ABSTRACT:
In a drying section of a paper making machine, the paper web is conducted through a plurality of single tier dryer sections and then transferred to at least one final double tier dryer section for completing the drying process. The paper web is threaded through the open draw between the single tier dryer sections and the double tier dryer section and through the open draws between the lower cylinders and the upper cylinders in the double tier dryer section by use of air jets which blow at the paper web from opposite sides thereof. The air jets include at least one jet which blows in a direction generally opposite to that of the paper web.
