SAW TECHNOLOGY REVIEW – DOUBLE EDGER FROM RESCH &3
Resch &3 cutting a successful path
Willemsen Naaldhout B.V.. based in Cuijk is the largest needle sawmill in Netherlands annually processes 300,000 m3
Resch &3 Double edger DB 65 & DB 90
roundwood (pine, spruce, Douglas fir and larch). The flexible saw lines are some of the most modern in Western Europe. This makes it possible to easily and quickly switch such packaging timber
to lumber for the civil engineering sector or garden timber.
As a supplier of sheet piles including (for the civil engineering), pallet boards and spool wood (for the packaging industry) and garden wood Willemsen Softwood BV plays a leading role.
Since September 2011 Willemsen has used a
Resch &3 stationary band saw type ES 1050 PROFI for cutting mainly large trees. They also use the new Resch &3 double edger DB65. IFI has a full Operation Focus on the band saw in our next issue. Meanwhile we report on the Double Edger DB65.
Precision: The plank remains lying on the table and the saw head moves forwards and backwards. There are also two pressure rollers in front of and behind the saw blades, which put downward pressure on the plank and fix it in place. This new working process is the only one of its kind on the market and guarantees an accurate, parallel and straight cut.
Space saving: Less space is needed, as instead of being pushed through, the plank remains lying on the table.
Operated by just one person: The machine is operated by one person. A conventional double edger, which requires the plank to be pushed
through, needs one operator at the in-feed end and another at the out-feed end.
Maximum efficiency: The motors of the circular saw blade are constantly monitored and the optimal feed rate is automatically adjusted.
No suction unit is required: Thanks to the saw blade’s rotation speed, the sawdust is ejected into a collection box. This box is emptied every time in final position.
Easy to operate: Each individual plank is aligned using cross chains at the zero-line (= left, fixed saw blade) by means of a laser guide. The second moveable saw blade is subsequently adjusted (also using a laser guide) so that maximum yield is ensured. A specific measurement can also be set at the control panel. Lateral stops, adjustable from 3 to 16 cm, facilitate multi-ripping. IFI
