Inside the UV Bottom Rim Coater
This video provides a rare inside view of the UV Bottom Rim Coater, where Brite Cans undergo a critical process after passing through the Washer and Dry-Off Oven. This view is unique because UV light is typically dangerous to the naked eye.
Cans are lifted by a vacuum transfer device, which grips the cans from the top, exposing the bottom for coating. The cans then pass over a roller that applies the Bottom Rim Coating, after which the coating is cured using UV or UV-LED light. Once coated, the vacuum transfer lowers the cans back onto a mechanical conveyor, and they exit the UV Bottom Rim Coater.
Bottom Rim Coating plays an essential role in the can manufacturing process by enhancing the mobility of cans. This coating allows the cans to slide more easily along their bottom rims.
This is especially important at the Decorator Infeed, where cans are fed from the upper level and pass through a conveyance device called an Air Doubling Box. The cans are then arranged in single file and fed into the Decorator. At high production speeds, smooth movement is crucial, and the lack of a bottom rim coating can cause the infeed process to struggle.
The second key reason for applying Bottom Rim Coating is during the Filling Process. Once cans are filled with product, they become heavier, making bottom mobility critical. Without a proper coating, cans may tip over, causing backups and jams in the filler line, disrupting the production flow.
