In this video, we're going to talk about the body maker and the trimmer. While each can line typically uses only one cupper, multiple body maker and trimmer combinations are necessary to keep the production line running smoothly.

Cups enter the body maker from cuff conveying on the second level, where they are gravity-fed into the machine. Inside the body maker, two main processes occur:

The cup is drawn into the shape of a can.

This process involves three ironing rings that thin the walls of the can, making it both thinner and taller.


At the end of the body maker's stroke, the can strikes the domer, which forms the dome shape at the bottom of the can. After leaving the body maker, the cans will have thin walls and a jagged top edge.

Cans are then conveyed into the trimmer, again using gravity. The primary function of the trimmer is to remove the jagged top edge of each can. Typically, a small amount of material is trimmed from the top to ensure a clean finish. Cans exiting the trimmer will have a smooth, straight cut edge.

Each can features a few markings at the bottom of the dome, including the body maker ID. This ID helps identify the specific body maker, assisting in troubleshooting should any problems arise in the production process.
