3 Claims.

The present application relates toa machine and process for handling textile materials and particularly relates to a machine and process for handling rayon cakes to enable wet processing thereof. H 1

In many textile yarns, fibers-or threads are produced or readily handled in the form of closely wound annular masses, a's on cones or bobbins,

and it is desirable to treat or process these masses without unwinding them into skein form, and it is an object of the present invention to provide a method and means for treating such annular masses of yarn to 'enable them to be washed, desulphurized, degummed, bleached, sized, dyed and lS'dried all without the necessity of unwinding the mass of yarn or textile material and with assurance that the entire mass of material will be thoroughly and uniformly treated to the desired extent.

Although not restricted thereto, the present invention has a particular application to rayon cakes, in which rayon yarn is originally obtained as an annular frustro-conical mass after ithas been precipitated and spun in pots and it is a further object of the present invention to provide an improved process and method which will .enable the wet processing of' such rayon-cakes to accomplish the various ends as above described, which process and means may be readily utilized with assurance that the processing will take place uniformly throughout the rayon mass.

Another object is tofprovide a method and means enabling the wet treatment of rayon cakes with assurance that the delicate fibers will not be admission of treating fluids to the interior of the cake or extraction of fluids therefrom.

Preferably, the liner consists of an overlapping corrugated frustro-conical sheet which is perforated and which may be conveniently made of 7 thin gauge metal and it is most desirably coated with rubber to prevent injury to .delicate rayon fibers. l

To expand this overlapping sheet metal device there may be inserted a corresponding conical frame or skeleton member with a'series' of ribs, the cooperation of the ribs with the corrugations of the liner causing expansion of the liner ;to tightly grip the interior of the cake.

A plurality of "these cakes so held maybepo sitioned upon a horizontal or vertical spindleand separated by plates, the plates being most desirably provided with passages so that various: treating fluids may be forced interiorly of the' horizontal stack and forced-outwardly of the per forations of the sheet metal liner and outwardly through the rayon cake; or on thefoth'er hand, 7

the fluid may be drawn ;inwardly-through'the rayon cake into the interior or the'horizontal stack of said cakes. f Y W 1 By alternately forcing the liquids ou wardly through the cakes an'd by drawing them inwardlythrough the cakes, aseries of treatments' 'may be carried out, assuringmost satisfactory processing of the indiviclual fibers in saidcakes.

' The various spindles'carrying the-cakes may be arranged on a support structure whicnmay peplaced in a tank orliner 'for treating purposes. The above andoth'er objects will appear more clearly from the following 'detailed description When taken in connection with the accompanying drawings, which illustrate a preferred "embodiment of the inventive idea.

devices of Figures 5 and 6 in a tank or liner Figure 8 is a transverse cross sectional view"- upon the line 8-8 of Figure 7. V

Referring to Figures 1 to 4, the rayon cake A is adapted to receive the expandible liner B which is in turn expanded loy the expander frame C.

The rayon cake A is shown'inthefrustro-conical; form in which'it is usually produced in pottspine ning machines.

. 1 v v Figure '7 is a side sectional of assembly of the sided element being illustratively shown).

post may carry 24 of the stacks S, each consist-.

The expandible liner B is made of a corrugated sheet of metal i0, preferably provided with a metal coating or plastic covering and it is noted it overlaps as indicated at l l.

The entire circumference of the liner B is provided with spaced perforations I2 through which liquid may be supplied through the cake A.

The expander C consists of two end cross members I3, [4 which are centrally provided with the openings l5, said cross members supporting the end rings l6, ll. Extending between the rings I6, I! on the outside of the expander C are the rungs I8 having ridges H! which are received in the corrugations 20 of the liner B to expand said liner B tightly within the interior of the cake A.

In Figure 2 the liner B and expander C are in dicated as in position. Theassembly is carried out by first placing the liner B which is of smaller dimension than the cake A into the interior 2i thereof, as indicated in Figure 1. The expander C is then inserted within the liner B to expand said liner to tightly press the interior of the cake A.

Preferably, the expander C may be made of hard rubber or a similar plastic material, both the liner Band expander C being of such construction as not to injure the rayon fibers in the cake A.

The unit as shown in Figure 2 is a compact one and may be conveniently assembled upon a horizontal spindle 22 attached to a spider 28 extending across the opening 3| in the support 23 as indicated in Figures and 6.

As shown in Figures 5 and 6, stacks S of units AB-C may be built up on the spindles 22.

The spindle 22 extends through the holes in the frames l3 and M of the expander C and the various units A-BC of Figure 2 are separated by the plates 24, which are provided with recesses or openings 25 to permit a treating fluid to pass into or out of the interiors .2l of the rayon cakes A.

The end plate 26 is devoid of openings so that all liquids will have to flow through the rayon cakes A toward or from the interiors 2 l.

The entire stack S is clamped together on the spindle between the head nut member 21 and the end nut 30, the head nut 21 screwing on to the threaded end portion 29 of the spindle 22 and the nut 30 being fixed upon the inner end of said spindle.

Through the opening 3| fluidlpressure or vacuum may be applied to the interiors 3| of the stack 5 as shown in Figures 5 and 6, the entire stack being preferably immersed in a vat or tank of treating fluid as shown in Figures '7 and 8.

. As'shown in Figures 7 and 8, the member 23 may take the form of a polygonal post (a six- This ing of three units 'ABC.

