SUCTION ROLL WITHOUT SUCTION BOX, PARTICULARLY FOR A DRYER GROUP OF A PAPER MAKING MACHINE ABSTRACT OF THE DISCLOSURE The suction roll of a dryer group is in the path of the web and of the web support belt from an upstream dryer cylinder to a downstream dryer cylinder. The suction roll has an annular roll shell having a plurality of radial holes and being free of stationary inserts at least over the predominant part of the length of the roll shell. A hollow roll journal at at least one end of the suction roll connects vacuum into the suction roll and to the radial holes. In at least some of the holes there are respective deflector pieces. Each extends a short radial distance into the inside of the roll shell over a short radial portion. The deflector piece has a continuous channel which extends radially inward through the hole toward the inside of the roll in a direction substantially parallel to the direction of extension of the hole and the radially inward portion of the channel is curved in the direction contrary to the direction of rotation of the roll shell.
