In order to wrap a square bale or a cube,
it needs to rotate the bale via two axis.
Different to other wrapping systems the
ROTOWRAP machines do these two rotations
at the same time, which increases
the throughput vastly.
The rotation of the bale on the oscillation
rollers is smooth, exact and controlled and
even with loose or weak bales it is possible
without loss.
The wrapping machine is placed in line
directly behind the baler. When the bale
is pushed by the baler via a ramp forward far enough, the bale is recognizes and the
automatic cycle begins.
The transportsystem
brings the bale into the wrapperunit
between the oscillation rollers which lift
the bale into the wrapping position and
wrapping starts. The rollers rotates the
bale around its horizontal axle and the
wrapping arm with 2 film rolls of 750 mm
wide film is rotating around the bale.
These
rotations are exact and relative to each
other to get the correct amount of film
on every place of the bale. According to
special circumstances or customer needs, there are plenty of variations to adjust
overlap and number of layers to bring as
much film as necessary and as less film as
possible to the bale.
When the wrapping is finished the film is
cut by a cut & tie system prepared for the
next bale.
This system saves film. The next
step brings the machine back to the conveyor
system which transports the bale to
the collecting conveyor.
From here it can
be taken away by forklift.
