<p>Improvements in Methods and Apparatus for Conditioning Plywood veneer with High Frequency Radio Energy There are disclosed in the present application, methods and apparatus for reprocessing sheets of veneer which have received an unsatisfactory first drying treatment resulting in wide variations in the percentage of moisture in various parts of a given sheet and in the average moisture from sheet to sheet. In the present apparatus, veneer sheets somewhat larger than four by eight feet are subjected in a stack or batch to radio frequency energy, heated air below the boiling point of water and variable pressure to accomplish both a redistribution of moisture and the elimination of excess moisture to prepare the sheets of veneer to be bonded together to form sheets of plywood.</p> |
