<p>A dryer apparatus for drying alternate sides of a web of paper comprises first and second single tier dryer sections. The first single tier dryer section includes drying cylinders for drying one side of the web, and the second section includes drying cylinders for drying an opposite side of the web. Means for transferring the web from said first single tier to said second single tier dryer sections are adapted to transfer a web in an open draw defined between first and second gaps. Said first gap is a divergent gap which is defined between the surface of a last drying cylinder of said first single tier of drying cylinders and a first felt and said second gap is a convergent gap which is defined between the surface of a first drying cylinder of said second single tier of drying cylinders and a second felt. The divergent gap is located opposite to the convergent gap. <IMAGE></p> |
