After soaking the birch logs are debarked. Then they are sent to the lathe where birch veneer is peeled from them. The log is centred on a lathe and turned against a broad cutting knife set into the log. Our peeling line enables us to produce veneer up to the length of 1850 mm. This is also the grain length. The maximum veneer width can be 2500 mm.

We check the moisture contents of our veneer with a moisture analyser from Sartorius, that uses the oven-dry method. This method is said to be the only reliable method to determine the humidity. Handheld moisture meters are only trying to estimate the oven-dry moisture content.

After drying the veneer is sorted according to the customer requirements. Usually, we put A and B grade together on the same pallet and C grade on separate pallets.

The veneer is packed onto pallets and the packs are labelled. Then the veneer is ready for loading and transport.

The veneer can be cut to size or narrower strips can be put together with glue threads. The threads are put on one side of the veneer. They keep the narrower veneer pieces in place. Such composed veneer sheets can effectively be used as core layers in plywood or bed slats.
