单板旋切厚度均匀性分析及改进措施

通过对木段旋切时的受力状况进行分析及计算，指出单板厚度不均，即中间薄。两边厚，是旋切时木段产一弯曲挠度所致。通过实验也证实这个结论，并指出旋切时采用防弯压辊是提高单板旋切精度。

Analysis of the Evenness of Venner Peeling Thickness and Improving Measures

Through analysis and calculation of suffer force condition in peeling log, this article pointed out the peeling thickness uneven, that is the outer sides are thick but the middle is thin, is result of the bending deflection in peeling log. The result has been confirmed by experiment. Adopting the anti-bend press roll is the key to improve the precision of veneer peeling and the thickess eveneess of the plywood. Rotary cut machine with anti-bend press roll should be adopted in veneer producing for saving wood resources.
