Abstract

An air impingement system for heating and drying a web travelling around a roll of a drying section of a paper machine. The system comprises a single hood so positioned to surround only a first lower portion of the roll upon which the web travels and contacts the roll, leaving unwrapped a second lower portion on each incoming side of the roll where the web still contacts the roll. A fan, a heating device, and means for directing air blown by the fan onto the first lower portion of the web are provided. The hood is so positioned to allow air blown onto the web to return to the hood for confining the circulation air within the hood. The impinged air is applied mainly on the trailing side of the roll where the web contacts the roll, and preponderantly on the lower half of the roll allowing the use of small spaces available between drying cylinders for installing /modernizing machines using the basement floor.
