Abstract
Apparatus for pushing a loaded open-ended carrier sleeve and folding the trailing dust flaps of the sleeve. Flight bars attached to endless chains located below the path of travel of the carrier sleeve initially move the sleeve. Pusher bars or lugs attached to endless chains located above the path of travel of the carrier sleeve engage the trailing panel of the sleeve and accelerate the sleeve away from the flight bars. Fingers attached to the pusher bars contact the trailing dust flaps prior to the pusher bars contacting the trailing panel of the sleeve and fold the trailing dust flaps before the sleeve is accelerated along its path of travel.
