Abstract

Abstract A method and apparatus for scanning veneer logs or blocks to obtain the maximum amount of veneer from each block. The method includes the positioning of a veneer block along a predetermined reference axis, electronically scanning the block along one side to determine its profile dimensions with respect to a first plane intersecting the ends of the block, computing the true center line of the block in the first plane, and repositioning the block along that true center line. The block is then rotated by a predetermined angle, such as 90*, and rescanned along a second side to determine its profile dimensions with respect to a second plane intersecting the ends of the block. The true center line of the block in the second plane is then computed and the block is repositioned along the true center line in that plane prior to processing by a rotary veneer lathe. A particular scanning and processing apparatus is disclosed for practicing the steps of the method in processing veneer blocks of different diameters into veneer.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 153 words
A method of processing a veneer log to prepare it for the loading of a veneer lathe comprising the steps of positioning the log in a reference position, scanning the log along a side thereof to determine its profile dimensions in a first plane intersecting the ends of the log, plotting the center line of the widest paral-lelogram that can be superimposed within the profile dimensions of the log in said first plane, repositioning the log with said center line parallel to an index line of said veneer lathe, rescanning the repositioned log along another side to determine its profile dimension in a second plane intersecting the eNds of the log, plotting the center line of the widest parallelogram that can be superimposed within the profile dimensions of the log in said second plane, and repositioning the log with said second mentioned center line parallel to an index line of said veneer lathe.
Claim 2
Independent Claim 153 words
A method of processing a veneer log to prepare it for the loading of a veneer lathe comprising the steps of positioning the log in a reference position, scanning the log along a side thereof to determine its profile dimensions in a first plane intersecting the ends of the log, plotting the center line of the widest paral-lelogram that can be superimposed within the profile dimensions of the log in said first plane, repositioning the log with said center line parallel to an index line of said veneer lathe, rescanning the repositioned log along another side to determine its profile dimension in a second plane intersecting the eNds of the log, plotting the center line of the widest parallelogram that can be superimposed within the profile dimensions of the log in said second plane, and repositioning the log with said second mentioned center line parallel to an index line of said veneer lathe.
Claim 3
Dependent Claim 24 words
The method of claim 1, wherein said scanning and rescanning are carried out along first and second planes that intersect at a right angle.
Claim 4
Independent Claim 88 words
A method of processing a log to prepare it for the loading of a veneer lathe comprising the steps of positioning the log in a reference position, scanning the log from at least two sides to determine profile dimensions in two planes intersecting the ends of the log, plotting the center lines of the widest parallelograms that can be superimposed within the profile dimensions of the log in said two planes, and repositioning the log with these center lines parallel to an index line of said veneer lathe.
Claim 5
Independent Claim 88 words
A method of processing a log to prepare it for the loading of a veneer lathe comprising the steps of positioning the log in a reference position, scanning the log from at least two sides to determine profile dimensions in two planes intersecting the ends of the log, plotting the center lines of the widest parallelograms that can be superimposed within the profile dimensions of the log in said two planes, and repositioning the log with these center lines parallel to an index line of said veneer lathe.
Claim 6
Dependent Claim 32 words
The method of claim 1, wherein said scanning and rescanning are performed at the same scanning station, and the log is rotated after its first-mentioned repositioning to prepare it for its rescanning.
