air is replaced.
The blower and heating element power is controlled by a
switch on the control panel, and a thermostat in the dryer section regulates
the temperature.
f. Drainage system.
The drain used for the Versamat must be a 4-inch,
open drain capable of handling 4 gallons per minute during normal operation, or
8 gallons per minute when draining the tanks.
g. Roller transport system (fig 2-6). The transport system consists of a
film detector assembly, seven racks, eight crossovers, a squeegee assembly, and
two crossovers, transport rollers, and turnaround in the dryer.
Each roller
rack consists of a series of chain-driven rollers mounted in a staggered path.
The rotation of the rollers moves the film through the processor. As the film
reaches the bottom of the rack, a turnaround assembly turns the film 180. When
the film reaches the top of the rack, a crossover assembly conveys the film to
the next rack.
This process continues through each rack assembly until the
film is transported to the dryer assembly.
In order to transport film in
continuous lengths, the surface speed of the rollers is slightly increased in
certain locations in the processor.
This enables the transport system to
prevent any slack that could be built up due to normal film swelling. Slight
increases of speed occur in the following locations:
