Wood veneer might seem easy, but it is a sophisticated technique where little details have big importande. Here is a quickly overview to the production of this material
Logs are not just the prime material, they are also one of the main values of the final product. Therefore Channel veneers selects and collects the best trees all over the world. More than one hundred different log specifications are considered to fit the supply to the demand.
Due to the loss of moisture, logs might break and loss part of their aptitude to became veneer. Despite of this, logs should be kept at every moment under an artificial rain that ensures the best conservation of the raw material.
Logs ought to be prepared before they might be spliced and transformed in veneer. First operation to be done is to take away the bark and cut the log attending to the final direction of the splicing: Crown cut, Quarter cut or Rift.
Logs are two hard to be cut as thin as veneer. Despite of this they must be cooked in hot water for hours in order to soft them.
After the hot bath, the log is nearly ready to be spliced. Last operation before it is to take away sapwood. The cleaning of the log is finish when it is calibrated and the irregular extremes are taken away.
Probably the most impressive operation in wood veneer production is the splicing. Every second the log is moved over a blade and a wood veneer falls out of the log. At the same time the log is moved towards the blade less than a millimetre so that the next second another sheet of wood will be taken out of the tree.
Wood veneers are quickly dried to avoid their cracking despite of the lost of moisture. This process ought to be solved at the same speed as splicing, as long as green veneer is not a stable material and might not be storage.
As soon as the veneers are coming out of the dryer, wood sheets are classified attending to their visual quality and dimensions.
Veneers with similar dimensions are cut to fit a regular and rectangular size and then are packed together specifying their origin, number of sheets and dimensions.
At the end of the production line squared packages are classified again in order to define homogenous quality groups of packages, the logs.
