A saw with a frame saw
The frame saw is used for processing debarked and non-barked cutouts with a maximum diameter of 65 cm and a length of usually 2.5 - 6 m, the technology can also be adapted for cutting cutouts up to 12 m long.
Depending on the technology used, the input raw material and the composition of the lumber produced, the annual shift output of a frame sawmill is in the range of 15 – 45 thousand m3 of cut material. Own lines are always configured according to customer requirements and can be equipped with a whole range of technological nodes. The cutouts are loaded onto a transverse chain stock conveyor with the help of a front loader. Separation of stock into individual cutouts and subsequent transport of the cutout to the frame saw takes place automatically.
The cutout then goes through the first frame saw, where it is cut into a prism, side lumber and landscape (waste). This is followed by a passage through a second machine - a second frame saw or circular sweep saw - where the prism is cut into center and side lumber and landscape (waste).
The side lumber from both machines is then trimmed and plastered. Scraps and other lumpy waste is processed into wood chips, which can then be sorted for paper processing.
The sawdust is vacuumed or mechanically removed by a system of vibrating, belt or elevating conveyors.
