Abstract
A three row drying cylinder group for a drying section of a paper machine or the like. The bottom cylinder row felt only passes through the bottom row. The top cylinder row felt passes from the top row, wraps the first middle row cylinder as a deflection element, passes over the next top row cylinder, and then is guided so that the opposite side of the top felt passes the next middle row cylinder and is guided back to the top row to alternate between the two ways of passing the middle row cylinders. Those middle row cylinders which are deflection elements may be heated or not and may deliver suction or vacuum to hold the web to the felt.
