PLYWOOD TECHNOLOGY

Plywood is a board made from thin sheets of construction veneers which are bonded in layers to create a strong and stable board. Veneers used for plywood construction are cut from a log for constructional or decorative purposes. The two most common methods used for veneer production are called saw and rotary cutting. Constructional veneers on the other hand, are cut using the second method named rotary cutting. The knife blade peels thin sheets of wood and it is an efficient way to produce veneers, as they can be cut to any width.

Plywood is most commonly made using an odd number of veneers, three being the minimum. However, the number of veneers used depends on their thickness and the finished plywood board. The veneers are bonded with an adhesive at right angles to one another to reduce the shrinkage and improve the strength.
