ABSTRACT:
The invention provides a process and apparatus for forming an outwardly rolled lip on a cylindrical container body. The apparatus of the invention includes a mandrel having a cylindrical shaped portion and a lip forming annular cavity positioned coaxially with, and axially spaced from the cylindrical portion of the mandrel. The annular cavity has a generally semi-circular cross-section including an open mouth and a closed bottom extending outwardly of the mandrel. The mandrel additionally includes a radially tapered portion between the cylindrical portion and the lip forming die. The radially tapered portion tapers radially outwardly in the direction towards the lip forming die. An axial forcing means forces a cylindrical container body axially along the mandrel towards the lip forming die to thereby stretch the open end before the end is forced into the cavity and rolled outwardly.
