Abstract:
1. A method for conveying and singulating logs, the method comprising: receiving logs along a conveying path defined by stationary log-bearing surfaces of a log singulator; and rotating a plurality of shafts of the log singulator at least 360 degrees and thereby rotating a plurality of lift arms extending from each shaft such that the lift arms of one of the shafts engage one of the logs on a lower location of the log-bearing surfaces and lift the log over a top point to a higher location on the log-bearing surfaces at which the log is engaged by the lift arms of a next one of the shafts along the conveying path, the log thus being lifted over the top points and conveyed along the conveying path, wherein at least one of the top points is defined by one or more surfaces that define a generally smooth contour over which the logs can be moved.
