McHale Orbital - Care of the Film Roll; Side-Tip Bobbin Adjustment

McHale Orbital Round Bale Wrapper

3. Multiply the resultant figure by 2 (for 4 film layers), 3 (for 6 film layers),
4 (for 8 layers), 5 (for 10 layers), etc.
4. Round up to the next full number if the result contains a fraction of a full number
Example:
 Number of ‘Wrapping ring rotations’ to cover bale: 3.5 = (x)
 Number of rotations to apply 4 layers of film to bale = (3.5 + 0.5) x 2 = 8
Important Notes:
 (x) ‘Wrapping ring rotation’ = both dispensers rotating 360° around the bale
 Bale diameter must not vary by more than 3%. If this is not possible, then the
above test must be carried out on the largest diameter bales to be wrapped.
6.3 Care of the film roll
The film roll should be protected from damage, moisture, and prolonged exposure to
the sun. Do not remove the protective cover until ready for use. Film damage can cause
undesired film performance and affect bale weatherability.
6.4 Side-tip bobbin adjustment
For machines equipped with side-tip the angle and lateral position of the rear bobbin
assembly is adjustable to handle different size bales. There are two angle positions on
the assembly which can be secured with the lock pin at either location A or B. There is
approximately 100 mm of lateral adjustment to allow for bale sizes between 1,250 and
1,450 mm and this equates to the bale radii increasing from 625 mm to 725 mm.
NOTE: Check bale diameter for enough wrapping ring rotations
It is very important to note that bales in excess of 1,300 mm will not have
enough ‘wrapping ring rotations’ if the above exercise has been carried
out on a normal 1,250 mm bale. Therefore, it is important to check the
bale diameter at every change in crop condition or in differing crop row
widths and densities.
ENVIRONMENT: Dangerous health effects of burning plastics
It is vitally important to observe health and safety rules in order to avoid
unnecessary environmental damage or danger to anybody near the
machine. This especially applies to the responsible disposal of plastics.
Never throw away or burn waste net or plastic. Burning plastics is toxic
as they release dioxins and furans. To inhale dioxins or to be exposed to
its fumes can cause deadly results. Respect the environment! Always
take waste materials to a recycling centre.
