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 chains 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 run 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 flanges in a two step procedure over a pair of spring loaded stops and into the receiving 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 onto the die. Another lateral transfer mechanism includ es 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 prevent the flange from tipping while it drops into the die. The drum head is placed over the flanges and the die portions compress, which lowers the conveyor supports and causes the drum head to come to rest on the lower die portion, and insert the flanges into the drum head. The machine is operable in both a one-step and two-step flange insertion procedure.
