Veneer production

From tree to single leaf – veneer production in detail

A truck delivers the purchased logs to the veneer mill.

All logs are stored in the mill yard until production begins. Proper storage includes continuous sprinkling with water. The moisture prevents cracking caused by drying and any changes in color.

The logs are cut and prepared for further use.

Each log is processed into flitches with a specified cutting technique. For more information see the page on veneer production techniques.

The bark is removed (stripped) from the raw wood in preparation for the slicing and peeling machines. At the same time, any foreign material such as embedded stones, hammered-in nails, sand and soil are removed.

Steaming (or cooking) the logs in hot water has two purposes. First, it gives the wood the pliability required for a smooth cut and thus perfect processing quality. Secondly, the length of time the wood remains in the water affects the color of the veneer.

Burls are peeled into thin veneer leaves.

Logs are sliced according to specified technique. The quality of the processing depends on precise setting of the blade with an accuracy of 0.1 mm. Only then can faultless quality be guaranteed.

The still-wet veneer sheets are dried in dryers between webbing belts, which also flatten (smooth) the sheets.

When the veneers are dry, they are cut to size and bundled into flitches. The edges are trimmed and if necessary, growth irregularities are cut out.

After the veneers are cut, they are bundled into packs (flitches) of 16, 24 or 32 sheets (leaves) each.
