The applicator receiving the metal lids from an infeed conveyor and discharging the metal lids with sealant thereon to a discharge conveyor. The applicator includes a motor driven starwheel. The starwheel is mounted on top of a tabletop and driven in one direction. The starwheel has a plurality of cam followers spaced apart and extending outwardly from its circumference. The cam followers include cam follower bearings adapted for receiving a portion of individual metal lids thereagainst. A plurality of sealant guns are mounted on the starwheel. The sealant guns are under computer control and are disposed next to said cam followers. The sealant guns apply the sealant inside the metal lids. A motor driven magnetic wheel is mounted on top of the tabletop and disposed under the starwheel. The magnetic wheel is driven in an opposite direction from the starwheel.
