A device forms a radial flange on a bottom opening of a conate member having a longitudinal axis. The device has a die for receiving the conate member with the bottom opening extending from an open end of the die, a seal-forming cone having at least two radially-extendable sections and being removably located in the open end of the die, inside the conate member, and a handle, axially movable in the cone to extend the movable sections. |
