Moving the drum 1 turn.
The drum spins clockwise(viewing from the right) one complete turn at a low speed.
After the turn of the drum the film is relaxed by releasing the drum vacuum and
after some time the drum vacuum comes back on to suck the film back on the
drum.
Depending on the filmsize we have two different drumpositions for film
relaxation.
24-25-26 inch: film edge at spoiler side is holded by the suctioncaps
27-28 inch: film edge at spoiler is holded by yellow roller.
At the end of this cycle the film is puched back to the drum by means of the
roller. And this in the begin and end position of the film(par 61 and par 62-63-
64-65-66 ) of the feeder parameters.
Par 61 is the drumposition where the rol comes down in the spoiler
Per 62-63-64-65-66 is the drumposition where the rol comes down on the end of
the film.
Par 57-68-69 : see explanation in part ‘The Film Feeder Parameter Settings’.
