ABSTRACT:
An apparatus for drying a travelling wet fibrous web is provided which comprises a rotating air-permeable drum. The drum is at least partially surrounded by a hood which has an interior space for receiving a flow of air and directing the flow of air through a permeable inner wall towards the outer surface of the drum. At least a portion of the hood is divided into individual sections in a cross-machine direction. Apparatus is provided for supplying a flow of drying air at a first temperature to the hood, and for supplying profiling air at a selected different temperature different from the first temperature to at least one of the individual sections.
