ABSTRACT:
A method and an apparatus for assembling photographic film cassettes each comprising a spool assembly and a pair of shell halves. A plurality of pallets are stepwise conveyed on a pallet conveyer. Each pallet has a spool holder, an intermediate holder and a shell holder. Parts of the spool assembly are sequentially fed to the spool holder and are assembled into the spool assembly at the spool holder. The spool assembly is transferred from the spool holder to the intermediate holder to be turned from a vertical into a horizontal orientation. Thereafter, the spool assembly and other parts of the photographic film cassette are sequentially fed to the shell holder and are assembled into the photographic film cassette at the shell holder.
