A molded article includes an exterior surface and an opposite interior surface spaced apart by a thickness of the molded article and defining, on opposite sides of the molded article, an inner panel, a main body, and a contoured portion. The contoured portion extends between and interconnects the inner panel and the main body so as to surround the inner panel and be surrounded by the main body. The contoured portion includes contoured corner segments and contoured intermediate segments extending between respective pairs of the contoured corner segments lengthwise. The thickness of the molded article includes a first maximum thickness at the contoured intermediate segments measured from the exterior surface to a closest point of the interior surface, and a second maximum thickness at the contoured corner segments measured from the exterior surface to a closest point of the interior surface that is less than the first maximum thickness.

An apparatus for forming monolithic compressed wood pallets with increased load capacity includes

a storage component having a chamber for collecting the mixture, inside which a first conveyor belt is accommodated for feeding a uniform layer of mixture toward an outlet. The first belt is wound around at least one motorized roller and entrained by it with a feed speed.

The apparatus also includes a pressing component with a lower mold part and an upper mold part between which a receptacle for forming a pallet is provided.

A second conveyor belt is interposed between the storage component and the pressing component. The apparatus further includes a component for modulating at least one among feed speed, the advancement speed, and the translation speed so as to obtain adjustment of quantity of mixture loaded/unloaded on/from upper portion of the second belt along an extension of the mat.

The present invention describes the production of wood panel boards, or the like, in which a surface modifying agent is mixed with a polyol to prepare a stable surface modifying agent polyol composition. The resultant composition is reacted with an isocyanate, and in particular, a polymeric di-isocyanate resin, in the presence of wood chips, fibers or the like, for the production of lignocellulosic based panels, such as oriented strand board (OSB), MDF, HDF and particle board panel products. In use, the surface modifying agent polyol composition is mixed with the polymeric di-isocyanate resin and the resultant mixture is applied to a lignocel-lulosic material, such as wood chips or fibers, immediately prior to hot pressing of the mixture to produce the panels. Sticking of the panels to the metal press belts or press plates typically used during production, is reduced or eliminated.

The invention discloses a bamboo chip integrated material. The bamboo chip integrated material is formed by a plurality of lengthened bamboo chips which are glued and overlaid; each lengthened bamboo chip is formed by a plurality of bamboo chip units which sequentially and continuously mesh and are butted; sharp teeth and grooves are formed in the two ends in the length direction of the bamboo chip units, wherein the sharp tooth of each bamboo chip unit and the groove of the corresponding bamboo sheet unit are matched to form a meshing butt-joint part, and the meshing butt-joint parts of the adjacent lengthened bamboo chips are arranged in a staggered mode; and each bamboo chip unit has a thickness of 4-12 mm and a width of 15-50 mm.

A modular press suitable for use in the manufacture of EWC products may include a plurality of frame modules coupled together and aligned along a feed path axis. Each frame module may have a generally planar body supported on a corresponding pair of bases, an elongate aperture, an upper and a lower platform within the aperture, and a platen between the platforms. Optionally, the ends of the aperture may be curved. A first actuator system may be operable to move the platen from a raised position to an intermediate position, and a second actuator system may be operable to press the platen downwardly from the intermediate position onto a workpiece within the aperture. Some modular presses include conveyor rolls and a third actuator system to raise and lower the conveyor rolls. In some embodiments, the actuator systems may be pneumatic actuator systems. Corresponding methods and systems are also described herein.
