Abstract
A paper machine comprising a single tier drying section including at least two dryer groups is disclosed. In one group, the axes of rotation of at least two consecutive drying cylinders lie substantially in a plane, and the axes of rotation of the vacuum rolls are disposed below the plane of dryer cylinders. In the next group, the axes of rotation of at least two consecutive drying cylinders lie substantially in a further plane which is non-coplanar with the plane defined by the dryers of the first dryer group. The vacuum rolls of the second dryer group have their axes of rotation disposed above the further plane. The dryer transfer which transfers the web from one dryer group to the next one includes a joint run of the felts of the respective dryer sections and a vacuum roll at the downstream end of the joint run. The joint run receives the web between the felts when the web passes through the joint run. The vacuum roll is disposed at the downstream end of the joint run for positively maintaining the web in close conformity with the receiving felt when the felts diverge downstream from the joint run. The felts are free from restraining devices as they pass through the joint run. A method for drying a web employing the disclosed apparatus is also disclosed.
