High feed speeds and large cutting depths as a result of modern
technology applied to woodworking have made it necessary to deal with the problem of
overheating and of the inner tension of the machine saw blades. A number of special
features indispensable now in the woodworking industry, particularly in the saw mills,
originated from these efforts. Cooling by slots and cutouts, improved clearance by raker
teeth and their special position in the plate are marks of success in the fight against
overheating of circular saw blades. Thus, it has become possible to retain the very
important inner tension of circular saw blades even for a very long time of operation
during which restraightening and retensioning is no more necessary.
Untipped circular plate saws and gang saw blades are
hardchrome plated so that they offer a longer service between resharpenings. In our own
modern hardchrome plating facilities the hardchrome thickness can be kept at the desired
constant level so ensuring that resharpening is only necessary at the very longest
Measures for the conservation of environment comprising noise
reduction are increasingly welcomed. The disturbing and harmful noise by high sound
intensity levels of circular saw blades has always been a nuisance in the woodworking
industry. In cooperation with the Technical University Braunschweig we have developed a
sound damped carbide tipped circular saw blade so making an important contribution against
For Gang Saw Machines
Special emphasis has been given to the field of gang saw
blades and the auxiliary suspension equipment for the saw mill industry.
Two assets developed for this area:
- The special Ti-design for gang saw blades making
retensioning dispensable and increasing the long-term efficiency substantially.
- A new fully automatic hydraulic tensioning system waiving
the tedious manual pretensioning of the eccentrics by hand.
|Modern Sawing Technique
Due to their ingenious design Felde products such as machine saws,
machine knives, suspension systems and other equipment for the saw mill industry will give
an optimum efficiency to the industrial user. Even at very difficult cutting conditions,
for instance when cutting large depths of wood at the quickest possible feed speeds our
machine saw blades will perform with a very small loss of cut yielding a smooth surface
finish of the wood and causing a minimum down-time thus constituting low-cost purchases.
It is the special rip cutting circular saw blade which is increasingly used for the
cutting of small and medium diameter soft wood trunks due to the advance of the profiling
technique in the saw mill industry in the past years. Installed on heavy duty woodworking
machines such as double arbour machines and log slabbers our special circular saw blades
with rakers have proved to be the best procurable. Felde products used on saw mill
machines such as edgers, multiple saw machines and high duty gang saw and band saw
machines cut the cost of production substantially.
