Förfarande för torkning av en materialbana och anordning för genomförande av detta förfarande

摘要

Process and device for drying a material web which together with a backing belt alternately runs across heatable drying cylinders which are contacted by the material web and across guide rolls contacted by the backing belt. At the travel section of the material web from one drying cylinder to the next, drying air is fed to the material web in relatively narrow blow zones. Located between the narrow blow zones are relatively wide steam release spaces from which the water vapor-laden drying air is removed.
