Publication number: 20020195169Abstract: A method for fabricating bamboo blind slats is disclosed. The steps include splitting a selected bamboo stem into several bamboo strips, removing the skins and joints from the bamboo strips before being disinfected and dried and then trimming them to fine bamboo strips. Further at least two bamboo strips are indented or truncated to joint with the corresponding ends, and then is trimmed to a fine jointed bamboo strip. A bamboo plate is obtained by joining fine jointed bamboo strips and/or the fine bamboo strips together in conjunction with a pneumatic press, and then is trimmed and polished. After slicing the bamboo plate into several bamboo slats, the bamboo slats need to be polished before covering a base coating, polished again before covering a face coating. Finally the bamboo slats are punched two cord holes to be used for making a Venetian blind.Type: ApplicationFiled: June 26, 2001Publication date: December 26, 2002Inventor: Feng-Yuan chen

Patent number: 6336484Abstract: 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.Type: GrantFiled: June 1, 2000Date of Patent: January 8, 2002Inventor: Gilles Grenier

Patent number: 5163491Abstract: Improved methods of fabricating at least partially curved staircases include a first method in which preformed step structures have treads with curved slots formed in the underside of the ends which define a path for insertion of top edge segments of thin starter strips. The slots are collectively configured to laterally deflect the inserted starter strips in a manner longitudinally conforming them to at least partially curved paths of the overall stringer structures in the completed staircase. The stringers are then laterally built up and completed by securing reinforcing structures to the side surfaces of the laterally deflected strips. A second method uses preformed cooperating treads and risers themselves as a form which defines an at least partially curved path for the stringers.Type: GrantFiled: November 27, 1991Date of Patent: November 17, 1992Inventor: Lynn H. Smith

Patent number: 5137066Abstract: A dovetail jointing press for the manufacture of dovetail joints of boards, having respective dovetailings at their faces that are pasted with glue, is provided. The press comprises two tables that are disposed on common tracks and receive continuously fed boards. The tables are slidable on the tracks towards one another and away from one another via respective working cylinders. The respective presses that are disposed above each one of the tables are closed by working cylinders and released when the tables are moved away from one another. All the moving functions of the dovetail jointing press may be performed by working cylinders or by threaded spindles driven by electric motors. Computer programming may be used to coordinate the individual movements, so that the press may be operated automatically.Type: GrantFiled: January 11, 1991Date of Patent: August 11, 1992Inventor: Erwin Dimter

Patent number: 5115609Abstract: The method of converting logs involves cutting each log longitudinally and diametrically at right angles into equal quarter-log segments, the rearranging the quarter-logs so that the arcuate surfaces of the segments face inwardly toward each other, while their cut flat surfaces are positioned to form a rectangle in cross-section. The segments so positioned may be joined together as such, rigid foam plastic insulation may be introduced into the space remaining between the segments, or support bracing and other insulation may take the place of the rigid foam. The resultant converted logs may be used as beams, joists or bearing-wall members; devices for aligning, registering and sealing the converted logs together are provided.Type: GrantFiled: July 3, 1991Date of Patent: May 26, 1992Inventor: Peter Sing

Patent number: 5114265Abstract: An interlocking joint for joining two panels together has curved jigsaw shaped indents and protrusions on edges of both panels that fit together and cannot pull apart. The indents and protrusions are cut by a router with a straight sided cutter. A template is provided for guiding a bushing on a cutter shaft of a router and the template takes into account the bushing having a larger diameter than the cutter. There is also a jig provided that has fingers that are asembled to cut out the interlocking joint with a router.Type: GrantFiled: April 15, 1991Date of Patent: May 19, 1992Inventor: Kenneth M. Grisley

Patent number: 5090462Abstract: A dovetail cutting device and a method for the manufacture of dovetailings on the faces or ends of boards that are to be jointed face to face, in a continuous manner or individually, is provided. The dovetail cutting device comprises two tables that are facing one another and are slidable relative to one another for receiving and transporting boards that are stacked on edge. A pivotable abutment for aligning the boards when the tables are moved toward one another is disposed at each one of the tables on a side facing one another. A dovetail cutter is mounted between the tables in a slidable manner in a direction transverse to the direction of movement of the tables. It comprises, for example, a circular saw for cutting to size the faces or ends of the boards, a cutter for cutting the dovetailings, and a pasting device for providing the dovetailings with glue. Hydraulic working cylinders are provided for moving the tables and the dovetail cutter.Type: GrantFiled: January 11, 1991Date of Patent: February 25, 1992Inventor: Erwin Dimter

Patent number: RE33703Abstract: A method of producing a laminated plate comprises the steps of (a) preparing a pair of blocks in each of which a plurality of plate elements overlap each other in an inclined position such that the plate elements have one end portions appearing stepwise at predetermined intervals on one surface of the block and the other end portions appearing flat on the other surface of the block, and (b) interlocking and bonding the two blocks to each other such that the one end portions of the plate elements in one of the blocks and the one end portions of the plate elements in the other block oppose each other in a predetermined positional relationship, whereby a laminated plate opposite major surfaces of which are flat is produced.Type: GrantFiled: May 15, 1989Date of Patent: October 1, 1991Assignee: Meinan Machinery Works Inc.Inventor: Hidenori Hasegawa

Patent number: RE36153Abstract: Converted log structural products are produced from conventionally unusable or marginally useful sections of logs transversely cut into suitable lengths and then cut longitudinally by perpendicular cuts into log parts of either right-angled sector or right triangle cross-section. Four log parts matching in size and shape, and positioned so that their right angles form the corners of a rectangle, are assembled into a converted log, the interior space between the four log parts being filled selectively with braces, supports, insulation, concrete for various applications.Type: GrantFiled: March 24, 1995Date of Patent: March 23, 1999Inventor: Peter Sing
