A thin walled body such as a container is gripped at a holding station and tooling is engaged to deform the wall of the body at a predetermined zone. The predetermined wall zone is co-aligned with the tooling by means of co-ordinated movement of the tooling (typically by means of rotation about a tooling axis) prior to engagement with the wall zone.
