One of the most expensive methods of film-cleaning, that of cleaning by hand on a drum, is considered to be the best for achieving the cleanest possible film. In building the drum described in this paper every effort was made to make the operation as efficient as possible. The drum is motor-driven, forward and reverse, has a solenoid brake, and the drive and the brake can be disengaged for manual operation.
