Method of making overlaid plywood

摘要

Overlaid plywood is made by filling surface defects on a plywood panel with a thermosetting resin; overlaying the filled surface(s) with sheet(s) of overlay paper and then compressing the panel, while heating the panel. Gluelines in the plywood veneer and in the overlay paper(s) are cured during the hot pressing operation, which also flattens and hardens the resin-filled defects to form a smooth-surfaced overlaid plywood panel.
