Abstract: Exhaust apparatus for a continuous metal strip heat treating plant having means for influencing the continuous strip with air or heat-treatment medium, which is supplied to the continuous strip so as to flow essentially parallel along the strip, and an opening which permits the heat-treatment medium to pass outward from one surface of the continuous strip.

Abstract: An arrangement for a process plant which provides heat treatment of strip-shaped products, such as a paper web, the arrangement including a plurality of lamps operating with infra-red radiation. Channel means are provided for conducting a supply of air or some other heat treatment medium and directed against the strip undergoing the processing by means of a heat treatment ramp positioned adjacent the strip. The air or some other suitable heat treatment medium is directed and supplied to flow essentially parallel to the strip of the product. The apparatus for supplying the air directs the air parallel to the product being dried, in order to avoid blowing through the product.
