  • Patent number: 7147741
    Abstract: The fundamental technique of the method for making cellular cores is to make stacks of components which are configured such that cutting slices off the stacks produces cellular cores and, when needed, components used in stacks used to produce cellular cores. One of the basic components used in the stacks is termed a ribbed ply which is a ply (thin sheet of material such as wood) with a number of ribs (long thin strips of material such as wood) attached to the ply, parallel to each other. The spaces between the ribs are filled with filler material such as foam plastic, and the cells in the cellular core are filled with the filler material. The filler material is introduced as layers of the material stacked alternately with plies and adhesively attached. Slices of such a stack, sliced parallel to the grain of the plies (if wood) are called ribbed fillers. Stacking ribbed fillers and plies produces a stack having a cross section which, when sliced, produces filled cell cellular cores.

    Abstract: The invention is a method for producing flitches prepared from roundwood logs, a method for the manufacture of wood slices or slats from the flitches, and methods of combining the strips into composite lumber products. The methods are based in part on the concept of preparing flitches that retain the sweep or natural longitudinal curvature of the log and slicing or sawing around the sweep to prepare the slats for further conversion into composite lumber products. An opening cut is made in the log essentially following or parallel to the curve of any sweep to divide it into two approximately equal volume pieces. An opposing surfaces is machined parallel to the surface generated by the opening cut to produce a flitch. The flitches are then flattened so that the sweep curvature is made planar. They are then sliced or sawn parallel to the now planar surface to produce slats. The natural surface of the log is preferably retained on the sides of the flitches.

  • Patent number: 5791117
    Abstract: A method for making substrate-supported slatted panels which consists of first cutting each slat to the appropriate size required to form the panel. The slats are placed face down on a flat support and are assembled according to the design of the intended panel using a frame to keep the slats together, if necessary. Multiple uniform layers of contact adhesive are then progressively applied to the back of the slat panel so formed, thereby producing a flexible continuous sheet of adhesive backing the panel. At least one uniform layer of adhesive is also applied to a rigid substrate of dimensions appropriate to support the panel. When the adhesive is dry and ready for contact, the substrate is lifted and placed over the intended location on the slat panel using a series of spacers to prevent contact. Finally, the spacers are sequentially removed permitting contact and the formation of a rigid slatted panel.

  • Patent number: 5679191
    Abstract: An improved method for fabricating trailer length platform flooring from wooden blanks comprises selecting kiln dried lumber having a predetermined width and thickness and exhibiting preestablished strength and durability characteristics. The lumber is inspected for the presence of unacceptable defects and the defects are cut out to form defect-free blanks of varying lengths. The blanks are aligned successively in spaced end to end relationship with the trailing end of one blank facing the leading end of the next successive blank. The facing ends are then machined with interlockable vertically extending fingers, adhesive is applied to at least one of the ends, and the fingers are pressed together with a predetermined pressure to bond the ends of the blanks together. These steps are repeated resulting in a continuously growing composite plank comprised of end-to-end joined blanks.

  • Patent number: 5560409
    Abstract: A method of resawing elongated radially sawn segments of timber so that bsawn boards are produced. Said wedges are sawn with the desired angle between the radial faces and are resawn so that the growth rings of the tree are basically parallel to the broad backsawn faces. The flared radial edges of the boards indicate the growth ring orientation and therefore the cupping tendency and the direction of bow. This enables a greater degree of consistency in the manufacturing process over conventional methods. Said backsawn boards can be used individually as conventional boards with the mentioned advantages or can be laminated together to make a range of laminates that balance or use the bowing and cupping tendency of backsawn timber.

  • Patent number: 5183090
    Abstract: This relates to a panel of the type which includes a core covered by veneer and generally relates to a furniture panel. Such panels have a front edge which is contoured and is generally rounded. The panel in question has a generally rounded edge which terminates at the bottom thereof in a low radius portion, i.e., on the order of 2 mm. Because of this very low radius it is virtually impossible to take a single sheet of veneer and wrap it around such a radius. The problem is solved by using two separate veneers, an upper and a lower, and where the low radius edge portion is, machining a channel in the core and filling the channel with a projecting plug which then has the projecting portion thereof machined to provide a smooth continuous surface. Additionally, in order that there may be no demarcation of materials, the plug is formed of the same material as the veneers.

  • Patent number: 4536427
    Abstract: A light-weight contourable core of high strength for inclusion in boat hulls in which the core is sandwiched between facing sheets of resin-reinforced fiberglass. The core is formed by a planar array of block-like modules made of end-grain balsa wood or other material having acceptable properties whose adjacent edges are held together by flexible adhesive joints that have a short elastic limit, such that when the planar core is pressed against a contoured surface for lamination thereto, the resultant stresses cause the joints to stretch beyond their elastic limit to an extent necessary to permit the modules to conform to this surface. There is no spring back when the pressure is released, and the modules, therefore, maintain their conformed positions.
