Weather-proof wood veneer manufacturing method for e.g. form plywood, involves thermally re-retreating veneer of preset thickness at temperature of predetermined degree centigrade over preset time, as wood veneer

摘要

The method involves thermally re-retreating a veneer (12) e.g. cutter veneer, of thickness with 0.8 to 2.5 millimeter with residual moisture of 12 percentage at a temperature of 180 to 260 degree Centigrade over a preset time, as a wood veneer. The cutter veneer is adjusted as the wood veneer to a fiber saturation point of 25 percentage. Dried wood veneer is thermally re-treated by contact heat or in a drying furnace. The wood veneer is thermally re-treated in a through-feed process. Independent claims are also included for the following: (1) a wood veneer for manufacturing a form plywood (2) a form plywood comprising a set of wood veneers.
