SHORT DEPTH CARTON FEED DRIVE

摘要

An improved carton feed drive includes feed dog drives for delivering carton blanks to transport lugs of a carton. Components of the feed dog drives are inclined to the vertical, providing ability to handle very short depth cartons by operating feed dogs in an operative run closely adjacent the transport lugs while the feed dog drives are inclined away from the transport lug drives so the respective drives to not interfere in any way to unduly limit the ability to handle short depth cartons. Feed dogs are selectively pivoted on their drives to positions for operative engagement of cartons, and are releasable to retracted positions to avoid carton damage as the dogs move to a return run.
