Description

ABSTRACT:
An apparatus for feeding individual substrates from the top of a stack upon demand includes an air nozzle that directs air along the bottom surface of an airfoil located above the front end of the stack. The combined effect of air pressure from the nozzle and the shape of the airfoil serves to lift the leading edge of the top sheet in the stack above a restraining member. A paddle wheel drives the separated sheet away from the stack.
