ABSTRACT:
An apparatus for feeding individual substrates from the top of a stack of substrates includes a paddle wheel having a hub with a plurality of blades attached thereto. The paddle wheel is positioned in driving relation to the substrate stack. As the paddle wheel is rotated, the blades come in contact with a spiral track which retards the motion of the blade tips through controlled bending and thereby stores potential energy in the blades. Continued rotation of the paddle wheel allows the blades to spring forward from the track just prior to or during substrate contact thereby changing the potential energy of the blades into kinetic energy. The sudden acceleration of the blades due to the change from potential to kinetic energy causes an increase in inertial separation of the top substrate in the stack from the remainder of the stack.
