The film is loaded onto the unwind shaft with the
seal gap edge facing the inside. The film is then
routed around the outside of a spring-loaded roller.
This roller maintains film tension by controlling
the amount of braking applied to the unwind shaft.
The seal gap edge of the film is then guided over
the end of the air injection tube. The air injectio
tube extends through the seal section, and past the
outfeed nip rollers. See Figures 2.
