laminate from logs using thin boards of uniform thickness or cross-sectional area, to maximise use of material

摘要

A laminate of laminae of uniform rectangular cross-section or depths and uniform lengths is derived from a population of logs. The laminate is formed from all the laminae that can be derived from the logs (exclusive only of laminae that are not acceptable regarding cross-section and/or depth). The cross-section of each lamina represents a maximum of one thirtieth of the log cross-section, or the thickness of each lamina represents a maximum of one fifteenth of the small end log diameter.
