APPARATUS FOR DYEING AND DRYING TISSUEAND OTHER PAPER.

SPECIFICATION forming part of Letters Patent No. 397,069, dated January 29, 1889.

Application filed March 7, 1888- Serial No. 266,479. (No model.)

To all whom it may concern.-

Be it known that I, RALPH CROMPTON, a subject of the Queen of Great Britain, and a resident of Elton, near Bury, in the county of Lancaster, England, manufacturer, have invented certain new and useful Improvements in Apparatus for Dyeing Tissue and other Paper, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improved apparatus for treating tissue and other paper in continuous rolls, after manufacture, with various solutions, chemicals, coloring-matter or dyes, and then drying the same. The invention is applicable to the manufacture of tracing-paper, water-proof paper, cheek-paper, and almost any kind that requires chemical treatment after manufacture.

The invention may also be applied to the paper-making machine, in which case the coloring or inordanting rolls may be placed in a suitable position between the dryingcylinders or between two sets of drying-cyliniilers, or replacing the so-called intermediate calender, the paper being dried, or nearly so, by the first set of cylinders, and, after being treated, finally dried by the second set of cylinders.

Hitherto it has only been possible to treat tissues and thin papers in the web with solutions at considerable expense, owingto the great waste of materials used through the paper breaking so frequently and other causes. By my invention it is possible to impregnate a roll of tissue-paper with a chemical solution or dye and dry the Jame, (without injury to the colors,) and without any appreciable waste of paper, solution, or dye. Brighter and darker shades may be prod need by my apparatus than by any other.

According to this invention, I pass the tissue or other paper in. a vertical. direction, or nearly so, down between two messing-rolls covered with felt, cloth, or other suitable porous substance, and suitably supplied with dye and serving to more or less impregnate the paper with the coloring-matter, while removing the surplus of same. For some kinds of paper the rolls may be covered with rubher or other similar substance and used without the felt covering, or one metal roll and one rubber-covered roll maybe used together. It will thus be understood that the dyeing, pressing, and removing the surplus solution are performed in one operation and byone pair of rolls. I may by similar means apply a mordant to the tissue or other paper before or after applying the die, and by preference in the same machine.

By the aforesaid arrangement I avoid the need for special means of support to the wet tissue-paper. The paper thus far treated is then passed unsupported through a drying apparatus arranged close to the pressing-rolls or (in case of mordanting as well as dyeing) the last pair of pressing-rolls.

Figure 1 of the accompanying drawings is a part sectional elevation of one form of apparatus for mordanting or dyeing tissue and other paper. Fig. 2 is a similar view of the principal parts of another form of the apparatus; and Figs. 2 $13 and 3 form a similar view of a complete apparatus for mordanting, dyeing, and drying tissue and other paper. The figure is shown in continuation on Sheets 2, 3, a, and 5, one part being shown on each sheet, beginning on the left and continuing on toward the right.

In the form of apparatus shown in Fig. 1 I employ two metal or wood rollers, C O, covered with felt, cloth, or other suitable absorbent material, or two rubber-covered rollers, or one metal and one rubber-covered roller. These rollers are placed at or about the same level, or one raised slightly above the other. The rolls are mounted in suitable frames with screw or lever pressure arrangement at each end, and are caused to revolve inward. The I solution for mordanting or chemically treat= ing or the dye for coloringis run between the nip or point of contact of the rollers C C from a tank, F, by the pipe G, terminating in the perforated pipe G, or other suitable appliance placed above, or it may, as shown in the part elevation, Fig. 2, be supplied to the feltcovcred rollers C C by means of feed-rollers N N, revolving in dye-troughs 0 O, or by any other suitable methods.

The paper, A, to betreated or dyed is drawn oil from a continuous roll, and by preference passed over a guide-roll, I placed above the lfelt-eovered rollers (f. It then enters be tween the nip olf the p1.'essurerollers C By this means the paper passes through a small iplantity of solution lying just above the nip ol' the pressure-rollers, and immediately afterward receives the pressure of the rollers and becomes impregnated. I thus do away with the neel; sity .l'or emlless supporiing-bands for the wet tissue-paper. The surplus sohr tion or dye runs oil at each end of the press ure-rolls and is caught by a reeeiveror trough, II, placed underneath, from which it flows into the main tank, so that it maybe used over again. The bulk of the solution in Fig. 1. placed in a doubh-i-cased tank, I), which may be steam-heated or not below the pressure-rollers, and is pumped up, for instance, by a pump, E, and pipe E into a small box, F, abm'e,lron1 which it is supplied to the rollers, the box having an overflowpipe, 1, into the main tank I), so as to keep up a regular pressure and make the action continual.

The solution need notbc run onto the pressure-rollers in such quantities as to form a bath above the nip, but just sullieient may be used to moisten the felt covers 011 the rollers, the result obtained being almost the same. Felt-('(wered doctors 1 P, as shown in Fig. i, or other suitable means, may be applied to the pressure-rolls to keep back the surplus liquid.

'lhepressure on the ends of the rollers may be so regulated. as not to press the dye right lhrough the paper, but may he worked to color it on the surface only or to any desired degree of penetration.

I11 eoloringI sonnetimes employ two pairs of :l'elt, rubber, or other covered rollers, as shown in Figs. 3, 3, 3, and 3, which form a side view of a (@OlllPlGiiG mordanting, dyeing, and drying apparatus, the one pair Q Q to impart the mordant and the other pair, 0 C, the dye to the paper. Sometimes I dry the paper after mordanting and before coloring, and I prefer to do this by a stea111 -heated cylinder, I], placed between or above the two pairs oi. pressing-rolls and provided with the usual endless lelt, M. Alter the paper has pa 1d through the nip ol the pressure-rollers 1 is taken oft at one side and conducted unsupported direct to a drying appliance consisting, by 'n-el'erenee, of a system of air-drinns (with interior fans) and s"ea1n-l1eated dryingylinders, (fitted in the usual manner with d rying-l'elts).

K K are the air-drums, and L L the steamheated drying-cylinders, with the usual dryingfelts, M. By this arrangement the paper may, if desired, be dried entirely by air, (the cylinders I1 beingthen used cold and serving merely to keep the paper flat and tree from cocl 'les,) or may be dried partly by the airdrums and partly by the steanrheated cylinders. 13y drying thus by the air-drums and steam-cylinders combined I greatly preseiwe the color and add to the brillianey of the tints; but for some tints I find it better to use the cylinders eold. After the paper has passed through the drying apparatus it is reeled 11p in the ordinary manner, passingtwer the roll It to the reel-shaft T.

The lelts M are used to simply press the 1a 1er a ainst the e dinder L to absorb a 101'- tion ol the moisture and keep the web ot' paper ii at while the moisture is being expelled by the heat of the cylinder, said felts being made of thick woolen nmlterial.

The air-dru1ns K are skeleton. eyli nders with wooden ribs across to SUPPO'll) the paper web, and within said cylinders are arranged fans to blow airagainst the web oilj'paper, and thus assist in drying the same, so as to avoid the necessity of applying great heat.
