Apparatus having an elevated trackway and a pick-up head arranged thereon for automatically plucking increments of fibers from one or more bales, delivering such increments of fiber to a position above a hopper feeder, and dropping such increments of fiber therein, all in a predetermined cycle and in response to a fiber demand signal from the hopper feeder. Such apparatus includes a suction conduit disposed above the hopper feeder and adjacent the path of travel of the fiber increments as they are dropped into the hopper feeder, with such suction conduit being connected to a continuous vacuum source. A valve is disposed in the suction conduit, and is opened when the pick-up head commences its cycle and closed when the pick-up head completes its cycle.
