The effect of lathe checks on the mechanical performance of LVL

European Journal of Wood and Wood Products, 2020
Laminated veneer lumber (LVL) is an important engineered wood product manufactured by bonding veneers together in grain direction. To understand the effect of lathe checks on the mechanical performance, three types of LVL with different assembling approaches of layering by taking into account the veneer lathe checks, namely loose-loose (LL), tight ...

Ultrasound evaluation of lathe check depth in birch veneer

European Journal of Wood and Wood Products, 2008
In this study, the lathe checks in birch veneer were examined with contact ultrasound and a preliminary study for the measurement with air-coupled ultrasound from green birch veneer (moisture content 60–75%) was carried out. The contact measurements were conducted from dry veneer and then from moistened veneer.

The influence of lathe check depth and orientation on the bond quality of phenol-formaldehyde – bonded birch plywood

Holzforschung, 2013
Abstract During the rotary peeling of veneer for plywood or the laminated veneer lumber manufacture, checks are formed in the veneer that are as deep as 70–80% of the veneer thickness. The results of this study show that, during adhesive bond testing, deep lathe checks in birch (Betula pendula Roth.) veneer significantly reduce the shear

Simultaneous measurement of lathe check depth and the grain angle of birch (Betula pendula Roth) veneers using laser trans-illumination imaging

Wood science and technology, 2015
Lathe check depth (LCD) and the grain angle (GA) of veneer are important factors because they have an impact on the strength properties of plywood. Several methods to measure the LCD of veneer and the GA of wood or veneer have been developed over the years.
