    Abstract: A method of sawing wood to produce a smooth rotary planed surface wherein a piece of wood is moved into a rotary saw in the direction of cutting while maintaining the sawed pieces in spaced relation and out of substantial contact with the back edge of the saw by shifting a splitter transversely in response to lateral transverse deflections of the saw. A rotary saw machine having a pair of saw guides disposed on opposite sides of a saw blade mounted for axial movement upon a saw arbor, each saw guide comprising a wear member that is flexibly and resiliently supported for movement in a direction substantially parallel to the axis of blade rotation, each wear member having a surface that is maintained in contact with the side surface of the saw blade under a resilient preload force that urges the saw blade against the other wear member to rigidify the saw blade and maintain the blade in a predetermined cutting plane. A rotary saw machine having a pair of saw guides disposed on opposite sides of the saw blade mounted for axial movement upon a saw arbor, means for yieldably supporting the saw guides for movement in a direction substantially parallel to the axis of blade rotation, and a splitter disposed adjacent the back edge of the saw blade and mounted to said support means, said splitter being free to move laterally in a direction substantially parallel to the axis of blade rotation in response to transverse deflections of the saw blade.

    Abstract: A band saw of the commercial type employed in lumber mills having a pair of spaced apart first and second wheels and a continuous saw blade or band entrained around said wheels, an improved saw guide and apparatus comprising one or more springs yieldably urging the first wheel in a direction generally away from the second wheel to apply tension to the saw blade; and a rapid response-low inertia saw guide that will eliminate or substantially reduce momentary slack in the saw band while maintaining the cutting edge of the blade in a predetermined cutting plane. In a band saw of the kind described, the saw guide being more particularly characterized in that it is disposed intermediate the first and second wheels and comprises a contact member positioned to engage the inside surface of the blade as the blade moves from the first wheel toward the second wheel, the contact member having a first contact portion that provides a fixed line of contacts forward of an imaginary line connecting the points of tangency between the wheels and a movable contact portion that contacts the blade in a region intermediate the first contact portion and the first wheel; and a rapid response-low inertia means urging the movable contact portion against the saw blade to maintain tension in that area of the blade between the first wheel and the fixed line of contacts.

    Abstract: Method and apparatus for operating a rotary saw with saw guides that apply lateral surface pressure to guided saw blades mounted on a saw arbor and more particularly wherein each of a plurality of saw guides is positioned in spaced relation as to engage the sides of a saw blade with little or no pressure until after the saws have developed substantial inertia and speed of rotation, the saw guides then being moved into pressure engagement with the saw blades while simultaneously positioned to establish predetermined guide planes for each of the saw blades. A saw guide for rotary saw machines having at least one rotary saw blade keyed to a saw arbor and axially movable thereon, the saw guide comprising a pair of substantially parallel support arms having contact surfaces for engaging opposite sides of a rotary saw blade, means for securing the support arms together in back of the trailing edge of the saw blade, and means for selectively positioning the support arms in predetermined spaced relation in front of the leading edge of the saw blade to establish a pressure contact with the guided saw blade or allow the support arms to move apart and release the pressure on the saw blade.

    Abstract: In combination with a saw machine having a relatively thin circular saw mounted upon an arbor with floating axial looseness and a saw guide defining a limiting control plane for guiding the leading edge of said saw, a splitter mounted for lateral movement and laterally positioned by the rear edge of said saw. A splitter for use in saw machines having a circular saw and comprising a pair of spaced contacts, each contact having a bearing surface for making contact with opposite sides of a circular saw, and a divider member having a plurality of resilient contacts that extend into a region above said spaced contacts and in trailing relation to the rear edge of a saw.

    Abstract: A self-guiding circular saw blade for use in making a following cut, said blade being formed with a plurality of noncutting appendages that project laterally from the saw blade in the region of its gullet line, each appendage being resilient and projecting laterally a distance substantially equal to but preferably greater than the kerf line of said blade. In a saw machine for cutting lumber, a pair of circular saw blades mounted on opposite sides of a cutting plane, one blade having a cutting depth overlapped relative to the cutting depth of the other for making a following cut in the precut of the other, said one blade being formed with a plurality of guiding appendages that project laterally from the saw blade in the region of its gullet line, each appendage being resilient and projecting laterally a distance substantially equal to but preferably greater than the kerf line of said one blade.
