Abstract
A dryer for a web of textile material having at least one dryer compartment, in which at least one air-permeable cylinder is rotatably disposed, around which the web of material may partially loop so that heated drying air may flow through the web of material. At least one fan is provided by which humid drying air from the inside the at least one cylinder may be suctioned off from a front-sided opening of the at least one cylinder and discharged as discharge air through a duct. The dryer includes at least one sensor for determining the humidity of the discharge air flow, the data thereof being processed in a control with the initial humidity of the web of material and the humidity of the fresh air flow for closed loop control of the evaporative capacity of the dryer.
