vanerituotannossa

Vanerituotannossa is a Finnish term that translates to "in plywood production" or "in the production of plywood." It refers to the processes and activities involved in manufacturing plywood. Plywood is an engineered wood product made by gluing together thin layers of wood veneer. These layers, called plies, are typically rotary cut from logs and then assembled in alternating grain directions. This cross-graining technique gives plywood its strength, stability, and resistance to splitting.

The production process begins with selecting suitable logs, often from hardwoods like birch or softwood species. The logs are debarked and then rotary peeled to create thin sheets of veneer. These veneers are then dried to a specific moisture content and sorted for quality. Next, the veneers are coated with adhesive, usually a synthetic resin, and then stacked in alternating grain directions to form a "book" of plies.

The stacked plies are then placed into a hydraulic press, where heat and pressure are applied to cure the adhesive and bond the layers together. After pressing, the large plywood panels are cooled, trimmed to size, and often sanded to achieve a smooth surface. Further treatments like coating, painting, or laminating may be applied depending on the intended use of the plywood. Vanerituotannossa encompasses all these stages, from log harvesting to the final finishing of the plywood product.
