Abstract
The flow of paint in a liquid paint stripe covering the inside of a side-seam weld extending along the top of a horizontally-disposed food can is controlled by applying induction heating to areas of the can on each side of the stripe, whereby a temperature gradient directed upwardly through the can is established to limit downward gravity flow of the paint before it sets, and thereby prevent formation of ridges and bubbles at the edges of the stripe.
