Abstract
Apparatus for affording access to a dark chamber in a housing wherein successive customer films are spliced together has a door with a window which is normally sealed by a pair of sealing devices one of which has a cuff with two normally closed openings for insertion of hands and the other of which has two overlapping curtain panels. The operator inserts the hands into the openings of the cuff and thereupon pushes one or both panels aside to reach into the dark chamber when the need arises. The panels seal the chamber from the outside even if some light penetrates through one or both openings of the cuff, and the openings are filled by the wrists of the operator when the panel or panels are deformed to afford access to a defective film or cassette for film in the dark chamber.
