Wrapper 5100
fig.16 – Film passage
Note: The filmstretcher is provided with a rolls
block system, which prevent their rotation
when the film isn’t in tension.
The function of this system is to avoid the
accidental unwinding of the reel during
transport.
DANGER
When machine is trailed on road it is
obligatory to take the reel away from
filmstretcher.
4.5 FILM OVERLAPPING
The bale wrap happens through combination of
two movements: first movement along vertical
axis rotation, which has given from the cradle, and
the other along horizontal axis rotation, which has
given from rolls rotation.
The ratio between wrapped surface of the bale for
every cradle tour and the stretched film height has
called film overlapping level (fig.17).
The overlapping level has determined by gear
ratio between cradle and rolls rotation.
The film overlapping has to be of 50%, i.e. the film
has to overlap for its half on the previous tour.
fig.17 – Film overlapping
The wrapped surface of the bale for every cradle
tour has to be set up about the used film height:
-
with a reel of 750 mm you get a film, that after
stretching, has a height of about 600 mm,
therefore wrapped surface of the bale for
every cradle tour has to be of 300 mm every
tour;
- with a reel of 500 mm the stretched film has a
height of about 400 mm and the wrapped
surface of the bale for every cradle tour has to
be of 200 mm every tour.
The statement of wrapped surface of the bale for
every cradle has set up by substitution of the
pinion in cradle case (fig. 18).
You have to proceed as follows:
1- To remove the protective case
2- To relax the stretcher (C)
3- To replace the pinion (A) with the needed
one (B)
4- To adjust the chain way: with the pinion
Z24 has to pass it over the counter (D),
while with pinion Z16 has to pass under it.
5- To tighten the chain and fix the pinion (C).
6- To reinstall protective case.
