Zusammenfassung: | A process of manufacturing a plywood panel which includes the steps of producing a plurality of green veneer sheets of random size or widths less than the length or width of the plywood panel to be manufactured with the grain of the wood running lengthwise of the sheets and having a typical moisture content from about 30% to about 300% of the fiber weight, stitching a plurality of the green sheets together in side-by-side relation across the grain of the wood with thread having shrinkage characteristics about the same as that of the green veneer, typically 5% to 10% to produce an assemblage of sheets slightly larger than the plywood panel to be manufactured, drying the assemblages of sheets in conventional veneer driers, and subsequently assembling the dried assemblies of sheets with other veneer sheets or assemblages of sheets into a plywood panel. |
