Abstract
A sawmill and method for sawing a log. The sawmill includes a transfer conveyor to convey a log quarter wedge segment to a log transport rig configured to orient the log quarter wedge segment so that an apex of the log quarter wedge segment is oriented in a downward direction. The log transport rig moves the log quarter wedge segment through a band saw configured to saw the log quarter wedge segment into two log eighth wedge segments. A transfer conveyor is provided to gather the two log eighth wedge segments from the log transport rig and feed the two log eighth wedge segments sequentially to a resawing rig comprising a conveying device and from two to six band saws configured to saw boards from the each of two log eighth wedge segments in succession as each of the two log eighth wedge segments are transported through the resawing rig.
Claims20
A sawmill comprising:
- a band saw configured to saw a log quarter wedge segment into two log eighth wedge segments;
- a supply conveyor configured to supply the log quarter wedge segment to a log transport rig configured to orient the log quarter wedge segment so that an apex of the log quarter wedge segment is oriented in a downward direction, wherein the log transport rig is configured to move the log quarter wedge segment through the band saw, wherein the two log eighth wedge segments have at least one flat face;
- a resawing rig comprising a conveying device and from two to six band saws oriented parallel to a flat face of each of the two log eighth wedge segments prior to cutting each of the two log eighth wedge segments;
- wherein the resawing rig comprises rollers attached to the resawing rig at an angle of 45 degrees, wherein the rollers are configured to contact only one flat face of each of the two log eighth wedge segments as each of the two log eighth wedge segments are transported through the resawing rig;
- and
- a transfer conveyor configured to gather the two log eighth wedge segments from the log transport rig and feed the two log eighth wedge segments sequentially to the resawing rig configured to saw boards from the each of two log eighth wedge segments in succession as each of the two log eighth wedge segments are transported through the resawing rig on the conveying device.
A method for sawing a log comprising,
- feeding a log quarter wedge segment from a supply conveyor to a log transport rig;
- orienting the log quarter wedge segment in the log transport rig so that an apex of the log quarter wedge segment is in a downward direction;
- transporting the log quarter wedge segment through a band saw;
- sawing the log quarter wedge segment into two log eighth wedge segments;
- transporting the two log eighth wedge segments on a conveying device in succession through a resawing rig containing two to six band saws, wherein the two to six band saws are oriented parallel to a flat face of each of the two log eighth wedge segments prior to cutting each of the two eighth wedge segments;
- wherein the resawing rig comprises rollers attached to the resawing rig at an angle of 45 degrees, further comprising contacting only one flat face of each of the two log eighth wedge segments with the rollers as each of the two log eighth wedge segments are transported through the resawing rig;
- and
- sawing two or more boards parallel to one flat face of each of the two log eighth wedge segments as each of the two log eighth wedge segments are transported on the conveying device through the resawing rig.
