Abstract: A card injecting apparatus in which an air gun directs a jet of air underneath a stack of articles for lifting the articles above a supporting surface to form a space between the lowermost article and supporting surface. Additional jets of air are directed by the air gun for injecting a card into the space. The air gun is formed of two portions, one portion defined by a stationary member and the other portion defined by a slider member which is movable relative to the stationary member between two positions for successively feeding cards from spaced apart hoppers to the air gun.
