This relates to a feeder for feeding articles on a continuous basis one behind the other. The feeder includes a plurality of flight bars which are mounted for rotation about an axis with the flight bars being circumferentially spaced and having article engaging elements carried thereby. The flight bars are so mounted wherein the distances of the flight bars from the axis of rotation may be infinitely varied to thereby infinitely vary the circumferential spacing between adjacent flight bars. In this manner, the feeder may be readily adjusted so as to feed articles of all dimensions within a prescribed range.
