ABSTRACT:
An oven for drying and curing a film of paint, ink, or the like on a continuous strip of metal has a non-rectangular, and preferably oval, elongated oven chamber without sharp internal corners. By avoiding sharp corners in the oven, air flow is more uniform and deposits of condensed fumes are minimized. In some embodiments no internal bracing structure required. The absence of internal structure is permitted by the oven's walls, oval shaped in transverse cross section, which result a naturally self supporting structure. Cleaning nozzles may be provided for washing the inside of the oven without need for people to enter the oven.
