Abstract

The machine forms the profile, on a sheet-metal pot-shaped body, with a coaxial channel-section open to the outside. It has a rotary embossing tool running against the outside of the body. The tool is an internal cylinder (7), rotating on an internal eccentric (11). The latter in turn rotates on its axis (15), which is on an external driving eccentric (14) rotating on the body axis (2). Relative movement of the eccentrices generates a transverse feed movement.
