ABSTRACT:
A vacuum friction feeder including at least one vacuum friction belt provided with a plurality of holes, a pair of rollers, a table top provided with at least one suction port, an exposure table having a substantially horizontal top surface and a separator. The at least one vacuum friction belt is adapted to rotate around the table top while supported by the rollers such that a suction pressure can be drawn through the plurality of holes provided in the at least one vacuum friction belt as the plurality of holes pass over the suction port. The exposure table is operatively associated with the table top and is adapted to be movable relative to the table top in a plane defined by the substantially horizontal top surface to adjust the portion of the bottommost product in the stack of products exposed to the at least one vacuum friction belt.
