Abstract: A feeding device is disclosed for orienting and transporting round symmetrical parts, such as caps or closures. The device has a receiving bin to receive a plurality of unoriented parts and a rotary disc located in a bottom portion of the receiving bin to successively agitate and transport the symmetrical parts. The disc is driven by an endless belt which also engages a drive pulley. The symmetrical parts are transported from the rotary disc by the endless belt and are caused to engage a balance rail located along their travel path. Properly oriented parts will continue to be transported on the endless belt, while those which are improperly oriented will fall off the endless belt and return to the receiving bin.
