Abstract: An ending apparatus for a log ladder (2), wherein the log ladder (2) sorts, feeds and sequentially indexes logs (54) along a longitudinal array of laterally extending adjacent log cradles (4, 8, 12), having, in the log cradles (4, 8, 12), exclusive of a downstream—most log cradle (12) in the longitudinal array, log translating means (64) for laterally translating the logs (54), when the logs (54) are in the log cradles (4, 8) exclusive of the downstream—most log cradle (12), so as to abut one end of the logs (54) against an edge (72) of the log ladder (2), wherein the log translating means (64) has selectively actuable rollers (64) mounted within a lower vertice of the log cradles (4, 8), wherein the selectively actuable rollers (64) are mounted in lateral array and the rollers (64) are generally hourglass-shaped so that in longitudinal cross section the rollers (64) have a longitudinal profile generally matching the longitudinal profile of a longitudinal cross section of the log cradles (4, 8), and wherein the log translating means (6, 10) further has first sensing means cooperating with the selectively actuable rollers (64) for sensing the presence of the logs (54) in the log cradles (4, 8) and triggering selective rotation of the selectively actuable rollers (64) whereby said logs (54) are ended against the edge (72) of the log ladders (2), and wherein the log ladder further has second sensing means (62), cooperating with lifting and culling means (6, 10, 14) corresponding to the log cradles (4, 8, 12), for delayed triggering of the lifting and culling means when the logs (54) are held in the log cradles so as to increase dwell time of the logs on the log translating means (64).

Abstract: A log ladder for sorting, feeding and indexing in a downstream direction a stack of logs into a stream of logs has a first notched step and a first set of collectively actuable lift arms pivotable about a first axis, and a second set of collectively actuable lift arms downstream of the first set of lift arms, actuable independently of the first set of collectively actuable lift arms and pivotable about a second axis, the first set of lift arms actuable from a lowered position to a raised position whereby the first set of lift arms are engageable with a log at a first engagement point thereby to raise the log from the stack of logs, the first axis downstream of the first engagement point relative to the direction of movement of said logs in said stream of logs, the first axis generally below the first notched step, the first notched step adapted to receive and hold the stack of logs, the first set of lift arms in the raised position positioning the log so as to deposit the log into a second notched step below the first set of lift arms in the raised position and downstream of the first notched step, the second set of lift arms actuable from a lowered position to a raised position whereby the second set of lift arms are engageable with the log in the second notched step at a second engagement point thereby to raise the log from the second notched step, the second axis downstream of the second engagement point and generally below the second notched step, the second set of lift arms in the raised position positioning the log so as to deposit the log from the log ladder.
