An apparatus ( 10 ) for feeding sliders ( 31 ) from a source of sliders to the slider insertion area ( 27 ) of at least two slider insertion devices ( 18, 19 ). A sensor ( 30, 52 ) on a sender track ( 20, 21 ) detects a lack of sliders ( 31 ) in the sender track. A signal is sent from the sensor ( 30, 52 ) to actuate a vibratory bowl ( 14 ) of sliders ( 31 ) and a plunger ( 35 ) to open a passage, thereby releasing the sliders ( 31 ) to a sender track ( 20, 21 ). When a sensor ( 46, 56 ) detects a lack of sliders ( 31 ) in a loading rack ( 25, 26 ) or a slider insertion area ( 27 ), the sensor ( 46, 56 ) signals a plunger ( 44, 58 ) and a pneumatic valve ( 48, 60 ) to open a passage to provide an air blast, thereby launching the sliders ( 31 ) onto the slider insertion area ( 27 ) of each slider insertion device ( 18, 19 ). A directional gate ( 33 ) sends the sliders ( 31 ) to either sender track ( 20, 21 ) prior to launching to either slider insertion device ( 18, 19 ), or a directional gate ( 79 ) sends the sliders ( 31 ) to either slider insertion device ( 18, 19 ) after launching of the sliders ( 31 ).
