    • A wood veneer lathe that includes a sensor carried by the nose bar and co-acting with the peeling knife to detect and provide an output signal in response to and proportioned to deviations from a predetermined spacing of the nose bar and knife relative to one another. The sensor is located downstream from the point of contact of the nose bar with the block at a position opposite a flate face of the knife and adjacent the latters cutting edge. A particular veneer lathe is disclosed that includes electrohydraulic linear actuators with feedback control means for adjustably positioning the peeling knife. Signals from the sensor, detecting deviations of the peeling knife from its fixed setting, are analyzed by a computer and the latter controls actuators to make suitable knife position adjustments to control the veneer thickness.
    • 一种木材单板车床,其包括由鼻杆承载并与剥皮刀共同作用的传感器,以响应于鼻梁和刀相对于彼此的预定间隔的偏差并且与之成比例地检测并提供输出信号。 传感器位于与杆的接触点的下游,与刀块的与刀片的平面相对的位置处,与刀片的切削刃相邻。 公开了一种特定的单板车床,其包括具有用于可调整地定位剥皮刀的反馈控制装置的电动液压线性致动器。 传感器的信号,通过计算机分析检测剥离刀与其固定设置的偏差,后者控制致动器进行适当的刀位调节,以控制胶合板的厚度。

    • A wood incising roller where the teeth are formed by grooves in the roller surface and where some of such grooves cross others. Each cutting tooth has a knife-like cutting edge of finite length that is in one instance perpendicular to the axis of rotation of the roller and in another instance parallel to such axis. The grooves can be formed by machine cutting, either turning or grinding or by being molded in the surface and then shaped by a grinding operation. At least some grooves preferrably spiral about the roller. The pattern of cutting teeth and shape are determined by such variable parameters as pitch, number of thread starts, angle of cutter, depth of cut and lead angle. An incisor for lumber or veneer consists of two rollers at least one of which is as described in the forgoing. The grooves can be filled or partially filled with an elastic compressible material. The incising roller of the foregoing also is used in combination with a veneer lathe.
    • 一种木材切割辊,其中齿由辊表面中的凹槽形成,并且其中一些这样的沟槽与其他的沟槽交叉。 每个切割齿具有有限长度的刀形切割边缘,其在一个实例中垂直于滚子的旋转轴线,并且在另一个实例中平行于该轴线。 槽可以通过机械切割,转动或研磨,或通过模制在表面中,然后通过研磨操作成形而形成。 至少一些槽优选地围绕辊螺旋。 切割牙齿和形状的图案由螺距,螺纹开始次数,刀具角度,切削深度和导程角等可变参数决定。 木材或单板的门牙由两个辊组成,其中至少一个如上述所述。 凹槽可以用弹性可压缩材料填充或部分填充。 上述的切割辊也与单板车床结合使用。
