Your reducer line with merry-go-round system for high capacity within limited space

The RED flex is a chipper canter-circular saw line with reducer technology. Due to the automatic merry-go-round system allowing up to three passes, you only need little floor space to convert your logs into centre products and unedged sideboards. The processing sequence for the logs and two-sided cants is designed in such a way that the saw line achieves the highest possible capacity. As with all LINCK saw lines, you decide what you need and we design the reducer line exactly according to your requirements.

Key data

  • Processing up to 75.000 m³ of round logs per year and shift
  • Feed speed from 30 to 100 m/min and more– depending on the configuration
  • Operating mode: processing of unsorted logs
  • Merry-go-round system for two-sided cants allows up to three passes
  • Log diameter, large end, 55 cm
  • Log diameter, small end, 12 cm
  • Log length 3,00 to 6,30 m
First pass through the chipper canter-circular saw group: with precise log rotation for a value-optimised result


In the first pass, the chipper canter-circular saw group converts the log into a two-sided cant. Based on the LINCK specific evaluation of the 3D-scanning data, the infeed system fully automatically rotates the log prior to entering the chipper canter - either large or small end first. The merry-go-round system then transports the two-sided cant back for a second pass. The unedged sideboards are fed towards the board edger plant.

Value-optimised sideboards, based on 3D-scanning with LINCK optimising algorithms

The 3D-scanning is the base for the best possible utilization for each individual log. Based on the collected 3D-data, the LINCK optimizing algorithms will determine the best possible value-optimized sideboard. This interpretation embodies all of LINCK's extensive know-how which will give you the best out of each log.

Precise log rotation

The more precise the infeed, the more accurately the chipper canter can implement the determined cutting pattern. With a standard deviation of +/- 6°, the automatic chipper canter infeed system in a LINCK line is very precise. For comparison: 6° corresponds to one minute on your clock dial.

Second pass through the chipper canter-circular saw group: maximum througput by optimum integration of the merry-go-round system

The chipper canter-circular saw group uses the second pass to convert the two-sided cant into a four-sided one and to produce unedged sideboards. This pass starts when the merry-go-round conveyors are filled up. An additional 3D-scanning is possible before the second pass to further optimize centre products and sideboards. After having processed all two-sided cants, the saw line starts again with feeding fresh logs for the first pass or carries out the possible third pass.

Circular saw working with the double arbor principle for reduced saw kerf

The circular saw works according to the double arbor principle with two saws. Saw kerf is reduced by distributing the cutting force equally to two sawblades.

Separating conveyor reliably separates the sideboards

The separating conveyor reliably separates the sideboards from the centre products, even with multiple centre products.

Four-sided scanning for further optimisation

Scanning of the four-sided cants before the next step guarantees an accurate downstream processing on the basis of the already produced surfaces. In addition, it is possible to automatically and continually monitor and compare the optimization results between the initial log and the current cant scan.

Third pass through the chipper canter-circular saw group: tailor-made quality of the centre products


The chipper canter-circular saw group even allows a third pass to saw the centre products into the required number of boards. For this purpose, the four-sided cant is returned to the beginning of the machine group and processed as soon as the feeding station is filled. As an alternative to the third pass, a resaw can be installed downstream the chipper canter-circular saw group for centre product splitting.
