.APPARATUS FOR WELDING INK AND cELLULosE TISSUE original Fil'ed sept. 15, 19:55



Application september 15, 1933, serial No. 689,674 I'tenewed March 30, 1936 1 Claim.

This invention relates to apparatus and processes for drying sheets of freshly printed fabrics, whereby oisetting and smutting is prevented when applying differently colored ink thereon in quick succession, and has particular reference to sheets of non-absorbent material such, for instance, as cellulose tissue, glassine etc.

In printing on ordinary paper, any excess moisture in the ink is quickly absorbed by the paper and its bibulous character is commonly enhanced by passing the sheets through a heated zone, produced by electricity or a gas flame, and eventually ydeposited in a container in such a manner'that a film of air intervenes the sucl5 cessive sheets. Inasmuch as only the printed surface of the paper is dry and `not the paper itself, sheetsof absorbent material must be inserted between printed sheets to prevent *blurring. i,

A thorough drying of print and web is particularly important Where a condition of complete dryness must exist, as in multi-colored printing before the sheets reach the next printing cylinder.

However, when printing on non-absorbent material other means must be found to dissipate the moisture in the ink, so that only the pigment remains on the surface in a completely dry condition, and it is the principal object of this invention to accomplish that effect.

A further feature of this invention resides in the provision of means for imparting heat directly to the surface of a freshly printed web during its travel by drawing the ink through the 35 fabric, and means whereby the solvents in the ink are withdrawn by suction pumps, the suction heads of which are arranged directly opposite the heat producing rolls.

Another purpose of the invention is the provision of a drying apparatus consisting of a stationary heating element in a rotatable housing of heat conductive material and light weight. Another aim of the invention is the provision of an apparatus of 'this character which can be used in connection with ordinary printing presses of the cylinder or at bed type.

Another feature of the invention is to provide means for printing on moisture-proof cellulose tissue, where it is necessary for the ink to penetrate the wax coating of the paper, to form a firm weld between ink and paper.

A yet further aim is the provision of an apparatus of this character consisting of few and simpleparts', being simple and effective in operation and highly durable.

These several lconsequential and characteristic features are achieved by the novel and practical construction of parts hereinafter described fand shown in the accompanying drawing, constituting an essential part of this'dlsclosure, and 5 in which:

Figure 1 is a schematic view of an embodiment of the invention, certain parts being inside elevation and others in section.

Figure 2 is a longitudinal sectional view of the l10 heat engendering roll.

Figure 3 is a transverse sectional view, taken on line 3--3 of Figure 2. l

Figure 4 is a fragmentary side elevational view of the heating roll and heat controlling element, l5 the housing being removed.

Figure 5 is an enlarged sectional view illustrating the relation of parts when in operation.

Figure 6 is a diagrammatic view Iof the heat control element.

In Figure 1 of the drawing, two stands, respectively designated by the numerals lil- II are shown, .these stands being secured in spaced relation on a floor, to support freely rotatable rolls, on which are mounted a coiled web I2.

This web is the material on which the printing is to be received, and it is to be understood that one of the rolls, as that in. the stand Il, is provided lwith a driving means (not shown) and the other is actuated by movement of the 30 web as it is drawn from it.

Spaced intermediate the stands are ink contain- ,ers Ill-I5, having mounted in them dispensing cylinders lG-l'l and thereabove, in vertical registration with their axis are impression rolls 35 |8-l9, the web being between the rolls and the cylinders. one set of which supplies ink of one color and the other another color.

AThe web l2 is directed upwardly from the rolls I8-I9 to pass under guide rollers 2li-2| and over 40 similar rollers 22-23, whereby the web is subject to atmospheric drying. The guide rollers may be eliminated however, as atmospheric drying becomes unnecessary since the heating element leaves the web in a thoroughly dry condi- 45 tion.

Rearwardly adjacent the ink containers I4-I5 are platforms 24--25 on which are xed motors 26--21 directly geared to suction pumps 28-29 having expanded inlet heads 303I suited in 50 shape and disposed closely adjacent the under surface of the web which is inclined upwardly after leaving the printing cylinders |6-l1.

Pairs of support arms 32--33 are secured to the frame of the apparatus (not shown) and xed to 55 extend between each pair of arms is a tube 35 provided at its extending ends with expanded caps 36 having removable covers 3l. These caps also have lateral bosses 38 in which are set tubes 39.

Fixed on the tube 35 adacently inward of the arms 32 are rigid washers 40 of low heat conductivity to prevent the heat from penetrating the housing of the roller laterally. Also fixed on tube 35 are the inner elements of annular ball bearings 4l their outer elements being set in collars 42 provided with caps 43.

The collars or heads 42 are clear of the tube 35 and are held from longitudinal movement by the washers against which they make contact at their inner sides.

A tubular housing 45 is fixed in annular recesses at the inner ends of the collars d2 to extend therebetween, this tube being of light weight, heat conductive material and of very small diameter. Aluminum is one of the materials suitable for the housing. Due to its mounting the housing is readily rotatable by the web with which it makes frictional contact on the side opposite the freshly inked face of the web.

Mounted on the tube 35, intermediate the heads 42, and locked in position by clamp nuts 46, are a series of dielectric discs lhsuch as mica, having between them spacers it of like material.

Set in one of the outer discs Ml' are a pair of binding posts 49-50 to which are secured electric conductors 5I-52 passing out through the tube and pipe 39 after being encased in the housing 3b.

In Figure 6 is illustrated a simple heat control means comprising a switch 5@ to which are con nected the heating coils 5&1. It will be apparent that the pointer 5l on switch may he turned to oil, low, medium or "high selectively, and that the temperature within the roller will vary accordingly.

In order to print upon waxed or moisture-proof fabric it is necessary to melt the wax coating upon the cellulose tissue before printing is done thereon. If this is not done, the ink will not penetrate the waxed surface, and the impression will not last. In order to obtain the desired result, a heating element without'suction pump, is secured forwardly adjacent each printing cylinder. Thus the waxed cellulose tissue will be heated before ink is applied thereon.

While certain preferred embodiments of this device have been shown and described, it will be understood that changes in form, arrangements, proportions, sizes and other details thereof may be made without departing from the scope of the invention as defined in the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

An apparatus for drying moisture-proof cellulose tissue comprising a pair of stands provided with means for supporting a web therebetween, n

means for making an ink impression on said web when moving from one stand to the other; two heated rollers of small diameter and light weight in direct frictional contact with and actuated by said web, one arranged to heat the web before an ink impression is made thereon, and the other to dry the web after the ink impression has been made, and manually operable means for selectively controlling the degree of heat in said rollers.
