The production and final use of our
Rotary Cut Veneer of Beech

The beech veneer business starts even in the forest. The beech logs have to be selected very carefully to get wood with a small brown heart. Besides the workers in the forest and the transport company have to pay attention because the felling and subsequent operations causes sorne, but nevertheless dangerous cracks on the end surfaces of the logs and should be avoided as good as possible. A rather primitive but to some extent effective measure is the use of iron clamps. It is essential that these clamps are inserted in the end surfaces before the drying process starts and before loading on trucks. After this prevention, the logs should be put in wet storage to prevent the drying. The felling period of Beech logs start in November until March because of that, a big quantity had to be stored under water, to be able to produce every time.

For this we have a roundwood yard for nearly 9000 cbm with automatic water spraying. The following steaming process gives plasticity to the logs and the equal salmon-pink color to the later rotary cut veneer of Beech. We have 4 steaming pits of each 18 m long. The stearning process is indirect, and therefore very careful for the logs. Temperature and timing of the steaming process are controlled by a full automatic computer system 7 days round the clock. Before the feeding and centering unit the sawn logs are debarked by modern automatic rosser head. The veneer is clipped automatically by a camera controlled clipper before drying. A new automatic unstacking system makes it possible to peel with 90 m per minute without winding up before. The following drying process is affected in a specially constructed roller veneer dryer with air circulation across the axis of the dryer, to get plain and flexible pieces of veneer. Two separate temperature sections are controlled automatically just like the moisture-content.

The outgoing veneer at this machine is now sorted in accordance with the special requirements of each client. The quality had to be fixed for the later use for moulded plywood, laminated wood, as cross-band veneer for coreboards or other types of plywood. Nearly 75 % of our produced Beech veneers are used for the seating construction especially light colored armrests and naturally big quantities for shells of chairs.

"A well-sorted veneer range is half the battle. With Sinnerbrink beech."

Our deliverable thicknesses in Beech are from 1 mm to 3.00 mm. Nearly every thickness between is possible. Our standard is 1.00; 1.20 mm and 1.50 mm. Here we have the most possibilities for combination with many specifications to get high proportions of surface (A or AB) quality. The export rate in this moment is nearly 90% with shipments in all over the world. Every week 20 ft-or 40 ft hc containers are shipped with high routine. The quantity for a container is calculated exactly to get a volume of minimum 18-18,5 cubic meters per 20 ft-container (40 ft-container approx. 34 cubic meters). The export pallets are build from 100 x 80 mm sturdy square logs and covered with 30 mm chipboard to prevent waviness. We can not give any prices in here, because they depend on individual quality requirements of the final use at the client.
