Abstract

A web dryer structure for thermal removal of moisture from a traveling web such as a web of paper coming from the press section of a paper making machine including a row of upper dryer drums and a row of lower dryer drums with the drums positioned to carry the web in a sinuous path successively between the upper and lower drums and the web wrapping the upper and lower surfaces of the drums respectively with upper and lower looped felts wrapping the web on the upper and lower surfaces of the drums with the felt guided by guide rolls which are shifted laterally of the spaces between the drums a distance in the direction of web movement so that the pockets formed between the felts and the drums are pressurized due to the induced flow of air by the traveling felts and the guide rolls pumping air through the felts.
