A first bring up zone of a camel-back oven utilizes a plurality of short and/or medium wave infrared lamps to raise the component temperature up to a desired level. Once within the paint baking oven, the component enters into the bring up zone where a computer activates the requisite number of infrared lamps at the proper intensity to achieve the desired component temperature. While the infrared lamps are activated, inlet air is directed over the lamps to prevent them from overheating. The invention allows for smoother car finishes by preventing bubbling and pops and raises the component temperature more quickly than conventional dark radiation panels.

Paint baking oven having a bring-up zone utilizing short and medium wave

A paint baking oven utilizes air flow throughout the oven to ventilate solvents and/or resins which evaporate off during the paint baking process. Air is continuously introduced through air seals located along the paint baking oven at various points. This ventilation air is directed toward the center of the paint baking oven where it is exhausted at a rate proportional to the rate at which the ventilation air is introduced into the paint baking oven. Removing the solvent and/or resin laden air from the paint baking oven results in a more desirable final finish on the component being baked.

Method and apparatus for ventilating a paint baking oven

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.
