Edge wrapping adjustment

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.
A switching angle [3] (Figure 33) is installed in the right-hand
shuttle, which is attached by two screws in a unit with a set of
holes. Four different installation positions are available.
By displacing the angle towards the variable diameter disc, the
variable diameter disc is pressed closer together for the area of
the edge wrappings. The effective diameter increases and more
edge wrappings are applied to the edge of the bale. Setting:
Displace switching angle (3) towards the variable diameter
disk: more end windings on the edge of the bale.
Or:
Displace switching angle (3) towards the machine centre:
less end windings on the edge of the bale.
