Knoll Multibaler 1220

Loose material should be loaded from above into the bunker of the machine. This can be done using a tractor unit + front loader, crane or wheel loader. The feed bunker can also be loaded from the ground or in combination with a silage wagon using the optional ''KNOLL Drop bunker''.


The bunker is equipped with movable side plates, which reduces the height for loading.


After loading, the material is transported to the bale chamber fully automatically by means of a bottom chain


The bottom chain automatically pauses when too much material is fed in and thus adjusts itself to the type of material.


Shortly before the bale chamber, two dosing rollers ensure a regular distribution and flow of material towards the bale chamber.

The material is compacted in the bale chamber resulting in a volume reduction of up to 50-70%. This depends on the type of crop or material and the dry matter content.


The bale chamber of the MultiBaler 1220 is fitted with two heavy-duty drive chains with 107 tight bars between them. This system together ensures a closed bale chamber.


Each tight bar exerts pressure and traction on the material during baling, ensuring shape-retaining bales.


This special chain system handles many short-cut materials and shapes them into a perfectly shaped bale.


The "horizontal flow" of material through this machine also makes it possible to sometimes to handle little bit longer material as well.

After compacting the material into a round bale, it is important that the bale is tied properly with net or mantelfilm before it leaves the bale chamber.


Secure film or net binding ensures perfectly shaped bales. The MultiBaler 1220 owner can choose whether to use net or sheeting for this process.


Changing between net or film is simply a matter of changing a setting in the machine's computer and installing the correct roll.


The ''film & film'' principle is based on a number of layers of mantelfilm in combination with wrapping film that is tied around the bale and guarantees a high press density and good bale shape. This principle also provides a better oxygen barrier, resulting in a better end product with a higher yield.

KNOLL MultiBalers are equipped with an integrated return system for recycling "crumb losses".


During the processing of (short) materials, small losses always occur. With the help of the return system, no product is lost.


The return system consists of a construction that is located under the entire length of the press chamber and wrapper. From here, the losses are transported to the front of the machine by means of a bottom chain. The vertical return auger is located at the front. This upright system is equipped with two augers that move the material upwards and "recycle" it back into the infeed bunker.


Material losses are reduced to a minimum by the presence of a return system.

KNOLL MultiBalers are equipped with an ingenious wrapping system. When the bale is ready in the bale chamber, it is automatically transferred to the wrapper. With the MultiBaler 1220, both the return system and the wrapping system are combined, ensuring an easy and efficient movement of the bale. This also ensures a very clean transfer and at the same time effective handling of the crumb losses.


The wrapper is equipped with a wrapping arm with two film stretchers for 750 mm film rolls and two cut-and-hold cutting systems for the wrapping film.


During the bale wrapping the process is monitored by the film control system. When a film roll is empty or when it breaks, the system reacts automatically.
