  • Method of drying wood veneer
    Patent number: 6401356
    Abstract: A method of drying veneer sheets by continuously shingling discrete wood veneer-sheets to form a layup where the leading edges of adjacent sheets are offset by a distance X with the lower, veneer sheet leading in the direction of movement the one there above and continuously feeding the so formed layup in the direction of movement into a drier where the veneer sheets while still in the layup are dried. The dried veneer sheets are then separated into discreet dried veneer sheets and are thereafter individually tested.
