- providing a plurality of brim formers arranged circumferentially around a central axis,
- rotating each brim former about an associated former axis that is spaced radially from the central axis,
- feeding the container between the plurality of brim formers with an unrolled brim of the container in contact with each of the brim formers,
- advancing the container along each of the brim formers as each brim former is rotated about each former axis,
- heating a first portion of each brim former with hot air to heat the brim of the container as the container is advanced along each brim former,
- cooling a second portion of each brim former that is downstream of the first portion to cool the brim of the container, and
- applying pressure on the brim of the container with each of the brim formers as the container is advanced along the first portion and the second portion to provide a rolled brim for the container.

- heating a first portion of each brim former with hot air to heat the brim of the container as the container is advanced along the first portion of each brim former,
- cooling a second portion of each brim former downstream of the first portion with a cool liquid to cool the brim of the container, and
- insulating between the first and second portions by blocking flow of the hot air along the threaded surface from the first portion to the second portion.
