ARRANGEMENT FOR THE TRANSFER OF A TRAVELING WEB An arrangement for transferring a paper web from the last drying cylinder of a first single tier dryer group to the first dryer cylinder of a second single tier dryer group. The last of the first drying cylinders lies outside the first endless loop porous support belt of the first dryer group. The first or initial one of the second drying cylinders lies outside the second endless loop porous support belt of the second dryer group. A first guide roll lies inside the loop of the first belt and is spaced from the first cylinder. A second guide roll lies inside the loop of the second belt, is spaced from the second drying cylinder and is also spaced along the path of the first belt between the first drying cylinder and the first guide roll so that the second belt wraps around the second guide. roll and the web on the first belt contacts the second belt on the path of the first belt to the first guide roll. An air guide box upstream of the first guide roll and on the side of the first belt that is inside the first loop directs air against the first belt into the wedge shaped zone that is upstream in the path of the first belt toward the first guide roll for helping to transfer the web from the first belt to the second belt. The air guide box may have a stripper at the first drying cylinder to strip air off the first belt, may have a wall that diverges from the first belt in the path toward the first guide roll, and may have a deflection surface at the web for deflecting air passing along the first belt against the web and at the first guide roll.
