  • 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.

Most logs by nature are radially anisotropic, having wood of higher density and stiffness in their outer portion adjacent the bark than is found in the inner portion. The logs are machined to segregate the denser, stiffer outer wood. A first generally rectangular component is formed from the less dense inner wood. Second generally rectangular components are formed from the stiffer outer wood. Second components are adhesively bonded to at least one edge of the first component, more usually to opposite edges. The stiffer wood is thus specifically placed where it will contribute most effectively to the properties of the product.

  • Patent number: 5944938
    Abstract: The invention is a method of gluing wood using a reactive two component thermosetting adhesive such as a phenol-resorcinol-formaldehyde (PRF) condensation product. One component is first coated on one of the members to be bonded. The second component is then spread directly on top of the first in a manner to minimize mixing; e.g., by spraying. When the mating member to be bonded is placed against the adhesive coated first member and pressure is applied the components are mixed. This begins the curing reaction between the components so that a thermosetting adhesive bond is formed. With selected adhesives very rapid curing times are possible. A preferred adhesive has a first component comprising a PRF resin mixed with a methylene group donor hardener such as paraformaldehyde. The second part is also a PRF resin. No hardener is present in the second part. Instead an oxygen and nitrogen containing heterocycle is used as an accelerator. Morpholine is a preferred compound.

  • Patent number: 5881786
    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: 5607265
    Abstract: A device to change the rotation of a shaft such as in an electric hand drill to the reciprocating motion necessary to power a saw blade. The reciprocating attachment has a grooved shaft and saw blade holder connected by a bearing all of which are contained in a housing. As the grooved shaft is rotated the shape of the groove in the grooved shaft causes the saw blade holder to move in a reciprocal manner in a groove in the housing. This provides the motion necessary to use a hand drill to saw an object. Alternative versions of the device include the widening of the groove in the grooved shaft with the saw blade holder having a holder pin and an end retained in a holder groove to cause the reciprocal motion. In addition, an inclined disk may be mounted on the rotating disk shaft to engage the saw blade holder slot to cause the reciprocal motion.

  • Patent number: 5411066
    Abstract: A method of producing a veneer having a given thickness requires cutting of a stock material by a mechanism including a rotary lathe blade and a nose bar. The nose bar is arranged at the outer periphery of the stock material in the vicinity of the tip of the rotary lathe blade, such that the spacing between the tip of the nose bar and the tip of the rotary lathe blade in a horizontal direction is 20 to 30% smaller than the thickness of the desired veneer to be cut. The stock material is cut by rotating the stock material by a spindle which chucks the end faces of the stock material at opposite ends thereof. A backup roller rotated by the rotation of the stock material constantly biases the stock material toward the nose bar and is positioned on the outer periphery of the stock material in a position diametrically opposite to the rotary lathe blade.
