Other requirements to sawn timber quality are specified depending on the purpose of further use of the products.

The following equipment is used in sawn goods production process:

  • Debarking line;
  • Milling round headrig 8674 for thick timber sawing (diameter 14-45 cm);
  • Milling round headrig 8675, for thin timber sawing (diameter 14-28 cm);
  • Waste removal station for transportation of chips and sawdust away from headrigs;

In the framework of a modernization programme, the plant installeddrying kilns “Vanicek”; this allowed to increase dry timber output.

The technological sense of drying is prevention of dimensional and shape changes in finished products, as well as improvement of its characteristics — accuracy of sawing, milling, and sanding, higher bonding strength and better quality of final covering. Due to all these factors, “Ugra Saw Mills” produces free from inner tension high quality dry timber.
