A rotating cylinder is used to orient wood material, such as but not limited to blocks (e.g., finger joint blocks), preparatory to further processing. The rotating cylinder uses gravity and a tumbling action of the blocks to orient the blocks and move them through the cylinder. Unlike known apparatus such as vibrating conveyors, embodiments of the invention are relatively simple, vibration free, not prone to mechanical stress failures, are quiet, and use minimal horsepower to operate. Furthermore, embodiments of invention may advantageously reduce noise-caused fatigue amongst lumber workers, as well as reduce maintenance and power costs. The rotating cylinder may be part of a larger system for orienting wood material, such as blocks, for further lumber processing.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. An apparatus for orienting blocks, comprising: a cylinder having an infeed end and an outfeed end, the infeed end for receiving blocks having no particular orientation and the outfeed
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. An apparatus for orienting blocks, comprising: a cylinder having an infeed end and an outfeed end, the infeed end for receiving blocks having no particular orientation and the outfeed end for delivering the blocks in an oriented position, wherein the cylinder has a longitudinal axis positioned at an incline relative to a horizontal plane; and a rotation mechanism configured to rotate the cylinder about its longitudinal axis causing blocks received into the cylinder to be repositioned into the oriented position as the blocks progress through the cylinder toward the outfeed end, wherein the cylinder repositions the blocks into alignment with the longitudinal axis of the cylinder, wherein the cylinder further includes protrusions defined on an interior surface of the cylinder that are parallel to the longitudinal axis and adjacent to the infeed end, and wherein the protrusions have a rectangular cross section and are configured to lift the blocks only partway up a side of the interior surface of the cylinder as the cylinder rotates. 2. The apparatus of claim 1, wherein the rotation mechanism includes one or more rollers upon which the cylinder rotates. 3. The apparatus of claim 2, wherein the cylinder further includes one or more guides mounted on an exterior surface of the cylinder to position the cylinder on the one or more rollers. 4. The apparatus of claim 2, further comprising a motor configured to drive the one or more rollers and thereby cause the cylinder to rotate. 5. The apparatus of claim 4, wherein the motor transmits a rotative drive to the cylinder using a direct coupling to the one or more rollers. 6. The apparatus of claim 4, wherein the motor transmits a rotative drive to the cylinder using a belt and sheaves. 7. The apparatus of claim 4, wherein the motor transmits a rotative drive to the cylinder using a chain and sprockets. 8. The apparatus of claim 4, wherein the motor transmits a rotative drive to the cylinder using a gearbox and gears. 9. The apparatus of claim 1, further comprising a height-adjusting mechanism that adjusts the incline at which the longitudinal axis of the cylinder is positioned relative to the horizontal plane. 10. An apparatus for orienting wood material in a lumber processing system, comprising: a cylinder having an infeed end, an outfeed end, and a longitudinal axis positioned at an incline relative to a horizontal plane, the infeed end for receiving wood material having no particular orientation and the outfeed end for delivering the wood material in an oriented position, wherein the cylinder is configured to reposition the wood material into alignment with the longitudinal axis of the cylinder, the cylinder including protrusions defined on its interior surface that are parallel to the longitudinal axis and adjacent to the infeed end, and wherein the protrusions have a rectangular cross section and are configured to lift the wood material only partway up a side of the interior surface of the cylinder as the cylinder rotates; and means for rotating the cylinder about its longitudinal axis to reposition wood material received into the cylinder for lumber processing into alignment with the longitudinal axis of the cylinder as the material progresses through the cylinder toward the outfeed end. 11. The apparatus of claim 10, wherein the means for rotating the cylinder comprises one or more rollers that contact an exterior surface of the cylinder. 12. The apparatus of claim 11, wherein the cylinder further includes one or more guides mounted on the exterior surface of the cylinder to position the cylinder on the one or more rollers. 13. The apparatus of claim 10, wherein the means for rotating the cylinder comprises a motor in communication with the cylinder, wherein the motor imparts a rotative drive that results in rotation of the cylinder. 14. The apparatus of claim 13, wherein the means for rotating the cylinder further includes one or more rotation mechanisms that communicate the rotative drive of the motor to the cylinder. 15. A system for orienting blocks for further processing, comprising: a cylinder having an infeed end, an outfeed end, and a longitudinal axis positioned at an incline relative to a horizontal plane, the infeed end configured to receive blocks having no particular orientation and the outfeed end configured to deliver the blocks in an oriented position, wherein the cylinder is configured to reposition the blocks into alignment with the longitudinal axis of the cylinder, the cylinder including protrusions defined on its interior surface that are parallel to the longitudinal axis and adjacent to the infeed end, and wherein the protrusions have a rectangular cross section and are configured to lift the blocks only partway up a side of the interior surface of the cylinder as the cylinder rotates; a rotation mechanism configured to rotate the cylinder about its longitudinal axis causing blocks received into the cylinder to be repositioned into alignment with the longitudinal axis of the cylinder as the blocks progress through the cylinder toward the outfeed end; a chute in communication with the infeed end of the rotating cylinder for guiding blocks into the infeed end of the cylinder; and a transporting mechanism in communication with the outfeed end of the rotating cylinder for receiving the oriented blocks from the cylinder and transporting the oriented blocks for further processing. 16. The system of claim 15, wherein the transporting mechanism is a conveyor onto which oriented blocks are delivered from the rotating cylinder.
