A web-drying apparatus having a hood enclosing two parallel transverse rows of drying cylinders set one above the other at a considerable distance from each other, each web run between the upper and lower rows of drying cylinders being lined on either side with a vertical row of jet boxes each of which has a convex profile along the side facing the web and which alternate in position with the jet boxes in the opposite row, so that the web will be dried on the drying cylinders and also as it runs in a wavy path from one row of drying cylinders to the next, while the web is exposed to a hot blast from the convex side of each jet box on both sides of the web, but without touching the jet boxes.
