Abstract
A process for the continuous production of a surface-consolidated lumber, in which the surface layer of a lumber to be treated is hardened and consolidated, is provided. In this process, a lumber to be treated is coated with a thermosetting resin and is then fed between hot-pressing rolls in a plurality of pairs of hot-pressing rolls, and the lumber is continuously heat-compressed between the hot-pressing rolls and simultaneously the thermosetting resin is cured, whereby the surface of the lumber is hardened and consolidated.
