Abstract
Abstract A new artificial veneer resembling expensive natural wood veneers can be manufactured by a new method from an inexpensive raw log, wherein a wood-meal containing veneer is first obtained by slicing in quartersawn grain direction a primary artificial flitch of many material veneers of the inexpensive raw log stacked and bonded with a wood-meal layer interposed between them, and many of the wood-meal containing veneers are stacked and bonded, with the material veneers alternately interposed as they stand or as further processed, into a secondary curved artificial flitch, which is sliced in flatsawn grain direction into the new artificial veneers presenting a grain pattern similar to that of the expensive wood with minutely raised and recessed uneven surface at simulated porous zones by the wood-meal containing veneers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
224 words
A method of manufacturing artificial veneers comprising the steps of preparing material veneers cut out of at least a raw log, depositing wood meal onto respective said material veneers with an adhesive interposed, preparing a primary artificial flitch by stacking, pressing and collecting a plurality of said material veneers having said wood meal adhered such that said primary flitch comprises alternating layers of material veneers and wood meal, slicing said primary artificial flitch in its quartersawn grain direction by a cutting edge oriented generally perpendicularly to the planes of said layers to obtain particle-containing veneers, preparing a secondary artificial flitch by stacking, pressing and collecting with an adhesive interposed a combination of a plurality of said particle-containing veneers with additional ones of said material veneers such that said additional material veneers are disposed in alternating relationship relative to said particle-containing veneers and are oriented generally perpendicularly to the planes of said layers of said particle-containing veneers, said additional material veneers being provided in said secondary flitch at a ratio of at least 1:1 relative to said particle-containing veneers, and slicing said secondary artificial flitch in its flatsawn grain direction by a cutting edge oriented generally perpendicularly to the planes of said layers and traveling through said secondary flitch in a direction oriented at an angle relative to the planes of said additional material veneers.
Claim 2
Independent Claim
224 words
A method of manufacturing artificial veneers comprising the steps of preparing material veneers cut out of at least a raw log, depositing wood meal onto respective said material veneers with an adhesive interposed, preparing a primary artificial flitch by stacking, pressing and collecting a plurality of said material veneers having said wood meal adhered such that said primary flitch comprises alternating layers of material veneers and wood meal, slicing said primary artificial flitch in its quartersawn grain direction by a cutting edge oriented generally perpendicularly to the planes of said layers to obtain particle-containing veneers, preparing a secondary artificial flitch by stacking, pressing and collecting with an adhesive interposed a combination of a plurality of said particle-containing veneers with additional ones of said material veneers such that said additional material veneers are disposed in alternating relationship relative to said particle-containing veneers and are oriented generally perpendicularly to the planes of said layers of said particle-containing veneers, said additional material veneers being provided in said secondary flitch at a ratio of at least 1:1 relative to said particle-containing veneers, and slicing said secondary artificial flitch in its flatsawn grain direction by a cutting edge oriented generally perpendicularly to the planes of said layers and traveling through said secondary flitch in a direction oriented at an angle relative to the planes of said additional material veneers.
Claim 3
Dependent Claim
22 words
A method according to claim 1 wherein said adhesive for depositing said wood meal onto said material veneers is a foam adhesive.
Claim 4
Dependent Claim
15 words
A method according to claim 2 wherein said foam adhesive is of an urethane resin.
Claim 5
Dependent Claim
35 words
A method according to claim 1 wherein said material veneers employed for preparing said secondary artificial flitch are made of the same raw log as said material veneers to which said wood meal is deposited.
Claim 6
Dependent Claim
48 words
A method according to claim 1 wherein said material veneers employed for preparing said secondary artificial flitch are collected veneers obtained by collecting a plurality of said material veneers stacked and pressed with an adhesive interposed into another primary artificial flitch and slicing said another primary artificial flitch.
Claim 7
Dependent Claim
63 words
A method according to claim 1 wherein said material veneers employed for preparing said secondary artificial flitch are fragment-containing veneers obtained by depositing a plurality of elongate fragmentary members onto said material veneers, collecting a plurality of said material veneers having said fragmentary members stacked and pressed with a binder interposed into another primary artificial flitch and then slicing said another primary flitch.
Claim 8
Dependent Claim
13 words
A method according to claim 6 wherein said fragmentary member is of wood.
