ABSTRACT:
A method and apparatus for testing the stiffness or strength of wood panels while the panels are moving along a production line, in which the panels are moved lengthwise through a tester having lower rollers which are situated to support side or end marginal portions only of the panel while central upper rollers contacts a central region of the panel and subjects the panel to longitudinal or lateral bending. The forces corresponding to the bending are measured and used to obtain a measure of the stiffness or strength of the panel. Preferably, both a longitudinal and a lateral tester are provided, and each have two testing stations each applying a different amount of lateral bending, all of these amounts being in the substantially linear portion of the load deflection curve.
