When shaping a film cartridge having a hollow cylindrical shell and caps mounted on ends of the shell, a shell plate is brought into abutment with a mandrel having a perfectly circular cross section and bent around the mandrel by a bending roller. A cap is mounted on an end of the hollow cylindrical shell while it is on the mandrel, and the cap is clinched to the hollow shell while the cap and the hollow shell are grasped from the outside.
