Unload process.
Description of the different parts.
The drum: The goal is to transport an exposed medium, like a
photosensitive film, from the drum to a developing machine or an unload
tray. During the expose the medium is held on the drum by a high vacuum.
Entrance vacuum: The high vacuum is generated by a vacuum pump and
via a flexible tube connected to the drum. The connection at drum side is
central to the drum and made out a non-friction coupling.
Exposed medium.
Holes in drum: At the beginning of the film a special hole pattern is made
in the drum to keep the film fixed on the drum during spinning. At every
half inch such a hole is made in the drum. Just after the mechanical bend of
the drum a second row of holes are made in the drum. The purpose of this
is to firmly attach the film on the drum and to make sure that the film takes
the same shape of the drum with no deformation.
Holes in the drum: At the end of the film holes appear in the drum every
half inch. These holes are connected with the first holes through a vacuum
channel. So there is suction force on the film around the drum.
Upper roll. Holding the film during unloading.
Unload table: This table puts the film on the transport mechanism.
Transport mechanism: This brings the film towards an unload tray or
developing machine.
Unload bottom plate: During load the film hits this plate. Plate is made
from a special material so that no scratches are made on the film.
