Efficiency and Recovery with eWood-Technology Reducing Technology For decades EWD Reducing Technology stands for custom made sawline solutions for medium to large size sawmills. eWood is a comprehensive optimization and user interface software from EWD. All modern EWD sawlines and machines share the same interface application software. The interface man – machine offers an intuitive and consistent user concept, allowing effective use of the functions after just a short training period. • State of the art scanning and sensor technology • Professional optimization and operations software •...

CHIPPER HEAD Straight knives / Spiral knives for medium to large Reducing and Profiling lines The chipper canter PF 19 is used in circular saw or Reducer Bandsaw lines and also in Profiling lines for chipping of two parallel faces on logs or cants. The width adjustment of the chipper head supports is done by servo-hydraulic setworks. The chipper canter PF 19 can be fitted with either straight knives, spiral knives or stepped knives heads. The different head types are matched by the number of tools installed to the speed range desired. All heads are fitted with either pre- or post...

■ QUADROLINE Reducing - Bandsaw line EWD Bandsaw Technology stands for high recovery, flexibility and high performance. The demanding job of the saw filing of bandsaw blades is now done automatically by a new generation of stellite-tipping, grinding-, levelling and tensioning machines with highest reliability. New bandsaw steel qualities allow longer hours of operation with even thinner blade thickness. ^ FBS Flying Bandsaw active saw guide system with magnets for: • higher saw strain • higher sawing accuracy • higher feed speeds • longer operating hours The FBS Technology achieves...

SAW POSITIONING DISTANCES (in mm) stroke 450 350 Flexible double arbor circular saw for primary and secondary breakdown with excess height cutters and hydraulically height-adjustable saw arbors. The flexible double arbor circular saw unit DWK 700 is used as primary-, secondary break down or combination machine in medium to large sawmills. In total 6 pairs of saw heads can be positioned individually with very precise servo-hydraulic setworks. For a uniform distribution of the actual sawing heights on top and bottom saw blades, the saw arbors are automatically positioned in height. For the...

■ REDUCING LINE WITH MERRY-GO-ROUND EXAMPLE 1 3VA_±Ly Compact reducer line with a flexible double arbor circular saw DWK as the main break down machine. In primary break down up to 6 side boards of variable thickness and a variable thickness center cant can be sawn. In secondary break down up to 7 center products Feed speed range from 25 to 120 m/min. of variable thickness can be sawn. The outer saw Length of the reducing line: approx. 56 m heads can be fitted with fix-mounted saws on saw sleeves. The standard line is designed for log length from 2,5 to 6,0 m and a maximum log...

■ REDUCING LINE WITH MERRY-GO-ROUND EXAMPLE 2 3VA_±Ly Compact reducer line with a flexible Quad Bandsaw as the main break down machine. In primary break down up to 4 side boards of variable thickness and a variable thickness center cant can be sawn. In secondary break down up to 5 center products Feed speed range from 25 to 120 m/min. of variable thickness can be sawn. The example Length of the reducing line: approx. 56 m shows a flexible double arbor circular saw DWK to supplement the Quad bandsaw for cant resawing. The standard line is designed for log length from 2,5 to 6,0 m and a...

REDUCING LINE WITH MERRY-GO-ROUND example 3 Reducer line with two Quad Bandsaws as the main break down machines. In primary break down up to 4 side boards of variable thickness and a variable thickness center cant can be sawn. In secondary break down up to 5 center products of variable thickness can be sawn. Smaller diameter logs can be sawn in a single pass. Large logs are sawn in a very flexible way, using the merry-go-round system. The standard line is designed for log length from 2,5 to 6,1 m and a maximum log diameter of 75 cm, including taper and sweep. Feed speed range from 25 to 120...
