Y., ASSIGNOR '10 DYEING PROCESSES CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK ART or TREATING YARN Application filed March 11, 1927. Serial No. 174,597.

The present invention relates to the art of treating yarn and similar textile materials with dyeing or other treating fluids while in the form of a cop, bobbin, spool, cheese or 6 other form of package, and it relates more especially to the preparation of the package preliminarily to the dyeing or other treatment whereby uniformity in density of the yarn in a plurality of packages will be obtained, thereby insuring even and thorough dyeing or other treatment of all the yarn in all of the packages.

According to the present invention, each yarn package is wound on a pervious holder which preferably is incompressible axially,

but has a yarn supporting surface'of relatively small area in contact with the yarn at the center of the package; each yarn pack age containing its holder is placed between a pair of heads which are adapted to bear endwise against the ends of the respective package but are capable of'movement axially of the ends of the respective holder; and a suitable number 0 the packages are assembled end to end with their holders in alinement and abutting endwise and their compression heads arranged to act in pairs on the respective packages interposed between them, and axial compression is applied to the end heads and maintained thereon. The endwise compression thus exerted on the series or setof packages is transmitted uniformly to all the packages of the series, as each package is capable of moving longitudinally on or accommodating itself to its holder under such compression while the compression heads are unrestrained by the holders, and, hence, the endwise compression applied to the outermost heads will be equalized among the various packages of the series, 1nsuring equal axial compression of each package and thus producing the requisite amount of compression of the yarn composing each.

package to produce uniform permeability thereof, and, in consequence, even dyeing or other treatment of the yarn by the dyeing or other treating fluid forced through it from its center outwardly, or vice versa, may be attained during the subsequent dyeing or other treatment.

By arranging each yarn package of the series between a pair of cooperative compres sion heads which are capable of movement independently of the yarn holders, the several yarn packages of the series will be properly compressed without requiring the use of a series of intermediate trays, which, as heretofore used, have been heavy and involved slow and diflicult handling.

1 To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts, all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing Figure 1 represents a longitudinal sectional view of a series ofyarn packages assembled and compressed in accordance with the preferred embodiment of the present invention;

Figure 2 is a detail sectional view of one of the compression heads employed in the arrangement shown in Fig. 1;

Figure 3 represents, on an enlarged scale, a top plan or end view of the assembly shown in Figure 1;

Figure 4 is a view of a part of the structure showing means which may be used in some pression of yarn or similar textile materials to secure uniform permeability thereof to liquids, gases or other treating fluids, al-

though the invention is particularly adapted I for the preparation of yarn packages in the form of cops, bobbins, spools, cheeses and textile film in the form of roving tops etc. or the like for dyeing while in such form by forc lng dyeing liquor through'the package while the sameis compressed in a manner which will insure uniform density of the packages,

and, in consequence, even and uniform dyeing. The'preferred embodiment of'the invention will be hereinafter described in detail in connection with the accompanying drawing, but it will be understood other equivalent embodiments of the invention are contemplated, and such will be included within the scope of the claims.

In the present instance, A represents yard packages which may be of substantially cylindrical or other form and consist of yarn or other textile thread or textile materials on tops roving etc. each of which is wound upon a pervious holder l'by which is meant a holder which permits flow of treating fluid radially through the holder from its interior to its exterior yarn supportin surfaces, orwvice versa, or each yard pac age may be first wound upon a tube or other suitable temporary holder and then transferred to such a pervious holder. Pervious holders of different kinds may be used, it being desirable to employ a holder which offers openings of suflicient aggregate area to the interior of the yarn package to permit free flow of the dyeing liquor or other treating fluid from the interior of the holder into the package, or vice versa, and the invention enables pervious holders to be used which are incompressible axially and present peripheral yarn supporting surfaces of relatively small area, and are without obstruction or indentation from end to end of the holder, so that the yarn package is capable of movement longitudinally on the holder. The pervious holder shown in the present instance is of a type shown and described in my prior application Serial No. 80,316, filed January 9, 1926, which reference is made for a complete illustration and description of its construction. For the present purposes, it is believed suflicient to describe this holder as comprising a number of circumferentially spacedlongitudinally extending yarn-supporting members 2 which form flutes between them and are parallel so that the holder will be of equal diameter from end to end and no obstructions exist which would interfere with the longitudinal movement of the yard package with respect to the holder, the latter being axially hollow as indicated at 2 for the flow of the dye liquor axially therethrough. The yarn-supporting members are suitably spaced to permit the radial passage of the dye liquor or other treating fluid through slots 2 formed between them, and the ends of the supporting members are united by inner and outer bands 3 and 4, these bands being preferably of reduced diameter with. respect to that of the portion of the holder formed by the supporting members. The yarn may either be wound initially upon such a holder, or it may be wound first upon a paper tube or other temporary form of holder which is of greater diameter than the pervious holder, and then wise displacement of the yarn package while the holders are placed end to end.

