Abstract
A method of producing reconstituted wood boards in a conventional press by introducing saturated steam through apertured press platens into a partially-compressed mat, composed of lignocellulosic material and a thermosetting resin binder, under specified conditions of mat density. Use of saturated steam in this manner allows production of a reconstituted wood board with shorter total press time than usual and with a more efficient use of energy. In addition total press time can be further reduced by injecting a gaseous catalyst into the mat to speed the cure of the thermosetting resin binder.
