A method of manufacturing engineered wood is provided, the method including: feeding wood through a processor while exposing the wood to compressive and tensile forces to produce naturally oriented strands of fibers; adding an adhesive to naturally oriented strands of fibers to provide adhesive covered strands; feeding the adhesive covered strands into a press; applying a first pressure to the adhesive covered strands to provide a pressed wood with a selected first dimension and a selected second dimension; and applying a second pressure normal to the first pressure to the pressed wood to provide an engineered wood having the selected first dimension, the selected second dimension and a selected third dimension and a selected density. An installation for manufacturing the engineered wood is also provided.

The invention relates to a method for extruding wood pellets, the method being characterized in that it comprises at least the steps of: (a) providing pieces of wood; (b) grinding and partially drying, in a twin-screw extruder including at least shear generating elements, pieces of wood to obtain wood particles having a reduced water content compared to the pieces of wood; (c) compressing the particles and shaping in at least one die to obtain wood pellets.

The invention also relates to a wood pellet capable obtained with this method and a co-rotating twin-screw extruder intended for the extrusion of wood pellets

Comminution process of wood chips to produce wood particles, by feeding wood chips in a direction of travel substantially normal to grain through a counter rotating pair of intermeshing arrays of cutting discs arrayed axially perpendicular to the direction of wood chip travel, wherein the cutting discs have a uniform thickness (Td), to produce wood particles characterized by a length dimension (L) substantially equal to the Td and aligned substantially parallel to grain, a width dimension (W) normal to L and aligned cross grain, and a height dimension (H) aligned normal to W and L, wherein the WH dimensions define a pair of substantially parallel end surfaces with crosscut fibers.

A wood chipper, a flywheel therefor, and a process of making the flywheel. A plurality of plates are laser cut to each have a thickness up to about inch, including laser cutting a plurality of apertures in each of the plates and laser cutting a central opening in each of the plates for receiving a shaft for effecting rotation of the flywheel. The plurality of plates are laminated together by inserting fasteners in corresponding ones of the apertures in the plates. At least one knife is attached to the laminated plates for cutting wood material to form chips of the wood material as the flywheel is rotated.

A wood chipper includes a frame, an infeed system, a rotatable cutting system, and at least one feed wheel disposed between the infeed system and the cutting system to feed wood material to the cutting system. The wood chipper also includes a winch which includes a winch line having a first end, and a collar disposed adjacent the first end of the winch line. The wood chipper further includes a detector adapted to detect a first and a second position of the winch line, wherein the detector is adapted to allow operation of the at least one feed wheel and prohibit operation of the winch when the first position of the winch line is detected, and to allow operation of the winch and allow operation of the at least one feed wheel in a predefined manner when the second position is detected.
