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.

Abstract: A wood-base building component of cellulosic particles and/or fibers and adhesive binder is, in a single pressing operation, molded into an integral product of sheathing and support members for use in constructing wood-frame buildings. The dies utilized during press-molding form a flat panel containing a plurality of evenly spaced channels that serve as support members to replace conventional framing such as studs, joists, and rafters. The integral product may serve as roof, wall, or flooring components in the usual wood-frame building applications.
