To all whom it may concern.'

V Be it known tha-t I, 'Si-DV10 ASoi-rmvozr-K, a subject of *the German Emperor, residingat San Remo, Italy',^have invented 'certain new and alseful Improvements in Drying Plants for iTextileFabrics, of whichA the following is I'a specification. 'f

'The object of Kthe presentinvention relates toimprovements in drying apparatus heated bysteam or any other suitable medium and which are mainly used for the drying of textile fabrics .and :other woven fabrics.

The object of invention aimed at is to increase the heating surface ofthe "heating plates in such drying apparatusas vwell as to increase their eifectby providing an aircirculation on their surface.

The novelty `of the invention :consists mainly in providing the plates with perfof rations, so that the inner walls of 'the 'same will bear forth heat also and furthermore allow of a more complete circulation of the air in the drying apparatus around the heating plates, through the same, `and the textile fabric. y

In the drawings the object of the invention is illustrated in several constructional forms as well as in its various applications for the drying of woven fabrics.

Figures l, 3 and 5 are top views of the plate in three different forms;` Figs. 2, 4 and 6 are each a cross section of the plate as per Figs. 1, 3 and 5; Figs. 7, 8, 9`and 10 show the use of the plate for drying purposes in frames, hot flues, etc., wherein, Fig. 7 illustrates such a drying device in side View with the shell removed, andthe plates, one of which is shown in section, are mounted horizontally; Fig. 8 shows the same drying device in transverse section with the shell removed; Fig. 9 also represents a side view of the drying device with removed shell, in which the plates are arranged vertically and Fig. 10 shows a transverse section of the last mentioned arrangement with removed shell.

The new drier is constructed of two steel plates which form a hollow chamber. In the interior of the chamber baffle plates form, in the usual manner, the channels for the steam circulation. The two side plates a are fastened to each other by means of the edgebars and the baffle plates c by meansk of rivets or the like. The edge or curb-bars b are provided at suitable places with steam inlet and outlet nozzles d.

apertures in v1the side plates alarey cut out in alinement with each other (Figs. Al and?) and side waflls are providedl'for the air Apasnicating with said apertures. These Lpipe sections f fare highly heated 'by Ythe steam circulation around them and betwe'en the 'filo' form vthe air 'passages in the drier,

plates. In Figs. 3, 4, 5 and y6 the perforations lare formedinfthe following manner: The jplates a are, where `the fpenforations are to 'be struck yup inwardly such .a manner that two corresponding flanges extending inwardly lfrom :thesurfa-ceplates a overlap,

andarefastened together by electric welding .or -other .suitable insane.. flhe-ib ale 'riolatesl .c vwhich form the steam channels in the described-plates can be arranged in a straight form between the rows of perforations (Figs. l and 3) or can be curved (Fig. 5).`

The perforations can have any desired form.

The new drier plates serve principally, as before mentioned, for drying textile-fabric bands, of woven goods and the like and t-he mode of working of same is explained by Figs. 7 to l0.` The shown drying plant consists in this instance of machine frames the adjustable warp-supports 71. adjusted by the right and left hand threaded screws i which are mounted in the frame g, the shell 76 which incloses the drying device, and the reels Z over 'which the textile fabric bands are conducted. In place of the old heretofore used` solid drier plates between the bands, the new drier plates a' described above, are now used. The same reach from one side of the shell k to the other and divide the drying apparatus in as many compartments vas plates are used. Through a y.

nozzle m in the bottom ofthe drying apparatus an air current is applied by pressure and taken olf at the nozzle a in the top of the apparatus.

yIn usingthe new plate a with its perforations f the .air current, which passes through the perforations f, is supplied with fresh heat and it is given the possibility to penetrate the web of textile fabric in a more or less vertical direction without any harm to the same. The air current is distributed by means of the perforated plates evenly in the whole compartment in such a manner that it penetrates the textile fabric without blowing thro-ugh it and thereby causing the removing of any dressing that might have having oppositely disposed apertures, and

tubular connections between said apertures forming air passages through the steam chamber, battle plates between said metallic plates, dividing said chamber into a pluralityV of compartments each having a row of said tubular connections, passage-ways between said baille plates and said frame arranged alternately at one end and the other of the frame, whereby a Zig-Zag course will be -given the passing steam. Y

2. A drying apparatus for textile fabrics having a housing, a plurality of rollers, an endless band passing around said rollers forwcarrying the textile fabrics, and means for moving said band, a plurality of hori- Zontal shelves in the housing and a plurality of driers supported by said shelves;

said driers each comprising a frame, metallic plates secured on opposite sides of said frame forming therewith a steam tight chamber, meansV for supplying steam for said chamber, said metallic plates having oppositely disposed apertures, and tubular connections between said aperturesl forming air passages through the steam chamber, bathe plates between said metallic plates, dividing said chamber into a plurality of compartments each having a row of said tubular connections, passage-ways between said battle plates and said frame, arranged alternately at one end and the other of the frame whereby a zig-zag course will be given the passing steam.
