摘要： The invention provides a bandmill having an endless loop of bandsaw blade which is automatically strained to a desired tension, and automatically driven at an accurate location or tracking position. The bandmill runs on a pair of spaced co-planar wheels, which are forced longitudinally apart to apply strain to the bandsaw. Actual saw strain is automatically detected by a force transducer within the strain mechanism, and the actual saw strain is automatically compared electronically with a desired saw strain. A servo-controller automatically adjusts distance between the wheels to vary force therebetween so that actual saw strain is varied to approach the desired saw strain. Also, actual tracking of the saw blade relative to the wheels is automatically sensed by sensors located adjacent the edge of the saw blade. The actual tracking of the saw blade is compared electronically relative to a desired tracking position, and tilt of a tiltable wheel is automatically adjusted so that actual tracking of the saw on the wheels is varied to approach the desired tracking position. Alternatively, a visual display of actual tracking accuracy can be obtained, so as to permit manual adjustment of the tiltable wheel to correct inaccurate tracking.
摘要翻译：本发明提供了一种具有无限循环的带锯刀片的带式磨床，其自动地变形到期望的张力，并且在精确的位置或跟踪位置自动地驱动。带式跑车在一对间隔的共面轮上运行，这些轮被强制纵向分开以对带锯施加应变。实际锯应变由应变机构内的力传感器自动检测，并且实际的锯应变自动地与所需的锯应变电子地进行比较。伺服控制器自动调节车轮之间的距离以改变其间的力，使实际的锯应变变化以接近所需的锯应变。此外，锯片相对于车轮的实际跟踪由位于锯片边缘附近的传感器自动检测。相对于期望的跟踪位置对锯片的实际跟踪进行电子比较，并且自动调整可倾斜轮的倾斜，使得轮上的锯的实际跟踪被改变以接近期望的跟踪位置。或者，可以获得实际跟踪精度的视觉显示，以便允许手动调节可倾斜轮以校正不准确的跟踪。

摘要： A bandmill has first and second wheels and an endless saw blade trained about the wheels. The wheels are mounted to rotate about respective axes which lie in a common plane, but the first wheel is adjustable in position relative to the second wheel with respect to both its distance from the second wheel and its orientation relative to the second wheel. A tensioning mechanism is effective to force the first wheel away from the second wheel, while maintaining the axes of rotation of the two wheels substantially parallel, in response to a signal which is provided by a load cell and represents the tension in the saw blade. A wheel tilt mechanism is effective to adjust the angular position of the first wheel relative to the second wheel in response to a signal indicating the path followed by the saw blade, for maintaining the blade on a proper path.

摘要： In an automatic sawmill, logs are first sawn horizontally into pieces that are respectively deposited flat side down on a bed plate and conveyed through multiple, close spaced horizontal bandsaws located above the bed plate. Sawn cants are positioned by clamps to have their waney edges removed by a flying saw after clamp retraction.

摘要： An end-dogging log carriage including a first dog assembly with a first dog member rotatably mounted thereon and a second dog assembly with a second dog member rotatably mounted thereon. A log is supported solely by the first and second dog members engaging opposite ends of the log. At least one of the dog members is movable horizontally and vertically to orient the log to a desired position for sawing the log. There may be an indexing device operatively connected to one of the dog members through a clutch. The log may be rotated for scanning when the clutch is disengaged. The indexing device and the clutch are engaged after the log is oriented in a rotational position for a first sawing operation. The clutch is left engaged and the indexing device is employed to rotate the log through the required angle for the next sawing operation.

摘要： Intermediate dogging device to limit lateral deflection of a log held in end dogging log carriage. When a log is machined, residual stresses within the wood, weight of the wood, and sawing forces tend to deflect unsupported portions of the log, reducing cut accuracy. An intermediate dog is mounted on carriage between end dogs generally adjacent central plane containing feed axis. The intermediate dog extends from carriage and engages the log extending between the end dogs to reduce movement of log relative to carriage.
