Abstract
This disclosure relates to a capping machine for applying caps to containers, such as jars. The capping machine is provided with a simple automatic cap feed wherein the caps are gravity fed through an orienting chute which directs the caps towards a cap locating station with which there is aligned a capping chuck. The caps are primarily advanced by gravity and as they approach the cap locating station, fluid jets, preferably steam, are directed against the caps to advance them to their positions in alignment with the capping chuck. Means are also provided for directing jets of steam into the top of a container to which a cap is to be applied to displace air between the container neck and the cap and thus create a partial vacuum within the sealed container.
