In the case of common trough mangles (1) used for the smoothing and drying of wet laundry pieces (11) wherein the hollow rollers (2) provided with roller wrappings (3) are only partially surrounded by heated pressing troughs (4, 5), a considerable amount of energy is wasted due to the absorption of cooler room air. In order to eliminate the cause of this deficiency, the invention proposes to cover the free area of the hollow roller (2) with a hood (6), whose rims (9) are sealed against the roller wrapping (3). The exhaust (8) of the steam is removed directly from the hood (6). This way, inside the hood (6) clean saturated steam is obtained and superheated, when the absorption from the hood (6) takes place in counterflow with regard to the travel of the laundry pieces (11). This superheated saturated steam is especially suitable as operating means for washing machines or the like.

A method of mangling wet laundry which comprises the steps of: closely juxtaposing a heated trough-shaped surface with a portion of the periphery of a roller covered with a steam-permeable wrapping; rotating said roller to draw said wet laundry along said surface while pressing said wet laundry with said wrapping against said surface whereby steam is genrated by the contact of said surface with said wet laundry, said steam penetrating into the wrapping of said roller; sealingly enclosing at least most of the balance of the periphery of said roller in a hood and evacuating said hood to withdraw steam penetrating into said hood through said wrapping upon generation by contact of said wet laundry with said surface; and substantially completely excluding ambient air from penetrating into said hood while evacuating steam therefrom by maintaining the pressure in the hood at a pressure equal to or only slightly above ambient pressure whereby the steam evacuated from said hood is substantially free from air.
