Abstract
A convection air holding zone utilizes turbulent ejector air flow along paths parallel to the path of travel of the article being baked in a paint bake oven. Air recirculation means are provided within the convection air holding zone which filters dirt particles from the air and a heat source is applied to the air to compensate for temperature loss due to heat exchange with the article and oven walls. Maintaining a turbulent air flow over the articles being baked in the convection air holding zone helps insure an even temperature throughout the zone, thereby enabling a more consistent paint finish on the article.
