Abstract

Abstract Apparatus for handling and transferring bulb-shaped glass containers from one station in a container production line to another. A series of container handling vacuum chucks are linked together into an endless chain to pick glass containers in succession up from a first conveyor, to carry the containers through an inspection station, a coating tunnel and past a reject station and to then deposit the containers on a second conveyor. A control valve mounted on each chuck normally supplies the chuck with vacuum, however the control valve is actuated at the container discharge station, and may also be actuated at the reject station to supply air under pressure to the chuck to eject the container.
