Tolko is investing in a new BioVision Edger line for its sawmill at Armstrong, BC.

The new line will comprise an unscrambler, Maximizer positioning infeed with dual fetchers, 4-saw edger, and close-coupled picker tailer. The optimizer is a BioVision system utilizing data from the new transverse scanner fitted with BioLuma 2900LV vision sensors. Also included is a MillTrak™ lumber flow control system comprising two sensors mounted above the unscrambler.

BioVision’s edger grade evaluation adds overall value through re-manufacture or rip, based on the final grade of the wood. For example, a #3 appearance due to knots can be edged to #3 wane with confidence, to maximize recovery. Likewise a low grade 2×8 may be worth more as two 2x4s, one being a higher grade.