The post 23 is positioned within the tank 50 having the cover 5| with hinge 52 and the locking or clamping means 53. The tank 50 is supported on the legs 54.

The post 23 at its upper end is provided with the ring 55 enabling it to be lifted out of the tank 50 and at its lower end it is provided with the conical connecting nipple 56 received in the conical socket 51.

The

pipes

58 and 59 may respectively or alternately be utilizedto feed fluid into and/or remove fluid from the tank 50 as indicat d y e arrows 60 and 6|, by alternate or successive application of vacuum or pressure.

The treating fluid may be a washing fluid, a desulphurizing fluid, a bleaching fluid, a dyeing fluid, a sizing fluid, a degumming fluid, heated air or a finish fluid and successive treatments with these fluids may be carried on.

If desired, warm air may also be forced or drawn through the rayon cakes A to dry the same.

By using the arrangement and method previously described, it is possible to treat the cakes in the various methods disclosed with assurance that the rayon will be thoroughly treated and with further assurance that the delicate fibers thereof will not be injured.

As stated before, the spindle 22, the expander C and the liner B may all be coated with or made of a plastic material, such as rubber, which will not be attacked by the treating liquids.

The assembly, ABC, as indicated in Figure 2 after the liquid treatment or before the liquid treatment, may also be' utilized for creels and warping machines or to fit over the yarn holder pins on winding or spooling machines.

The nut 21, shown in Figures 5 and 6 may be provided with quick acting breach lock.

The working of this device is as follows:

When the cake 4 is finished in the pot of the spinning machine, and removed therefrom the liner B is placed inside of the cake A. This can be accomplished by this device without damaging the inside wall of the cake, because the design of this holder is so arranged that there is about A; to 1 3-" or more of clearance between the liner and the inside wall of the cake.

After this is accomplished, expander C is in- I serted into the inside of liner B and by pressing expander C down into the grooves of the liner B, the latter consequently will be expanded towards the inside wall of the cake.

The grooves and ridges of the corrugated cake holder will create a uniform expansion force on the inside wall of the rayon cake, thereby opening up the wind of the cake, which will help greatly the circulation of the processing liquors.

Stops for the expander C may be provided inside of some of the corrugations of liner B to limit the expansion of the liner.

Theunits may then be assembled as shown in Figures 5, 6, and placed in a treating tank as shown in Figures '7 and 8.

The corrugated structure of the liner cake B will permit the use of a thinner gauge of spring steel material, because by these corrugations the stiffness and tension of the metal sheet is greatly increased. It will be noted that the perforations l2 of the liner B are all in valleys so that the 'ribslB of the expander C will not block said perforations. 1

The tank, as shown in Figures 7 and 8 may be operated as described in my copending application, Serial No. 51,840 filed November 27, 1935 or as described in my Patents Nos. 1,706,826; 1,706,827; 1,988,364.

It is to be understood that the method and structure described above may be used for other purposes than for processing rayon cakes and in arrangements than shown in Figures 5 to 8.

In the tank shown in Figures 7 and 8, the heating coils 100 and I!!! may be employed for heating the liquid contents of the tank 50, which liquid contents may take the form of a dyeing solution or other suitable solution to be used for wet processing the textile materials A.

The

pipes

58 and 59 of the tank 50, as shown in Figure '7 may be connected to two expansion tanks as shown in my copending application, Serial No. 51,840 filed November 27, 1935 so that the treating fiuid may be caused to pass first radially outwardly through the materials A and then radially inwardly depending upon whether vacuum is being applied to the expansion tank connected to the pipe 58 or to the expansion tank connected to the pipe 59'. 0

Suitable drain connections may be provided or connected to the

pipes

58 and 59 to allow the treating liquids to be washed out of the tanks 5!) and discharged to a drain or to a sewer.

A drain line I02 provided with a valve I03 may be positioned at the bottom of the tank so as to enable hot air to be forced into the tank 58 to dry the textile material A or to enable the treating liquids to be drained.

To assure that the connection 5651 will be liquid tight, the hand wheel I04 may be connected to a threaded pusher member 155 which screws through a tap bore I05 in the boss ID! on the cover of the tank 5!.

The lower end of the rod N15 is provided with a contact member Hill which presses down on the ring and assures a tight connection between the nipple 56 and the recess or socket 51.

It is an important advantage of the present invention that all wet processing operations and the incidental drying operations may be carried out, once the rayon cakes have been loaded into the tank, as shown in Figures 7 and 8, and it is not necessary to remove these rayon cakes once they have been loaded until they have been completely processed and dried.

After the complete processing of the cakes, the cakes in the form of the units shown in Figure 2 may be shipped to weaving mills to be' put on creels for warping purposes or to winding mills to be wound into any shape required by the textile manufacturer.

The saving in operations by utilizing the process and apparatus of the present application results in a tremendous saving in cost and also assures the protection of a superior quality yarn, V

particularly in the case of fine denier yarns.

Any number of treating tanks, such as shown in Figures '7 and 8 may be connected to one central vacuum station such as shown in my above mentioned co-pending application, as for example, by switch pipe arrangement, to connect or disconnect at will. I

Many other embodiments might also have been shown and described and many changes and modifications might be made in the devices illustrated without departing from the scope and essence of the invention and it is intended to include all such altered or modified devices within the scope of the appended claims.
