ABSTRACT:
A feeder has an endless belt conveyer which removes flat articles one-by-one from the bottom of a stack and transports them downstream to a delivery point. A chamber is connected to a vacuum source in timed sequence to apply a vacuum through apertures in the belt to pull the underside face of the lowermost article against the upper surface of the moving belt. Further, restraining chambers are connected to a vacuum source to engage the article next thereabove and prevent its premature downstream travel.
