Abstract: A method for predicting the remaining service life of a saw band in a bandsaw machine, in which a behavior or properties of the saw band clamped in the sawing machine are monitored by at least one sensor during operation of the sawing machine. Changes in the behavior or in properties of the saw band over time established on the basis of measurement signals of the sensor device are used for making a prediction about the time at which a band will break. The behavior or properties of the saw band are indirectly monitored using the at least one sensor device by way of detecting changes to components of the sawing machine which are operatively connected to the saw band.

Abstract: A sawmill comprising first and second clamp members for clampingly engaging opposite sides of a log or log cant. A trolley includes the second clamp member. For moving the trolley cross-wise of the sawmill base, a threaded rotatable rod, to which a handle is attached, extends cross-wise of the base. The trolley includes a pair of walls which have a pair of aligned vertically oblong apertures respectively for receiving the rod. A half nut is fixedly attached to a bottom of one of the apertures and has threads which mate with threads on the rod so that the rod can threadedly engage the half nut. The apertures are sized such that the trolley can be tilted so that the threads of the rod and the half nut can be disengaged and the trolley slid along the rod to an approximate position for clampingly engaging the second clamp member to the log or log cant, then, with the trolley positioned upright and the threads of the rod and the half nut re-engaged, the handle can be turned to apply clamping force by the second clamp member to the log or log cant.

Abstract: A band saw is disclosed that includes a frame, a guide wheel, and a blade disposed around the guide wheel. A guide wheel chassis can be movably disposed on the frame, the guide wheel rotatably disposed on the guide wheel chassis. The band saw can include a blade tension adjustment assembly including a tensioning motor, wherein operation of the tensioning motor produces movement of the guide wheel chassis and the guide wheel relative to the frame to adjust the tension of the blade. A tension gauge can be positioned to determine a tension in the blade, and a controller can be communicated with the tensioning motor and the tension gauge, the controller operable to receive tension data from the tension gauge and control operation of the tensioning motor based on the tension data to control the tension of the blade.

Abstract: A band saw blade sensor and control system to sense and control saw blade deviation of a continuous, flexible metal saw blade driven around a pair of pulleys. A pair of spaced proximity inductive sensors is positioned adjacent to a side of the saw blade in order to detect blade deviation during operation. A controller mechanism receives input from each of the pair of inductive sensors in order to control and adjust band tension on the blade, and in order to control and adjust blade force on a work piece.

Abstract: The present invention relates to a belt brake for a band saw such as a band saw on a sawmill utilized for sawing lumber. The belt brake provides added safety by stopping the blade of the band saw when the operator deactivates the band saw, for example, by turning the band saw off or operating the band saw clutch. The belt brake activation may be synchronized with the band saw's clutch mechanism.

Abstract: A portable bandsaw mill including an elongated saw frame, a saw carriage for traversing the saw frame and a blade unit vertically adjustably mounted on the saw carriage. A bandsaw blade provided on the blade unit is operably engaged by a hydraulic blade drive motor. An engine-driven hydraulic pump pumps hydraulic fluid to the blade drive motor, which drives the bandsaw blade on the blade unit responsive to operation of an internal combustion engine mounted on the saw carriage.

Abstract: To cut a workpiece along two different cutting directions, the band saw teeth are set horizontally by a band saw guide device and then the cutting head (CH) is moved frontward, for instance; thereafter, the band saw teeth are twisted downward by the same guide device and then the cutting head is moved downward. The machine is effectively usable in cutting off a test piece from a large workpiece. To improve the cutting precession, various novel devices are incorporated, such as a balance cylinder (B-CYL) for allowing the cutting head to move up and down smoothly; two back-and-forth cylinders (BF-CYL) for moving the cutting head back and forth in symmetrical pressure application; cutting head fix device (FD); a rigid guide column; band saw holding device (BSH); a slidable small-diameter driven wheel arranged within the cutting head (CH), etc.

Abstract: A band-saw-cutting system for cutting sections from a work in a substantially continuous, automated manner. The system includes a work carrier adapted to support one or more pieces of work and to be reciprocated to carry the work from a home position to a forward position in a cutting stroke to cut the work and back to the home position in a return stroke. The system includes blade-moving means for automatically moving the blade out of the cutting plane of the blade during each return stroke such that the work will not contact and rub against the blade during the return stroke, and for moving the blade back into the cutting plane prior to the initiation of the next cutting stroke. The system further includes means for automatically moving the work transversely against an adjustable fence to position the work relative to the cutting plane to cut desired thicknesses from the work during each cutting stroke. The fence includes means for insuring that the work is properly aligned with the cutting plane before a cutting stroke can be initiated. The system also includes a work-engaging means for holding the work during the cutting and return strokes and means for easily and quickly adjusting the tension on the cutting blade or to replace the blade. The invention permits a band-saw system to be utilized to cut work automatically with a high cutting rate and with minimal operator involvement.

Abstract: Strain mechanism for bandmill using deadweight lever mechanism in which undesirable effects of inertia of counterweight and friction at knife edges are reduced. Rolling diaphragm air cylinder is used in one of three positions. In first position cylinder extends between arbor carrier arm and plunger tube and supplies portion of saw strain permitting lighter counterweight. In second position it extends between counterweight arm and plunger tube and eliminates counterweights. In third position counterweight is supported on counterweight arm by yoke supported by cylinder which resiliently mounts weight.
