An essential component of optimizing recovery and value creation is a precise cutting position, particularly with finger jointed products. The "dual scatter" system, comprising a line laser and a dot laser, enables this precision. While the line laser primarily detects knots, cracks and resin pockets, the dot laser particularly improves detection on rough surfaces. The cutting position is decisively improved via the angle and size of the dots. This guarantees stable finger jointing. "Dual scatter" is available for hardwood and softwood.
