Abstract
Methods and apparatus for coating the interior side seam of can bodies. The can bodies proceed down a line in serial order with end toward end and uniformly spaced from each other down the line extending from a can body side seaming machine. An airless spray coating is shot into each can body from the front and the rear to leave a coating of plastic along the interior side seam of a soldered can body.

An apparatus for spraying the inside of the can bodies having side seams and which can bodies pass end to end down a can body line from a can body side seamer with each can body spaced a distance from each other can body, said apparatus comprising in combination with said can body line;
- a detector positioned alongside said can body line for sensing the presence of a can body as it passes, spray means fixedly positioned alongside said can body line out of the path of can bodies passing therealong and directed towards said can body line downstream thereof for successively spraying side stripe material through the space between can bodies into an open end of each can body moving along said can body line and unto the interior of moving can bodies, and
- control means connected to said detector and to said spray means for causing said spray means to intermittently spray side striping material beginning at a time each can body has passed said spray means and for a period of time after each can body has passed said spray means but during such time as the interior of the respective can body is in the path of spray from said spray means.
