Pre-settings for chamber film wrapping:
• The tension lever (12) must not touch the wrapping material roll (1). To do this, the tension
lever (12) must be locked,
refer to page 152 .
• The conical roller (3) must be released to ensure that it rotates during chamber film
wrapping,
refer to page 153 .
ü The machine is shut down and safeguarded, refer to page 25 .
ü
The roll holder has been swivelled forwards.
ü
The conical roller (3) has been locked or released depending on the set net or chamber film
wrapping,
refer to page 153 .
ü The tension lever (12) has been locked or released depending on the set net or chamber
film wrapping,
refer to page 152 .
ü
The wrapping material brake has been set to net or chamber film wrapping, refer to
page 151 .
„ Unwind a section of the wrapping material (11) from the wrapping material roll (1) and guide
it over the deflection roll (2) and under the deflection roll on the cross tube (10).
„ Place the wrapping material (11) over the conical roller (3).
„
Place the wrapping material (11) under the spreading roll (4) on the retaining sheet (6).
„
Using the supplied feed plate (7), push the wrapping material (11) between the retaining
sheet (6) and the synthetic cloth (5).
„
Ensure that the wrapping material (11) is spread over an area (8) of at least 2 feed strips.

8.13.3 Notes on operation
• When chamber film wrapping starts, it is necessary to continue collecting crops until the film
is caught by the round bale and the film roll is turning.
• If possible, for initial operation, use a complete net roll first and tie the round bales with net.
This procedure can be used to remove any sharp edges or paint residue beforehand.
• KRONE recommends not to use chamber film wrapping for straw bales. There is a risk of
condensation forming, resulting in mould.
• Tie the round bale with the appropriate film tension, refer to page 86 .
• KRONE recommends 3.5-4 film layers to ensure optimum chamber film wrapping, refer to
page 119 . The dryer the crops, the more film layers will be required.
• A machine with chamber film wrapping can still tie round bales with net. In doing so, ensure
that the the conical roller and the tension lever are set differently.
• Setting the locking of the conical roller: refer to page 153
• Locking/releasing tension lever: refer to page 152
8.13.4 Checking the tension of the inserted film
The round bale must be tied with the appropriate film tension. KRONE recommends a pre-
tension of 5-15%. You can check whether this pre-tension of 5-15% has been obtained as
follows.
