ABSTRACT:
An apparatus which uses vacuum to singly feed pieces from a stack. The feeding apparatus has a plate supporting a bottom of the stack and defining a plurality of plate apertures. The plate is connected to a drive mechanism which moves the plate between rearward and forward positions. The plate apertures are in fluid communication with a first vacuum source which provides a vacuum to the plate apertures. When the drive mechanism moves the plate from the rearward to the forward position, the vacuum source provides a vacuum to the plate apertures for holding a bottom-most piece of the stack against the plate. As the bottom-most piece of the stack is moved forward, a metering member prevents other pieces of the stack from being moved along with the bottom-most piece.
