摘要： A cord burying apparatus for a veneer sheet is provided. The apparatus comprises a cord burying knife and a piercing element having a plurality of piercing members thereon and provided on one side of the cord burying knife in axial juxtaposition therewith relative to the log. The cord burying knife has an edge facing upstream with respect to the log rotation to come into a cutting engagement with the log. The piercing members on the piercing element also come into cutting engagement with the log to positively move the log past the knife. The provision of the piercing element facilitates cutting operations of a log having rotten portions.

摘要： A method of reeling and unreeling a reinforced veneer sheet is provided. A veneer sheet peeled off from a log on the veneer lathe is subjected to a reinforcing step, in which an elongated cut is formed on one side of the sheet across the grain and a length of cord is embedded in it. In a reeling operation, the reinforced veneer sheet is wound onto the reel with its cut side facing radially outward. In an unreeling operation, on the other hand, the sheet is unwound from the roll with its cut side facing downward. This method prevents the embedded cord from slipping out of the engagement with the elongated cut during the reeling and unreeling operations.

摘要： A veneer lathe in which a log is rotatably supported, and powered endless chain members having sharpened projections on their outer side are employed to rotatably drive the log. A knife is provided at the log surface so that the log is cut in a circumferential direction as the knife moves toward the longitudinal axis of the log and the log rotates. Log pressure means are provided to press the log surface adjacent the knife edge, and a conventional transport mechanism moves the assembly of the endless chain members, the knife, and the log pressure means toward the longitudinal axis of the log in synchronization with the log rotation so that a veneer is continuously cut from the log.

摘要： A method for preparing a laminate including pressing a heater against the upper and lower surfaces of a veneer during which an inner portion of the veneer in the thickness direction is dried to the smallest extend then the surfaces so that a water content of the inner portion is kept higher than that of the surfaces, dividing the veneer in terms of its thickness into two counter veneers, placing a ligneous board between the counter veneers using an adhesive so that the surfaces resulting from the diving are disposed as outer surfaces, and pressing a heater against the outer surfaces to effect bonding of the counter veneers and the ligneous board. The period of time for pressing the heater against the upper and lower surfaces of the veneer is such that the surfaces and a region in a vicinity thereof, against which the heaters have been pressed, are dried to a water content of between about 5% and about 20% while the inner portion of the veneer in the thickness direction is dried to a water content higher than the fiber saturation point at which contraction begins.

摘要： An improved veneer lathe which cuts sheets of veneer from a turned log. A torque is applied to the log both by way of the spindle chuck holding its axial ends and by way of its outer periphery. During the cutting operation, the primary cause of log rotation is designed to be an external force applied to the log periphery by using an idling mechanism including a torque limiter, an over-running clutch, etc.

摘要： A method of mending a veneer sheet having a defective portions is provided. An imcomplete veneer sheet and a sheet of mending material is laid one on top of the other. They are cut through by a single stroke of a annular cutting tool such that the defective portion of the veneer sheet is cut off whereas a plug having a same size and shape as the cut-off defective portion is cut out. They are retained in the annular cutting tool until the plug is shifted into a plane in which the veneer sheet extends. At the same time, the cut-off defective portion is removed from the veneer sheet. Then, when the cutting tool is removed from the sheets, a mended veneer sheet results.Another method is also provided. A plurality of plugs are cut out from a sheet of mending material by repeatedly cutting through it by a single annular cutting tool. The cut-out plugs are retained in the annular tool. Then, an incomplete veneer sheet is cut through by the tool to cut off a defective portion from the veneer sheet while the plugs retained in the tool pushed farther into it. However, a plug in contact with the cut-off defective portion is pushed toward the plane in which the veneer sheet extends. As a result, the defective portion is routed out. When the annular cutting tool is removed from the sheet, the mended veneer sheet results. This can be repeated until the plugs run out.
摘要翻译： 提供了修补具有缺陷部分的单板的方法。 不完整的单板和一块修补材料被放置在另一个之上。 它们通过环形切割工具的单次冲程被切割，使得薄板的缺陷部分被切断，而切除具有与截止缺陷部分相同的尺寸和形状的插头。 它们被保持在环形切割工具中，直到插头移动到单板延伸的平面内。 同时，切断缺陷部分从单板剥离。 然后，当切割工具从纸张上取出时，会产生修补的单板。 还提供了另一种方法。 通过用单个环形切割工具反复切割多个插头，从一片修补材料切出多个插头。 切口塞子保持在环形工具中。 然后，通过该工具切割不完整的单板，以便在保持在工具中的插头进一步推入其中时，从薄板片上切断缺陷部分。 然而，与截止缺陷部接触的插头被推向薄板延伸的平面。 结果，故障部分被路由输出。 当环形切割工具从片材上移除时，修补的单板就可以得到。 这可以重复，直到插头用尽。
