A convertible flange insertion machine for the insertion of a pair of internally threaded flanges into a drum head of a shipping container is disclosed. The machine includes a pair of continuously moving drum head conveyor chai ns running along conveyor supports and between a pair of tooling dies that upon compression insert flanges into the drum head. A pair of flange conveyors ru n along side the drum head conveyor and include a pair of side rails with two lips for guiding the lips of flanges according to two different flange styles. The flange conveyors terminate at a lateral transfer mechanism. One lateral transfer mechanism includes an indexer with two pawls that sequentially indexes flang es in a two step procedure over a pair of spring loaded stops and into the receivi ng pocket of a tooling block. The tooling block places the flanges over the tooling die where a release assembly forces the flanges out of the tooling block and ont o the die. Another lateral transfer mechanism includes an indexer that directly indexes flanges laterally off a floor to be dropped into the die, and the indexer includes a flange engaging portion that holds the trailing edge of the flange to preven t the flange from tipping while it drops into the die. The drum head is placed ove r the flanges and the die portions compress, which lowers the conveyor supports an d causes the drum head to come to rest on the lower die portion, and insert th e flanges into the drum head. The machine is operable in both a one-step and t wo- step flange insertion procedure.
