  • Patent number: 6336484
    Abstract: The present invention concerns a method that is timesaving, more economical and facilitates the handling and processing of short solid wood planks. Tongue-and-groove joints are machined on the short sides of the short green planks enabling their releasable tight assembly in rows for the seasoning process in the kiln dryer. This temporary attachment between adjacent planks prevents exposition of the short sides to the drying air thus avoiding the usual end grain checking on the latter during kiln drying, and eliminates the need of performing any subsequent machining and trimming steps after the expensive kiln drying step. This process then also improves the saving opportunities by increasing the volume of wood drying capacity and by increasing the production of reusable green wood shavings as opposed to unusable wood shavings following the kiln drying operation.

  • Patent number: 6203255
    Abstract: A router guide apparatus for use in forming rosette designs in a work piece includes a frame having a work surface with a wheel rotatably mounted upon the work surface. The wheel has a plurality of position stops. The rosette design can be formed in a synthetic material (eg. Corian®) and filled with a filler or glue or settable material of a different color to form an inlaid design. The frame includes an adjustable guide for holding and a tracking a router with a cutting blade. The frame includes stops for limiting movement of the router during use. The guide and stops are configured to enable the cutting blade to cut two petals of a rosette design in a single pass. Inserts (fence blocks and/or router filler blocks) can be added to vary the position tracked by the router. The wheel is affixable into multiple angular positions relative to the guide so that multiple cuts can be made at different angular orientations relative to one another.

  • Patent number: 6192949
    Abstract: A method is designed for making bamboo blind slats. The method comprises an initial step in which a selected bamboo stem is split into a plurality of bamboo strips, which are then skinned and disinfected with a sulfur fume for over 12 hours. The disinfected bamboo strips are dried by baking before they are provided with a layer of adhesive. The coated bamboo strips are joined together in conjunction with a pneumatic press to form a rectangular bamboo plate, which is subsequently sliced into a plurality of bamboo slats, with each having a width and a thickness. The bamboo slats are smoothed by grinding and are then covered with a base coating and a face coating which is applied on the base coating. The twice-coated bamboo slats are punched so as to enable them to accommodate the pull cords of a Venetian blind comprising the bamboo slats which are made by the method of the present invention.
