(Cl; ill-48) This invention'relates. to an apparatus'for carrying outp'addi'hg, dyeing; impregnatingfor like treatment witha treating, liquor (hereinafter and in the claims referred "to simply; as. padding) on cloth, yarn; or other textile; paper, or like absorbent materials in continuous length. The: term ftextil'e materials isLinten'ded to embrace'various materials. as used inthe textile industry, for ex= ample. cotton, wool, rayon; nylon, andother natural or. artificial materials; and fabrics, felt," sheets; Web's or yarns. made from" glass or synthetic. plasticmaterials: The termtextile' is not intended. to restrict the. scope of. the inventionlt' woven material." Such materials are: all hereinafter andin the claims embracediwithin the term .materials.
In the conventional'form of textile padding mangle the material in'the'form of'cloth passes through the liquorzcontain'ed "in a vessel, becoming; saturated'with theliquor; and then passes through a" nip to squeeze out'the excess liquor notrequired for the operation. The extent to which'th'eexcessiliquoris squeezed out can, within limits, be adj usted-byi the. pressure'between the nip rollers:
' In some cases a double nip is 'provided' consist ing of three rollers arranged so that the cloth first" passes'betwe'en the first. and second rollers and subsequentlybetweensthe second and .third rollers:
It is fundamental tothepperationpf'such pad.- ding mangles'that the cloth should, 7 in" its passage through theili'quor; absorbimore liquor than isiultimately'needed; the excess being squeezed out by thenip or nips: When 'the'liquor contains. particles that have anafiinity for the clothor the particles'are of such'a sizethat the cloth acts, as a partial. filter; it is evident. that the liquor squeezed'from thenips and returning to the vessel will be deficient in particles as compared. with the freshliquoriand" the efiect will be a gradual decrease'in' the concentration of particles. in the vessel. Iftheisqueezedliquor flows down the incomingcloththe danger arises. of streaks. due ..to the further absorption ofliquor on certainparts of the cloth in rivulet form and. thereby provide ing. an excessofparticlesinthat zone.
It willbe clear. that ifthe liquor squeezed from the hips can be diverted and collected in another vessel, this. efiect wilLb'e largelyovercome the only diluting efiect then being the-extent towhich the particlestend to .adhereto. the cloth during its passage through the vessel .in. excess .of the correct quantity relative. to the volume of liquor. absorbed.
However, in. most casesisuch. an arrangement woul'clbe Wastefur'as itis" usual "forthe liquor'expressed iromthenipsstillto' contain a: substantial amount of "the particles and these woulwbe wasted or. wouldrequire expensive treat'mentftorestore them'to'the desired density:
In accordance with the present inventionwe' provide: a m'ethodpf padding absorbent material in'continu'ous length'with a treating liquor, com-- prising passing the material through a liquor-bath whichis fedwith'freshliquor at substantially-the samerate as it is takenup from the batlr'by the" materia'l; and maintainingon'lyasmuch liquor'in the bathas wouldbe takerrup by thematerial in a very shorttime-ofpassagetthrough the bath; fbr exam'ple; thirty seconds;
The eff'ectof" this"diminution"inthe bath size is that within a" very "short time of 'startin'gjthe ultimate dilution hastak enpla'ce and aconditiorr of"stability has b'eenrea-ched in which the rate of; for example; particle absorption by cloth isexact- 1y balanced bytherateof input of'the --partic1es' thirouglithefresh liquor-suppl3n Any variation therefore takes placesoiely'inthe first few yards of the process and if objectionable can be over=- comeby theuse of anendcloth;

material in continuous: length with. atreating; liquormcharacterisedz by the. factthat. abath. oi. said liquor is formed between-twocoeoperatingl rollers defininga nip through .whichthe. material passes. Preferably the bath is formed at that side of the nip where the material enters the same whereby the nip automatically squeezes excess liquor from the material.
Some embodiments of the apparatus in accordance with the invention will now be described simply by way of example with reference to the accompanying drawings, in which Fig. 1 is a diagrammatic vertical section showing the hitherto conventional single nip padding apparatus.
Fig. 2 is a diagrammatic plan view showing one end of padding apparatus in accordance with the invention, Fig. 2a being a corresponding end elevation but showing the part I4 in dotted lines for clearness.
Figs. 3 and 4 are views similar to Fig. 2 but of modifications, Figs. 3a and 4a being corresponding respective end elevations but with the parts I4 and Nb shown in dotted lines for clearness.
Figs. 5, 6 and '7 are diagrammatic vertical transverse sectional elevations of three other modifications.
Fig. 8 is a perspective view of a further modiflcation.
Fig. 9 is a diagram partly in section illustrating a means for controlling the supply of treating liquor.
In the various figures like references indicate like parts.
