摘要： A pressure bar of the fixed type for veneer cutting is heated to reduce frictional drag against the wood surface. In the preferred form, the pressure bar is contoured having a tip with a relatively small radius of curvature and a face, in advance of the tip, which has a relatively large radius of curvature. The combination of a heated contoured pressure bar provides performance comparable with that of a roller bar in terms of roughness and friction, but at significantly reduced cost.

摘要： 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.

摘要： A system of drying veneer sheets for manufacturing wood products such as plywood, measures the moisture content of the sheets and controls drying to a predetermined moisture content. By drying veneer sheets to the predetermined moisture content, avoids excessive drying to ensure all sheets are below the 11% moisture content level. A process of drying comprises incising a veneer sheet, sensing the moisture content of the incised veneer sheet, steam drying the sheet under pressure and controlling the drying based on the sensed moisture content of the veneer sheet, to dry the sheet to the predetermined moisture content.
摘要翻译：一种用于制造诸如胶合板的木制品的单板的干燥系统，测量片材的水分含量并控制干燥至预定的水分含量。通过将胶合板干燥至预定的水分含量，避免过度干燥以确保所有的纸张都低于11％的含水量。干燥过程包括切割单板，感测切割的薄板片材的水分含量，在压力下蒸汽干燥薄片并基于感测到的薄板片材的含水量控制干燥，将片材干燥至预定的水分含量。

摘要： 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.
摘要翻译：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。

摘要： A chuck for a veneer lathe is provided, which has a generally wedge-shaped lug with a first, corrugated face, preferably of a stepped configuration. Such a chuck reduces the tendency of a lug to split during processing, and thus reduces chuck spin-out and resultant wastage.
