Sawed
veneer
Our choice to develop the production of sawed veneer can be explained
by the fact that being able to obtain sawed veneer without having
to steam the wood for several days, as would be the case for sliced
veneer, brings a major quality asset to our products.
The origin of our sawing method ("au bois montant") can
be traced to the end of the XVIIIth century. It enables us to get
high quality sawed veneers. Their current thickness range from 12
to 15/10 mm. As we don't have to steam the wood, the latter doesn't
need to be washed, thus keeping all its tannins making it much more
resistant to the damages of time. It is known that the pores and
fibers of steamed wood have a strong tendency to slacken.
Sawing veneers implies a perfect cutting of the fibers by the blade
of the saw, which means that the blade must be extremely well sharpened.
Our sharpening method enables to obtain this quality. The wood surface
looks as if it was slightly polished. The sawing marks are hardly
visible, thus reducing finishing delays and loss of matter. If observed
with a binocular, our veneers show no hint of fiber pulling out,
which avoids damageable sawing marks which can be very difficult
to eliminate, and sometimes can reappear at varnishing time.
The drawings on the left explain how the slicing technique works
and show why sawed veneer is much preferred.
Slicing consists in pushing in a perfectly sharpened blade, solidly
fixed in a blade holder and duly stabilized, into a piece of lumber
that has been placed for some time in steam or boiling water.
In front of the blade, a pressure bar can be seen which, pushing
on the piece of lumber, ensures a regular thickness. It is obvious
that even though the blade is well sharpened, it inevitably provokes
a pulling out of the fibers, more or less important according
to the wood hardness and structure.
On the surface of sliced veneers, the presence of pulled out
zones can be noticed, which implies many difficulties at finishing
time for rubbing down and polishing. It can also be mentioned
that sliced veneer being much thinner than sawed veneer (ca. 6/10
mm for 12 to 15/10 mm), "holes" may occcur.
As far as hard wood species are concerned (tulip wood, king wood,
rosewood), micro-fractures are often reported under the varnish.
These micro-fractures become very visible under an oblique low
light, which enables us to distinguish the sliced parts which
may have been glued on a piece of furniture which was originally
made with sawed veneer.
This is how you can tell whether a piece of furniture is an original
XVIIIth century work.
Sawed veneer is also much appreciated by designers for panelling
because they have exactly the same colour and aspect as solid
wood.
