5.1.3. Setting the edge clearances

In order to limit the twine wrapping on the ends of the roll bale,
the edge clearance retainers [1] are adjustable (the right side of
the baler is shown in fig 30 and fig. 31, but the same applies to
the left side):With very dry and brittle crops it is better if the
retainers are located more towards the middle of the baler.

5.1.4. Setting the distance between twine wrappings

The distance between the wrappings is given by the diameter
used for the variable diameter disc [9] (fig. 27). The smaller the
effective diameter of the disc, the greater the distance between
the wrappings.
On the far right-hand edge of the cross-support is a lever [2] (fig.
29 and fig. 31), which is used to set the distance between the
wrappings.
Setting
Position 1 .............................................greatest winding distance
Position 7............................................. smallest winding distance

5.1.5. Setting the edge wrappings

In order to ensure that the high density bales remain well
compressed, the twine wrappings are automatically laid closer
together near the edge of bales.
In order to achieve this, the right-hand shuttle [4] presses the
variable diameter disc closer together when reaching the end
zone. The working diameter of the variable diameter disc
increases and the distance between wrappings is reduced
towards the edges.
An adjustable arm [3] (fig. 29) is installed in the right-hand
shuttle, which is attached by two screws in a unit with a set of
holes. There are four different installation settings available.
Setting
Switching angle (3) towards the variator disk → more end
windings on the edge of the bale
Switching angle (3) towards the machine centre → less end
windings on the edge of the bale
