Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
In a method for forming a veneer core block for a plywood wherein thin wood sheets are cut to form a plurality of green veneer strips having a maximum effective width, the method comprising the steps of juxtaposing the green veneer strips such that said veneer strips are closely contacted side by side, forming inclined slits on the surface of said green veneer strips, embedding strings in said slits to temporarily connect the closely contacted green veneer strips, and supplying and adhesive into said slits.
Claim 2
Dependent Claim
85 words
In a method for forming a veneer core block for a plywood wherein thin wood sheets are cut to form a plurality of green veneer strips having a maximum effective width, the method comprising the steps of juxtaposing the green veneer strips such that said veneer strips are closely contacted side by side, forming inclined slits on the surface of said green veneer strips, embedding strings in said slits to temporarily connect the closely contacted green veneer strips, and supplying and adhesive into said slits.
Claim 3
Dependent Claim
22 words
A method as claimed in claim 1, wherein said strings are embedded in said inclined slits immediately after said slits are formed.
Claim 4
Dependent Claim
23 words
A method as claimed in claim 1, wherein said strings are coated with said adhesive before said strings are embedded in said slits.
Claim 5
Dependent Claim
33 words
A method as claimed in claim 1, wherein said adhesive has a water setting characteristic to permit an immediate hardening of the adhesive by reaction with water contained within said green veneer strips.
Claim 6
Dependent Claim
19 words
A method as claimed in claim 1, wherein the veneer core blocks are stacked before the adhesive is hardened.
Claim 7
Dependent Claim
49 words
A veneer core block for a plywood, comprising a plurality of green veneer strips contacted closely side by side, said green veneer strips having a plurality of inclined slits and strings with an adhesive within said slits, thereby connecting said green veneer strips to form a veneer core block.
Claim 8
Dependent Claim
49 words
A veneer core block for a plywood, comprising a plurality of green veneer strips contacted closely side by side, said green veneer strips having a plurality of inclined slits and strings with an adhesive within said slits, thereby connecting said green veneer strips to form a veneer core block.
Claim 9
Dependent Claim
29 words
A veneer core block for a plywood as claimed in claim 5, said slits are inclined at about 20° with respect to the surface of said green veneer strips.
Claim 10
Dependent Claim
23 words
A veneer core block for a plywood as claimed in claim 7, wherein said slits are inclined in different directions from each other.
