ABSTRACT:
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.
