Abstract: In a feeder supplying assembly components to another machine, an electronic control device monitors a horizontal buffer zone. Pulses of compressed gas are intermittently employed to lift components upon detecting the absence of a component in a portion of such buffer zone. The grooved chute member has a shape resembling the symbol for a square root after replacing the angles with curves. The stream of flowing components can be quite fast because components are directed to fall into the downsloping gathering portion of the grooved chute at an upper, middle, and lower portions. More rapid multi-stage alignment of components is expedited by a zone underneath a deflector and a transition zone, with an alignment passageway between such zones.
