rarnn-nnrnse rraonrnn' To allwhomz't may concern: 1 Be it known that l, CLARE Nnnson, a citi Kings, State of New York, have invented certainnew: and useful Improvements in Paper-Drying Machines;-
' and I dohe-reby declare the following to be a tull,.c1ear,-and exact description of the invention, such'as will enable others skilled.
in the art to which it appertainsto make and use the same. v, Y
-My invention s an improvement in dry ing machines, andrelates particularly to an improved machine for drying paper, after the methods set forth it has been coated b V in application Seria No. 24:1,102, filed June 21, 1918, and application, Serial No. 4192332, a film of filed August. It, 1921.
In carrying out these methods, moisture is first applied to one face of the I sheet, andthe said'fa'ce is afterwards s at tered with specks of color,-one or more co ors being used, and'the colors'areapplied in succession to the same area, as ,in application, Serial No. 241,102, filed June 21, 1918, or simultaneously to the same area, as in application, Serial No. $92,932 filed Aug. 17,
1921. It is desirable in order to attain attractive andartistic effects, that the colors be. set-quickly afterblending, that is that the webot paper be quickly dried, thereby avoiding the danger of the colors running, as well as the need for supporting the. paper for a relatively'long time in testoons, as is the usual practice. In dryingmachines of the character shown and described in applications, Serial No. 475,795 filed June 7, 1921,
and Serial No. 477 ,422 filed June 14:, 1921, a
casing, or a series of casings, is provided, through which the coatedpaper 1s. drawn, moving on or with a suitable support, arranged within-the casing, and extending the full length thereof. Air is circulated through the casing, and heating meansis arranged within the casing for heating the air as it circulates, to dry the paper. The casrugs are rectangular in transverse cross-section,jproviding thusan internal, capacity in excess of that required for the .proper circulation of the an and the passage of the paper. The angles between the walls of the casing provide dead air pockets which impede the rapid changing of the air es 'sential to quick drying, and-the shape of the casing results in an appreciable waste ofheat by convection and radiation.
The object of the present invention is to provide a-construction of casing, such that heat losses through convection and radiation are greatly lessened, and all obstruction to the rapid and complete changing of the air is eliminated, and wherein the paper .is quickly and thoroughly dried in a relacasing is provided with inlet and outlet passages2 and 3 at its opposite ends, through which the web't of. paper may enter and leave the casing. lhe web of paper in its movement through the casing is supported by .the upper run of an endless belt 5, oil foraminous material, as for instance wire cloth. l he upper run of the belt extends through thepassages 2 and 3, and is supported by rollers '6 journaled transversely of the casing, the rollers being arranged at suitable intervals to properly support the run and the web. The lower run of the belt is below the casing, and outside of the casing the belt passes over rollers 7 arranged in suchmanner that the belt does not engage the casing, and may move freely with the paper web as it passes through the casing. Below the casing tension rollers 8 are arranged, for
tensioning the belt, and the web is drawn through the casing'1,-by means of rollers 9 which grip the web beyond the casing.
Suitable means is arranged within the. casing for heating the air, the said means being in the present instance, electrically controlled heatin means 10. The heatin units are arranged adjacent to the outlet en of the casing, and extend from the said outlet end about two-thirds the'length of the casing. -When the dryer is used for drying ,coated paper, for which it is especially do vertical section able length and cross-section, and the said lot signed, the heating units need be arranged above the web only. a paper web, as it leaves the wet end of a paper making machine, the heating means willbe arranged above and below the web. Thedryer units may be arranged in the manner shown and described in application 1 Serial No. 475,795, filed June 7 1921., that is in series, one above the other, or they may be arranged in series in alinement one with the other, or a single unit may be used. Means is, .provided for circulating air through the ing means, to dry theweb, and to remove the vapor as it forms. The said means comthe casings are rectangular in-qtranverse cross-sections: This arrangement provides corners .which' form dead air pockets, for
.the collection of vapor, which condenses at such points. In order to eliminate these pockets, Imake the casing oval, or elliptical in cross-section as shown in- Figure 2, and the top of the casing is preferably of copwhich is polished on its inner face. The
- polished, arched shape act's'as a reflector,
throwing the heat onto the upper face of the web, thus utilizing. the heat provided by the heating means to the best possible advantage. The particular shape of the interior of the casing, oflers the least possible im pediment to the free circulation of air, and eliminates all pockets where vapor laden air might collect. A v
If it is desired to constrain the web to take an arched formation as it passes through the dryer unit, as is desirable in treating certain grades of paper,'as 'for instance heavy paper board, the alternative arra'n e'ment shown in Figure 3 may be used. n this construction, the casing 16, which is of the same cross-section as that of Figure 1,.is arched longitudinally, so that an arched formation is given'to. the web during its passage through the dryer. In such construction, the Web is supported by the belt 17. of foraminous material, whose upper run passes longitudinally of the -'casing, being supported by rollers '18, to provide the arched formation. The web 19 is drawn through the casing by rollers '20, and the-- heating means is in the form of electrical units 21, arranged above the web, in the same manner as the heating means 10 is WVhen used for drying v casing to be heated by the heatarranged inthe casing oval form is especially desirable forfdry ng a paper web as it comes from the wet-end of a paper .m'aking machine, the top and the .bottom of the casing actingas reflectors. In Figures land 5 there is'shown a construction whereinthetop E21 of the cas ing 224 arched transversely. As shown 1. The elliptical or more particularly in Figure 5, the bottom.
of the casing is flat and plane. The webin its passage through the casing is supported by rods '23, Which extend'longitudinally of the casing, in sp'acedrelation, the paper Web 24 resting.
The Web is moved through the casing, by a pair of rollers 25, and the, heating means 26, electrically controlled in tl'IG'PIGSQDtlIP directly on the rodsstance, are arranged in the same manner as v in Figures 1 and 3. In each construction,
the top of-the casing is'preferably of copper, or copper lined, and highly polished, to provide for a maximum of reflection. Thus the top is a reflector, and cooperates with the source of he,at, which is a source of radiant heat, reflecting the same upon the -P@P I-claim: "1.
