Abstract

The invention relates to process of manufacture of wood products such as plywood and form pressed panels with improved production efficiency where an adhesive system (adhesive and hardener) is used together with a separate application hardener to facilitate the high production efficiency or production at reduced temperature or the combination of both. The process has at least 3 and preferably less than 50 alternating veneer layers A and B and comprises the steps of; - providing a glue mixture of adhesive I and hardener II on both sides of veneer layer(s) A; - providing a water based hardener III on both sides of veneer layers B; - laying-up in a stack at least one of said veneer layers A alternating with at least two veneer layers B - pressing the stack at elevated temperature and pressure to form the form-pressed product; and wherein said veneer layers A and B are stacked such, that the hardener III on veneer layers B get in contact with the glue mixture on veneer layer(s) A during pressing; and wherein the first and the last veneer in the stack should only have glue mixture or hardener solution on the inner side of the veneers, to avoid sticking in the press.
