Abstract
A method for operating a steam trough mangle wherein exhaust air is separated into recirculating air and discharge air with the recirculating air remaining in the air circulation system of the mangle while the discharge air is subjected to a heat transfer process. The recirculating air and fresh air heated by the discharge air are both fed to a trough area of the mangle. The mangle or hot bed ironer in which this method may be carried out includes an air discharging apparatus inside a mangle area that is almost completely enclosed which is connected with a suctioning apparatus for exhausting air and also with the first flow chamber of associated heat transfer means. The heat transfer means has a second flow chamber connected to the suctioning apparatus.
