Patent ID: 7347234

Claim:
A method for optimizing the value of yield in veneer peeling, said method comprising: a) scanning the contour of a log to be peeled as measurement values; b) determining a log specification for the log on said scanned contour measurement values; c) inputting said scanned contour measurement values into a data processing device to define a virtual log; d) selecting a simulation turning axis on said log specification; e) carrying out a first data processing device simulated peeling using said turning axis and said scanned log measurement values for the data processing device to simulate a peeled veneer web; f) defining at least two veneer quality grades to indicate respective sections on said simulated peeled veneer web; g) determining an area of each section having a quality of one of said at least two veneer quality grades on said simulated peeled veneer web; h) giving a value for each of the at least two quality grades; i) defining a total yield value for said simulated peeled veneer web; j) selecting an alternative simulation turning axis on said log specification; k) carrying out a subsequent data processing device simulated peeling using said alternative simulation axis and said scanned log measurement values for the data processing device to simulate a subsequent peeled veneer web; l) performing steps f) through i); m) repeating steps j) through l); n) selecting a turning axis for an actual veneer peeling giving the highest total yield value; and o) carrying out said actual veneer peeling from said actual log using said selected turning axis.
