Abstract: A bandsaw makes simultaneous, spaced-apart cuts in hard or soft materials with a single bandsaw blade. The invention is ideally suited to cutting spaced-apart parallel surfaces to form support blocks, however, different embodiment may be controlled or programmed to make parallel or non-parallel cuts at varying angles. The single bandsaw blade rides on circular wheels on both sides of a gap or passageway, such that a first portion of the blade crosses the passage along a first, upper path, and a second portion of the bandsaw blade crosses the passage along a second, lower path. A table moves the material through the passage, whereupon the material is simultaneously cut along two planes corresponding to the upper and lower paths of the bandsaw blade. A preferred embodiment includes a first set of upper and lower wheels on one side of the passage, and a second set of upper and lower wheels on an opposing side of the passage.

Abstract: A tensioning mechanism for a band saw includes a tension spring assembly coupled with a sliding tension bracket which is adjustably coupled with an upper arm of the band saw. The sliding tension bracket engages an upper band wheel which couples with a band saw blade. A cam assembly is coupled with the tension spring assembly, the cam assembly imparts a rotational force which is translated into a linear tensioning force by the tension spring assembly upon the band saw blade. A cover assembly is selectively engaged with the cam assembly through use of a biasing assembly. The cover assembly includes an index indicator for identifying an index position and includes a handle which enables a user to selectively engage and rotate the cover assembly. The rotation of the handle in turn rotates the cam assembly applying the rotational force which is translated into the tensioning force.

Abstract: A band saw quickly changing device for a band saw machine is pivotally connected to a turning wheel of the machine body, including a sliding base, two limiting bases, a spring, a support plate, a micro-adjusting rod, a quickly adjusting device and a bottom base. The quickly adjusting device is composed of a shifting block, an eccentric block and a handling rod. The eccentric block has an eccentric shaft hole for pivotally connected on the shifting block, and the handling rod has a pivotal member formed in its upper end to fit in the eccentric shaft hole and fixed therein with a bolt. When the handling rod is swung backward, the sliding base is moved down to let the upper turning wheel move down, loosening the band saw extending around the two turning wheels of the machine.

Abstract: 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.
