Abstract: In ovens which are divided by baffles to form zones, and through which conveyor belts pass, seals are positioned to prevent the flow of gases between zones. The seals are positioned between the baffle and the belt, and comprise a plurality of brushes extending from the baffle across the width of the belt and positioned so that at all times at least one of the brushes is in contact relationship with a non-foraminous portion of the belt.
