Description

A solid wood laminated veneer line

technical field

The utility model relates to a solid wood laminated veneer line.

Background technique

At present, there are two main methods for the production of solid wood veneer lines. One is pure solid wood lines. In order to ensure the surface quality of the lines, the quality requirements for solid wood are relatively high, and it is necessary to use more precious high-quality pure solid wood (logs) Through four-sided planing or vertical milling, milling into pure solid wood lines, the processing volume is large and a large amount of high-quality wood is wasted. After milling, the veneer of the precious tree species is used for milling to make solid wood cladding lines. Pure solid wood lines must be processed with high-quality wood. Since a single high-quality pure solid wood is used, its grain direction is uniquely determined, which is expensive and easy to deform along the grain direction, and the quality is unstable; and solid wood cladding lines, using The wood composite is solid wood, the price is relatively moderate, and it is the mainstream product in the current market, but because it is composed of a variety of irregular solid wood, the texture is disordered, the stress distribution is scattered, the quality stability is poor, and the phenomenon of cracking is more serious.