Each yarn package, according to the present invention, is compressed axially while a suitable number of the packages are arranged endwise in a-series. As shown, it is preferable to employ for this purpose a pair of top and bottom or end compression heads 5 and a suitable number of intermediate compression heads 5a. These compression heads are preferably of conical form and of a diameter approximately equal to that of the yarn packages with which they are to cooperate. The end heads 5 are formed with tubular hubs 6 and the intermediate compression heads are formed also with tubular hubs So although the hubs 6a are common to a pair of the intermediate compression heads and serve to connect them. It will be understood of the compression heads are sufliciently large to accommodate or fit loosely over the ends of the pervious holders, and the compression heads are preferably so proportioned that when a series of yarn packages containing the pervious holders are assembled, the ends of the pervious holders will abut against one another while the compression heads bear against the ends of the yarn packages and may operate to apply axial compression thereon. v

The series of yarn packages containing the pervious holders may be assembled in endwise relation with the end and intermediate compression heads applied substantially as shown in Figure 1, and compression is applied to and maintained upon the yarn pa'ckages by endwise compression exerted upon the end compression heads 5. Different means may be employed for applying this compression, a pair of plates 7 being shown for this purpose in the present instance, each plate fitting over the tubular hub 6 of the respective end compression head and bearing against the latter, and a suitable number of threaded or other tensioning rods 8 connect the plates, the plates being drawn together or toward one another by suitable manipulation of the nuts 9 on the tensioning rods, and after the requisite amount of compression has been applied, the plates and their tensioning rods will maintain such compression.

Compression exerted upon the end compression heads will be transmitted uniformly to all of the yarn packages in the series. Whilethe end heads 5 will act directly upon the end packages to compress them, these packages may move axially on theirholders toward the intermediate packages, thus transferring the compression from the end packages to the intermediate compression compression to the respective intermediate packages. It will be understood that this uniform distribution of the axial compressing force will take place throughout the series of packages irrespective of the number of packages comprising the series, the equalizing of the compression among all of the packages being permitted to take place by the ability of the packages to shift longitudinally on their respective holders and thus accommodate themselves to the compression forces acting thereon, and hence equalize the compression acting in opposite directions upon each package. The accommodating of the compression heads to the compression forces acting on each package is not interfered with by the holders as the tubular hubs of the compression heads fit loosely over the ends of the holders and may, if necessary, pass more or less onto the holders.

It may be found desirable in some cases to employ means for limiting the compression imposed upon one or more of the ackages. Such a limiting device is shown in ig. 4 to 6, it comprising for example, a tube 10 one or more of which may be placed on each-of the rods 8 so that they are shiftable longitudinally and also rotatable thereon, each tube having suitably spaced lugs 11 projecting from a side thereof near its upper and lower ends. When it is desired to limit the compression imposed on any one or more of the packages in the assembly, the tubes 10 are shifted along the rods 8 to bring them opposite to the package or packages whose compression is or are to be limited, and the tubes are rotated to bring the lugs 11 'thereon into position between the heads 5a containin such package or packages between them. en the packages are compressed, these lugs on the hmiting devices will limit the relative movement of these heads toward one another and thereby limit the degree of compression imposed ,onsuchpackage or packages.

The assembled packages'compressed as described may be placed in any suitable dyeing or'other apparatus to efiect the dyelng or treatment of the yarn. For example, they may be placed in a dyeing apparatus of the same general type as that shown in the prior patent of myself and F. H. Daniel, No. 1,052,817, granted February 11, 1913. In lacing the assembled and compressed pac ages in a machine of that type, the package assemblies, such as shown n Fig ure 1, are placed in uprlght. poslt on between the top and bottom plates of the kier or treating chamber andthe tubular hubs 6 of the top and bottom compres sion heads, or either one of them may form a fluid-tightfit with one or the other of these plates so that treating fluid may be forced into the packages through one or the other or both of the hubs of the end compresuniform pressure of the latter while acting on the different yarn packages of the series; or the direction of flow of the treating fluid may be reversed so that it will pass from the outside of the yarn packages inwardly to the centers thereof and the treating fluid may then be withdrawn through one or both of the tubular hubs of the end compression heads. By producing an equalized axial compression upon each of the yarn packages of the series, in the manner hereinbefore described, the yarn in all of the packages will be of substantially the same density, and, moreover, the density of the yarn in each package will be substantially uniform, in consequence, uniform permeability of the yarn in all of the packages is obtained by compressing the packages in the manner bled with respect to the compression heads,

the previous holders may then be removed by endwise displacement from the packages and the latter will then be ready for further disposition.

The present invention enables uniform distributiorrof axial compression to be produced and, maintaind ,in a series or plurality of yarn packages sothat uniform permeability ofthe yarn in all of the packages of the series will be attained, and, moreover, the provision of the intermediate compression heads enables fluid-tightjoints to be obtained eflectively between the ends of the different packages of the series, underthe compression applied to the end compression heads, thus avoiding leakage which has been likely to occur where it has been attempted to form such joints by direct contact between the ends of adjacent packages. While the invention enables the results hereinbefore described to be attained with yarn packages while they are mounted on pervious holders which are non-compressible axially and possess many practical advantages over axially ers and when so used, the results hereinbefore referred to will be attained.

I claim as my invention l. The improvement in preparing yarn for treatment with fluids which comprises assembling in axial alinement a. plurality of hollow yarn packages in wound form and containing axially hollow, radially pervious, longitudinally fluted holders on which the respective packages are freely movable axially placing joint-forming heads between the ends of adjacent packages, applying axial compression to the end packages of the series thus formed, causing such compression to be'distributed and equalized throughout all the packages by movement of the packages axially on their respective holders, thereby producing uniform density of the yarn in all the packages of the series and forming fluidtight joints between the ends of the packages and the joint-forming heads, and maintaining such end compression on the series of packages.
