Abstract
The present invention concerns a method that is timesaving, more economical and facilitates the handling and processing of short solid wood planks. Tongue-and-groove joints are machined on the short sides of the short green planks enabling their releasable tight assembly in rows for the seasoning process in the kiln dryer. This temporary attachment between adjacent planks prevents exposition of the short sides to the drying air thus avoiding the usual end grain checking on the latter during kiln drying, and eliminates the need of performing any subsequent machining and trimming steps after the expensive kiln drying step. This process then also improves the saving opportunities by increasing the volume of wood drying capacity and by increasing the production of reusable green wood shavings as opposed to unusable wood shavings following the kiln drying operation.