In Fig. '1 which shows the hitherto conventional arrangement, there are two main or nip rollers ll, 12 urged together as indicated by the arrows to form a nip at 28. The material, for example, cloth, is indicated at I! and passes over guide rollers 25 through treating liquor, such as dyestuff, in a bath vessel 26 and then up through the nip at 28. As indicated at 21 the liquor squeezed out at the nip 28 runs back over the cloth and drops again into the bath.
In Figs. 2 and 2a the axes of the two nip rollers ll, I2 are in the same horizontal plane and the bath [3 of liquor is formed in the V-shaped space on the upper side of the nip, the ends of this space being closed as described below.
Each of the rollers at each end is formed with a flange I la, l2a. each defining an annular groove l lb, I2b, and a soft rubber endless belt I4 is borne in guide pulleys l and passes vertically down in line with the bath so as to fill the space between the two roller grooves and thereby seal the bath l 3 at each end. The belt I4 is of considerably greater height than width and is also made a little wider and thicker than the space defined by the two grooves, so that the rubber is squeezed sidewise against the walls of the grooves and against the roller ends. Small variations between the centres of the rollers arising from adjustments of the degree of nip will not, owing to the elasticity of the belt, prejudice the seal. The cloth I! passes vertically through the bath as shown.
The dye or other treating liquor is supplied through pipes IS on each side of the bath and extending the full width of the nip, and each pipe is provided with perforations along its length so that the liquor is supplied evenly throughout the length of the nip, that is, the width of the bath.
At least one of the rollers of the nip is rubber covered, but if very thick cloths have to be processed both rollers must be rubber covered or its equivalent so that a satisfactory seal is provided at the cloth selvedge.
The means for adjusting the supply of fresh liquor may be by manual control or alternatively by automatic means as illustrated in Fig. 9, in which an outer tube 31 dips in the liquor bath I3 and carries an inner tube 29 in which the liquor rises and falls and supports a float 38. The top of the tube 29 carries a closure 30 mounting an electrode 3! connected through leads 32 and a resistance 33 to a relay 34 adapted to actuate a liquor-feed valve 35.
In a modification the belt may be arranged to move in a vertical plane containing the nip, as indicated in chain dot lines at I492, instead of as above described in a vertical plane at right angles to the bowl axes.
In another embodiment as in Figs. 3 and 3a the ends of the bath 13 may each be sealed by a somewhat softer rubber ring Ma (shown in horizontal mid section) which fits completely around the groove in one of the rollers and may be secured therein or may be loose. In the region of the nip the ring [4a fills the space between the two opposite grooves in the manner described above. In this case the rubber or other material should be somewhat softer to allow some distortion owing to the difference in speed between the periphery of the ring and the periphery of the groove in the other bowl.
In a further embodiment as in Figs. 4 and 4a, the sealing is effected by mounting at the ends of each roller a ring lb of enlarged section of relatively soft rubber or the like, for example sponge rubber with the outer surface thereof sealed by a covering of thin rubber. The rings are secured to the respective rollers and the peripheries of the two rings at each end squash each other but they are prevented from turning into the nip proper by a guard plate l8 located just above the mp.
Alternatively, pneumatic tubular rings may be used for example of square section.
If the axis of one roller is arranged lower than another, it has been found that even with'the line joining the axes of the two rollers forming an angle of say 45 with the horizontal, it is still possible to retain at the nip a substantially static bath of liquor sufficient for the purposes of the invention.
It will be appreciated that any convenient number of nips in succession may be arranged.
For giving double impregnation to the fabric, three rollers H, l2, l2a may be arranged, as in Fig. 5, with the axes of the first and last in the same vertical plane and the axis of the middle roller l2 staggered relative to the other two, the lines joining the axis of the middle roller with those of the other two rollers being at 45 to the horizontal. The cloth I! passes downwardly to the first nip bath I 3 and then around a guide roller [9 at and enters the lower nip bath 13a. Liquor-feeding pipes l8 are provided at each nip bath above and below the cloth.
In some cases it may be necessary to locate two adjacent rollers with their axes in the same vertical plane, thus rendering it impossible to maintain a static bath. In such case, however, referring to Fig. 6, a shallow trough 20 may be provided to act as a bath vessel and through ,into the nipr and; a ,1iq11OI"ib&th isuthus formed .at

In a further embodiment, in whioh the axes of the two bowls are in the same horizontal plane, as shown in Fig.--8,--an endless-rubber blanket 22 is passed round each of the rollers, each blanket being tensioned-by a--jockey=or guide roller 24. :fijaid, ioekey rollers-are smaller inadiam'eter than the rollers, and the axis of each is arranged substantially in the same plane as the ,axis of the associated roller. The liquor 'is fed into the troughor nip between the-blankets 22 'and'th-e inter-blanket trough 'is -sealed at each si' d e by raised tires "2-3 provided at bot-h edges of each blanket an'd formed either of soft sponge rubber or'of air inflated rubber. Ea'eht-ype is squeezed hard against the co-operating tyre on the other blanket and in this way forms the requisite seal. The distance between the two jockey rollers can be adjusted to vary the width of the trough of liquor.
