle shafts at a continuous programmable speed.
Shaft Loading: Two separate actuated mechanisms secure parts to shafts located on an indexing chain conveyor. The conveyor moves two parts simultaneously on opposing sides of the chain.
Coating Process:
- Temperature Increase: Parts travel through a series of loops in an oven to raise their temperature.
- Primer Application: Parts pass over a spinning applicator wheel that applies the Chemlok primer.
- Top Coat Application: Parts move through another loop and then a second applicator wheel for a Chemlok top coat, followed by a final loop before receiving their ultimate coating.
- Part Rotation Monitoring: Throughout the coating process, two sensors monitor part rotation and ensure consistent application. These sensors can sometimes detect glare from coated parts, an issue that AMI will work to resolve.
Cooling and Unload: Coated parts travel along a conveyor to cool down to a temperature of 125-130°F. Formed sheet metal guides parts to the outside of the spindle and onto a gravity chute. A pneumatic diverter removes any defective parts (those where one of the sensors did not detect rotation during coating).
Final Steps: Acceptable coated parts drop into a large tote and are counted by a Keyence LRZ laser sensor. Two large totes (one empty, one full) are placed on a gravity roll conveyor. When the HMI signals that a tote is full, the operator pushes the empty tote into position and replaces the full tote with an empty one.

Common Applications
Roll coater systems offer a reliable solution for coating cylindrical aluminum or steel parts in various manufacturing settings.
These systems are ideal for components with a flat or straight surface, ensuring an even coating result. Smaller parts weighing under 2 lbs are particularly well-suited for this equipment.
