The advantages of the Flying BandSaw Technology
•
Relieving the saw blade of stress through conventional pressure guides allows the introduction of higher saw strain
and higher saw speeds.
•
The exact tracking of the bandsaw blade as it passes through the lumber is achieved by the magnetic forces of the
FBS Technology and allows achieving substantially higher feed speeds.
•
The results are constantly accurate sizes and notably higher production.
•
The FBS Technology achieves excellent production results in summer and winter operation.
nal saw grinding companies allows calculating the tooling costs very easily.
The 17° slanted bandsaw headrig and
carriage gain more and more acceptance.
The advantages of the slanted design are enormous:
•
The loading of the logs onto the carriage is significantly faster
due to the easy transfer.
•
The sawn face of the log can be well seen.
•
The transfer of the sawn lumber onto the discharge conveyor happens fast,
gentle and in a safe way.
•
Due to the slanted set-up, the lumber lands on the transfer conveyor with
the narrow face up.
•
As a result the further processing of the lumber is easier.
•
The high degree of automation and a modern control stand allow one
operator to monitor besides the bandsaw headrig operation the automatic
performance of edger optimizer, flitch cross-cut saws and circular resaw as well.
The modern EWD Log Bandmill Technology makes
the 1 operator sawmill become reality.
