Apparatus for processing table and bed linen which embodies no-iron fabrics which may be composed in at least a substantial part of polyester fiber, or may be composed of other fibers which have been treated to provide no-iron characteristics (linen being used in a generic sense rather than to identify the fiber composition). The apparatus of the present invention embodies a pair of platens which are relatively movable to provide for the positioning of the stack of layers of textile fabric between the platens. Pressure means is provided to apply mechanical pressure to the stack of linens and each platen is hollow and has fluid connections for steam and vacuum. Each platen is perforated and a mask is provided to adjust the perforated area precisely to the area of the layers of fabric placed between the platens. Heater means may be provided to maintain each platen above the dew-point temperature of the steam supplied thereto.
Apparatus for smoothing bed and table linen and like material comprising a pair of platens, mounting means for said platens operable to displace said platens relative to one another between open and closed positions respectively, in the open position said platens operable to receive a stack of multiple layers of said material therebetween, pressure means operable in the closed position of said platens to bias said platens toward one another with a predetermined pressure to compress the stack of material disposed therebetween, said platens having fluid passageways in their confronting faces and connections for applying vacuum and supplying steam to said passageways, and valve means connecting said connections to sources of vacuum and steam, said valve means being operable to initially supply vacuum to one platen and supply steam to the other platen and then subsequently to supply steam to said one platen and to apply vacuum to said other platen.
