A device for mounting and dismounting a band-saw blade has a movable support frame and a plurality of retaining elements distributed on said support frame and configured to temporarily adhere to the outer flat side of the band-saw blade at various locations along the contour of the band-saw blade, thereby exerting an outwardly directed force on the outer flat side of the band-saw blade.

A method for constructing a lower section of a sawmill carriage assembly comprises holding structural components between a pair of metal plates, and affixing the plates and the structural components together. The structural components may include wheels that guide the sawhead in linear movement along a track on a sawmill bed, to which the carriage base is attached. The structural components may also include a track cleaning system disposed between the metal plates. The track cleaning system maintains optimal track conditions.

A band saw machine is adapted for cutting a lumber, and. includes frame body unit, a transport unit, a hold-down unit, a cutting unit and a drive unit. The transport unit includes an endless conveyor belt extending in a front-rear direction through the frame body unit for transporting the lumber. The hold-down unit includes an endless hold-down belt extending in the front-rear direction through the frame body unit. The endless conveyor belt and the endless hold-down belt are driven by the drive unit to rotate synchronously to carry the lumber to be cut by the cutting unit.

A band saw machine is adapted for cutting a lumber, and includes a frame body unit, a transport unit, a cutting unit, a cleaning unit and a guide unit. The frame body unit includes a base plate and a hood body extending rearward from the base plate and cooperating with a conveyor belt of the transport unit to define an output passage. The cutting unit is adapted to cut the lumber into an upper piece and a lower piece. The guide unit includes two guide rollers mounted to the hood body, extending into the outlet passage, and adapted to separate the upper piece from the lower piece. The cleaning unit includes an air lance for directing an air stream to the conveyor belt.

A cutting fluid delivery controller for a sawmill, and methods and systems for controlling delivery of cutting fluid to a saw blade in a sawmill. The saw blade is driven by a motor. The speed of the motor is regulated by a throttle lever having an idle speed position and a cutting speed position. The cutting fluid delivery controller includes a fluid valve configured to automatically turn on a flow of cutting fluid to the saw blade when the throttle lever is set to the cutting speed position, and to automatically turn off the flow of the cutting fluid when the throttle lever is set to the idle speed position. The cutting fluid delivery controller interconnects the fluid valve and the throttle lever to allow the operator to simultaneously control operation of the saw blade, and the flow of the cutting fluid to the saw blade, with a single operator manipulable actuator.
