description An apparatus for feeding individual substrates from the top of a stack of substrates upon demand includes a paddle wheel having paddles that are semi-cylindrical. The paddles buckle upon contact with the substrates rather than bending and thereby providing reduced normal force sensitivity to paddle deflection and reduced pressure since the force of buckling is a function of thepaddle cross-section rather than paddle length for all areas of the paddles except near the paddle wheel hub. The semi-circular blades reduce misfeeding and multifeeding while having an extended wear life.
