ABSTRACT:
An oven, having a series of separate and isolated chambers which are horizontally aligned and sealed from each other and the ambient atmosphere and through which a continuous element is passed for treatment by heated gas within the chambers, is disclosed. The oven is provided with means for circulating heated gas to the chamber of the oven last-to-be-encountered by the element and cascading such heated gas successively through the other chambers to the first chamber to be encountered by the traveling element, or in an upstream direction relative to the travel of the element. Thus, the source of heated gas for a particular chamber is from the next succeeding downstream chamber which is contrary to present day ovens wherein each chamber is normally supplied with its own burner system for separately temperature conditioning gas circulated to that particular chamber.
