Abstract of the Disclosure The invention relates to a web guiding structure in a drying section downstream from a coating device and having suspension and infrared dryers and with a directly preceding coating device for paper or board. The structure is characterized by a rigid beam-like chest-like web bend device with blowing elements adapted to produce a pressurized gas cushion for the web for contact-free bending of the web in its direction through an angle between 50° and 120° so that with an increase in its distance from the bending device the web also moves away from the coating device, following the bend device a heating device or a suspension device having beam-like, chest-like blowing air guide devices in each case for producing a course of the web undulating in the direction of movement of the web (web valleys and crests extending in the transverse direction) on the upper and lower sides of the web and further dryers with radiation and/or a hot gas action and alternately arranged drying devices in the form of infrared dryers and suspension dryers alternating at least twice.
