The process includes guiding the material web through the at least one impingement dryer, and monitoring the material web for web breaks in at least one of a region, viewed in a web travel direction, before an intake into the at least one impingement dryer, after an exit from the at least one impingement dryer and within the at least one impingement dryer. The process further includes at least partially deactivating the at least one impingement dryer when a web break is detected.
