Using rolling pressure on sawmill slabs of Chinese fir (Cunninghamia lanceolata) to form a combing processing blank

Abstract: To probe optimal combing technologies and to design and manufacture the best possible rolls for a combing machine, sawmill slabs of Chinese fir(Cunninghamia lanceolata) were rolled radially without in cross direction. Thickness, moisture content, and compression rate were studied by forming combing processing blank using rolling pressure. Results showed that 1) thickness, moisture content, and compression rate with better rolling pressure technology meant a compression rate and moisture content about 50%. Also, 2) after rolled pressure treatment, the thickness of the slab decreased and the width increased. In addition, 3) after rolled pressure, Chinese fir cells had various distortions, for instance cell compress and a diminished cell cavity, but the cell wall was not destroyed, nevertheless, later most of the cells returned to normal.
