    摘要： An article having non-planar portions, such as a material handling pallet, including a substantially flat deck member and a plurality of hollow leg members projecting integrally from the deck member, is molded as a one-piece unit from a loosely-felted mat formed from a mixture of resinous particle board binder and flake-like wood particles. The leg members are preformed in a separate preform mold or the article forming mold and the mat is deposited on the female die over mold cavities containing the preforms. When the article forming mold is closed, the mat and preforms are compressed into substantially the desired shape and size under temperature and pressure conditions which bond the wood particles of the mat and the preforms together to form a unitary structure.

    摘要： Apparatus for forming a loosely felted mat of thin elongated wood flakes with said flakes being aligned in mutually parallel relation. The apparatus includes a mat supporting surface, a hopper for holding a quantity of wood flakes, and a funnel assembly for receiving wood flakes from the hopper and for causing the flakes to be aligned in substantially parallel side-by-side relation as they are deposited on the supporting surface. The funnel assembly includes a plurality of funnels positioned in adjacent side-by-side relation, the funnels each including inclined walls having lower edges defining an elongated narrow opening adjacent the supporting surface and upper edges defining an opening wider than said narrow opening and for receiving wood flakes from the hopper. The narrow openings of the funnels are parallel and distribute the flakes uniformly across the supporting surface.

    摘要： A method of producing molded wood flake or strand three-dimensionally curved products using draft angles of 10 degrees or larger with little or no blistering or wood flake springback from over densification. A loosely felted mat of wood flakes is placed between top and bottom molds which slidably engage one another at pinch points to pinch and sometimes remove excess flashing/pinch trim.

    摘要： A fingerling shear for shearing a length of wood in a plane transverse to the grain direction and for splitting the sheared length along the grain direction to form a plurality of fingerlings. The shear includes a planar shearing blade, supported for rotation about a generally vertical axis, the planar shearing blade including an involute cutting edge adapted to engage the elongated piece of wood during rotation of the blade and for shearing off a length of that piece of wood, and a plurality of splitting blades fixed to the lower surface of the planar shearing blade and spaced along the involute cutting edge, the splitting blades each including a leading cutting edge spaced from the involute cutting edge of the planar blade and extending tranversely to the lower surface, the cutting edges of the splitting blades being adapted to sequentially engage portions of the sheared length of the wood stock to sequentially split fingerlings from the sheared length.

    摘要： A mold for forming wood flakes into a molded wood flake part including a top mold die and a bottom mold die. The top mold die includes a punch for forming a hole in the part, and the bottom mold die includes a punch receiving aperture. The punch includes a tapered upper portion and a cylindrical lower portion for forming the hole in molded parts of varying thicknesses. The punch includes a tapered upper section defining an upper opening of a first radius in a top surface of the molded part and a cylindrical lower section defining an opening of a second radius in a bottom surface of the molded part. The cylindrical lower portion is sufficiently long that the bottom opening in the hole in each part formed will have the same second radius.
