1. Introduction to Rotary-Peeled Veneer

Rotary-peeled veneer is a type of wood veneer that is produced by rotating a log against a blade, peeling it into a continuous sheet. This method is one of the most common techniques used in the veneer industry due to its efficiency and the ability to produce large sheets of veneer. The resulting veneer is thin, flexible, and can be used in a variety of applications, from furniture to architectural paneling.

1.1 What is Veneer?

Veneer refers to thin slices of wood that are typically glued onto core panels (such as plywood, particleboard, or medium-density fiberboard) to produce flat panels such as doors, tops and panels for cabinets, parquet floors, and parts of furniture. Veneer is also used in marquetry.

1.2 History of Rotary-Peeled Veneer

The technique of rotary peeling dates back to the early 19th century when it was first developed as a method to produce thin sheets of wood for various applications. Over time, advancements in technology have made the process more efficient, allowing for the production of high-quality veneer at a lower cost.

2. The Manufacturing Process

The manufacturing process of rotary-peeled veneer involves several steps, each crucial to ensuring the quality and consistency of the final product.

2.1 Log Selection

The process begins with the selection of suitable logs. The logs are chosen based on their species, size, and quality. The ideal log for rotary peeling is straight, free of defects, and has a consistent diameter.

2.2 Log Preparation

Once selected, the logs are prepared for peeling. This involves removing the bark and cutting the logs to the appropriate length. The logs are then softened by steaming or soaking in hot water, which makes them easier to peel.

2.3 Rotary Peeling

The softened log is then mounted on a lathe, where it is rotated against a sharp blade. As the log turns, the blade peels off a continuous sheet of veneer. The thickness of the veneer can be adjusted by changing the angle of the blade and the speed of rotation.

2.4 Drying and Clipping

After peeling, the veneer sheets are dried to reduce moisture content. This is typically done using a dryer that circulates hot air around the sheets. Once dried, the veneer is clipped to the desired size and trimmed to remove any defects.

2.5 Sorting and Grading

The final step in the manufacturing process is sorting and grading the veneer. The veneer is inspected for quality and sorted based on its appearance, grain pattern, and any defects. Higher-grade veneer is used for visible surfaces, while lower-grade veneer is used for backing or less visible areas.
