METHOD AND DEVICE FOR COOLING AND DRYING CLOTH TREATED WITH STEAM

PURPOSE:To prevent the generation of cooling creases by subjecting a wound cloth layer mounted in a closed oven to a steam treatment, gradually cooling the wound cloth layer by the actuation of a vacuum pump while controlling the amount of discharged steam through a steam-discharging pipe, and subsequently discharging the steam through a discharging pipe having a larger diameter than that of the above- mentioned pipe. CONSTITUTION:A wound layer-like cloth 4 is mounted in a closable steam oven 1 and subjected to a steam treatment. Valves 10, 11 and 14 are opened to release out the steam in the oven and when the pressure of the oven reaches the atmospheric pressure, the valve 14 is closed. The valve 12 is opened and simultaneously a vacuum pump 16 is actuated to subject both the outer layer portion and core portion of the cloth wound layer 4 to a vacuum treatment to discharge the steam through a piping A for discharging the steam while operating a manual valve 17 for the fine adjustment of the flow of the steam to adjust the discharging amount of the steam in the oven, thereby gradually drying the cloth 4. A valve 13 is subsequently opened to further discharge the steam in the oven through a steam-discharging piping B having a larger diameter than that of the above-mentioned piping A, thereby cooling and drying the cloth 4.
