A timber mill has specified the use of flexible drives on all of its new timber board handling equipment to help ensure accurate positioning. Stora Enso, a paper, packaging and timber company, has a timber mill in Varkauden Saha, which produces 345,000 cubic metres of cut timber annually, with all by-products going to pulping for newsprint manufacture at the nearby paper mill or being used for biomass heating in a combined heat and power plant at the paper mill. Stora Enso has invested around 20 million euros in the plant, with the installation of new planing and edging lines and a new automated board handling, sorting and stacking plant. The production line at the sawmill receives spruce logs (minimum length 2.5m) and takes them through debarking, profile cutting and six-blade sawing to produce a range of sawn timber mainly for the house-building industry. The plant also produces board for the building trade. At each stage of the process, chipping, sawing, sorting, stacking and packaging, it is crucial to provide O.lmm positioning for grinding rolls, chippers and saw-blade positioning.
