ABSTRACT:
A method and apparatus are disclosed for forming an outwardly projecting bead in the sidewall of a cylindrical object. The apparatus includes an inner forming member and an outer forming member having a leading forming surface, a trailing support surface, and a recess therebetween. The method includes forcing the sidewall of the container in a radially outward direction by applying a force to the inside of the sidewall, and limiting the resulting projection to a desired sidewall region to form an outwardly projecting bead in the container sidewall.
