Rotomat Automatic Saws

The saw’s rotating drum is loaded with split metre-long pieces. The drum’s incline causes the wood to slip automatically to the adjustable base, where the internal saw blade cuts it to size. The drum advances to the next insertion channel as the sawing takes place. The sawed-off piece falls out onto the belt conveyor and is carried off. The remaining piece rests on the saw blade and is carried along to the 9 o’clock position, where it falls back to the base. This process repeats itself until the channel is empty.

When all channels are loaded, theoretical performance levels of up to 18 m3/h can be reached (depending on the model and cutting length). The belt conveyor, part of the standard model, ensures quick removal of the wood, with dropping heights of over 3 m. The cutting length of the wood can be set between 20-50 cm, depending on the model.

You’ll enable quick sawing with high performance
and the utmost safety.
Drum saws are the best way to process
enormous quantities of firewood.
