Finnish sawline in Idaho

Not every company uses the world's leading wood trade fair Ligna as globally as Veisto from Mäntyharju/FI does. Their HewSaw-sawing lines can be found on every continent and in most time zones. Moreover, the recent installations were anything but a home match for the Finns. Just recently, the Idaho Forest Group of Lewiston/US decided in favour of the Finnish technology. Other reference projects which were proudly presented at the booth on the Ligna 2013 were sawing lines for N. F. McDonnell & Sons in Australia, Lavrama in Brazil or Stenvalls Trä in Sweden.

"Particularly winning the bid in Idaho has been a great success for us", said Tuomo Kauppinen, sales manager for Central Europe. For the first time ever, Veisto succeeded in selling a high performance sawline to the US which rips the logs in a number of chipping units. "Previously, we only installed our single-unit systems which we call HewSaw-R'-sawing lines", said Kauppinen. Yet in Lewiston, a HewSaw SL250 3.4-line has now been installed. The Finnish flagship is geared for producing American construction lumber 2-by-4 and 2-by-6. The line produces up to eight boards from log up to 45 cm head log. To achieve this, it features four chipping heads, the last one of which can make the cut after the cant has been rotated 90 degrees. The SL 250 3.4 in Lewiston operates both in an unsorted and a sorted mode. It all can be done while curve sawing as well, with optimized cutting patterns and perfectly fitted side boards. The feed rate is up to 180 m/min. How can the line keep up precision at this rate? "Our new dual rotor login system takes care of that. The first rotor positions the log roughly, the second turns it precise to the degree", Kauppinen explained at the Ligna in Hanover (see picture).
