details about the rotary peeling step in the manufacturing process of plywood:

  • Rotary peeling: The logs are peeled into thin sheets of veneer using a rotary saw. The saw rotates the log while a knife cuts off the veneer. The thickness of the veneer is controlled by the speed of the saw and the distance between the knife and the log.

The rotary peeling process is the most common method for producing veneers for plywood. It is a fast and efficient process that can produce large quantities of veneers.

Here are some of the advantages of rotary peeling:

  • It is a fast and efficient process.

  • It can produce large quantities of veneers.

  • It is a relatively inexpensive process.

Here are some of the disadvantages of rotary peeling:

  • It can produce defects in the veneers, such as knots and cracks.

  • It can waste wood, as the bark and the center of the log are not used.

  • It can be a noisy process.

By carefully controlling the process, plywood manufacturers can minimize the defects in the veneers and maximize the yield of wood.

Here are some additional considerations for the rotary peeling process:

  • The type of wood: The type of wood affects the speed of the saw and the distance between the knife and the log. Softwoods are typically peeled at a faster speed and with a smaller distance between the knife and the log than hardwoods.

  • The moisture content of the wood: The moisture content of the wood affects the thickness of the veneer. Wet wood will produce thicker veneers than dry wood.

  • The temperature of the saw: The temperature of the saw affects the quality of the veneer. A hotter saw will produce a smoother veneer.

By carefully considering the factors involved in the rotary peeling process, plywood manufacturers can ensure that they are producing a high-quality product.
