Engineered wood floor using core material with vertical glue-line position

Abstract

A composite board comprising a first layer having an orientation and a second layer bonded to the first layer where the second layer comprises a plurality of wooden veneer structures, each wooden veneer structure is substantially perpendicular to the orientation of the first layer.

AI Technical Summary

Benefits of technology

The wood veneer composite core with vertical glue lines enhances dimensional stability, structural integrity, and surface durability, reducing processing costs and material weight, while providing consistent stability characteristics and improved sound absorption.

Problems solved by technology

Solid wood floor is known to have less stability in climate change due to the inherent swelling-shrinking nature of wood.

Though a solid wood floor can be installed using various different installation methods, their irregular sizes may prohibit certain installation types.

The mixed cutting directions of slats in the assembled core layer hardly gives a predictable dimensional stability characteristics in relation to the material's random shrinking-swelling directions, whilst the moisture content of the individual piece can hardly be homogeneous in relation to the drying time of the lumber pieces which have various cutting directions.
