ABSTRACT:
Moisture in wood veneer strips received from a drying oven is measured by passing the veneer strips on a conveyor between arrays of plates including a transmitting plate on one side of the veneer and a juxtaposed receiving plate on the other. Phase plates on either side of and on the same level as the transmitting plate are empowered by a signal having the reverse phase to that applied to the transmitting plate, and when wet veneer passes between the plate arrays, part of the transmitted signal is shunted, placing the veneer at virtual ground level and reducing the signal received by the receiving plate. A plurality of diagonal passages in the lower plate array receive air under pressure for conveying the veneer strips thereover.
