METHOD AND APPARATUS FOR HANDLING TUBULAIR TEXTILE FABRIC Application am March 7-, 1929. Serial No. 345,180.

This invention relates to the handling of tubular textile fabric, either woven or knitted, and particularly to a method and apparatus whereby handling is facilitated and the quality and other characteristics of the fabric are improved. While it is adapted for use in the treatment of silk, cotton or wool fabrics in tubular form, the invention is especially applicable to the handling of knitted rayon,

10 the latter fabric being unusuall fragile when saturated with liquid and sub ect to shrinkage or deformation. 1

In handling fabrics after dyeing,- it has been the universal practice to treat the fabric in rope form or to spread it roughly by hand.

Thus it is usual to remove water in centrifugals and to dry the fabric without attempting to remove the wrinkles. The fabric is conveyed in a rough dry condition to the finishing machine where it is steamed and mangl to give it a commercial finish. The severa operations involve repeated handling of the goods in a wet or moist condition with the consequent possibility of defacing or distorting it.

dling of fabrics is the loss due to shrinkage which is especially marked in knitted rayon. The shrinkage loss in finishing is indefinite in amount, and no method of controlling it has been available. i 4

Shrinkage affects the width as well as the length of the goods. This is particularly true of tubular fabrics and is atthe same time especially objectionablebecause such fabrics are generally made into garments which, of course, cannot be properly out if the fabric does not conform to standards of width. Another difficulty in the handling of,fabrics arises from the fact that afterremoval of the major part of the water, they are frequently rolled or folded in a moist condition and held for periods of one to twenty-fourv hours before drying. This is necessary because drying is a slower operation than dehydration in. centrifugals and similar apparatus. When goods are stored in a moist condition, even temporarily, the edges or other exposed portions dry out and oxidation or other change may affect the dye at the exposed scribed have not been available.

An even more important factor in the hanportions of the fabric. The result is streaks or discoloration which cannot be removed.

Furthermore the ordinary treatment to which fabrics are subjected prior to finishing reduces the ultimate strength of the fibres of which they are composed. The uneven stresses to which the fabric is'subjected distort it and often cause serious defects therein.

The repeated handling increases the chances I of soiling and tearing the fabric. It involves also a very considerable'labor cost, much of which is unnecessary.

These and other disadvantages are the unavoidable result of a procedure which is ill adapted to the character of the material treated and which has survived because-the improved method and apparatus hereinafter do.-

It is the primary. object of the present invention to provide a; method and apparatus which avoid the difficulties and disadvantages of the procedure heretofore followed and especially to simplify and reduce the labor costsv incident to the treatment of fabrics, to overcome shrinkage both lateral and longitudinal, to strengthen the fabric, to

prevent soiling and deformation and to permit storage of the fabric in a moist condition without danger of discoloration owing to premature drying of the exposed edges. 7

It is characteristic of most fibres that shrinkage of fabric made therefrom occurs when the fabric is dried after saturation with water. For the purpose of the present invention the fabric is regarded as wet or saturated if it contains approximately 25% or more by weight of water based upon the dry weight of the fabric. The fibres are ductile,

and I. have discovered if the fabric is stretched while wet and subjected in that condition to heavy pressure the fibres are definitely elongated and permanently fixed so that if the fabric is again saturated and dried no substantial shrinkage occurs. It is possi- :ble consequently to secure higher yields in.

terms of yardage per pound of fibre used. Thus I am able to treat fabrics and-to deliver to the consumer a yardage greater than has been possible with methods heretofore in use.

The same advantage is obtained with-rebe stretched also in the transverse direction. The fabric may be given, therefore, a definite Width which will not be altered subsequently to any substantial extent even by repeated saturation and drying. The original sizes of garments made from the fabric will be retained, therefore, throughout the life of the fabric.

Since Wet fabrics and especially knitted rayon fabrics are extremely delicate, the stretching of the fabric and the tension to which it is subjec'tedfor that purpose must be carefully determined and controlled. The tension must be applied uniformly to all portions of the fabric. This is a matter of considerable difficulty in the case of tubular fabrics and consequently it has not been possible heretofore to subject fabrics of this class to uniform tension and stretching.

I have overcome the difiiculty by propelling the fabric by rolling contact with the major portion thereof so that the fabric advances evenly and without subjecting any part to stress which would tear or distort it. In fact, the movement is so uniform that the wales in knitted fabric are maintained parallel and straight.

This is accomplished by the application of a propeller hereinafter more fully described but embodying spaced rolls driven at a pre determined rate and cooperating with a floating stretcherframe enclosed within the tubular fabric and having rolls which are rotated by contact through the fabric with the spaced driven rolls. The tubular fabric is distended to the desired amount depending upon the initial and desired width by lateral adjustment of complementary parts of the frame. Rollers, which are positively driven to afford a peripheral speed preferably slightly higher than that of the spaced dxiv- 'ing rolls, co-operate with idler rolls outside the fabric at the lateral edges of the frame. Hence both the top and bottom as well as the sides of the tubular fabric advance at the predetermined rate. The fabric is initially opened by a spreader which is sized in accordance with the width of fabric treated and is interchangeable with spreaders of varying dimensions to co operate properly with the propeller. The spreader ofi'ers substantially no resistance to the fabric, friction being easily overcome by the uniform pull of the propeller.

The fabric thus fed or propelled at a uniform rate may be subjected to various opera-- tions, but in the present instance I am more particularly concerned with theremoval of most of the water. For this purpose I employ, preferably, wringer rolls having a hard surface. The hardness should be such as to prevent substantial deformation of the rolls under the pressure of heavy springs.

It has not been practicable heretofogre to employ hard rolls with heavy pressure inwringers employed in removing water from delicate fabrics because any wrinkle in the fabric, presenting a plurality of thicknesses, would cause the fabric to be out or weakened. Soft rolls, such as are customarily used in wringers, do not remove sufiicient water, hence the use of centrifugals.

If, however, the fabric is fed or propelled in a distended condition and under tension to the wringer, all wrinkles are avoided. The fabric is absolutely flat and can be subjected to any desired degree of pressure between the hard rolls. In fact, heavy pressure is desirable since it fixes or sets the fabric in its stretched condition and actually strengthens the fibres and the fabric. At the same time, the wringer removes a large proportion of the water and prevents the formation of moir effects and other discolorations which result from the uneven elimination of soapy water under the ordinary treatment heretofore employed.

To effect the stretching of the fabric in the direction of its length a suitable tension is maintained in-the fabric between the pro- ,peller and the wringer rollers. The tension is maintained by a difi'erential in speed of the fabric at the rolls of the propeller and wringer. This is efiected by driving the wringer rolls to give the fabric a definite linear speed at the bight of the rolls and by similarly driving the rolls of the propeller so that thefabric is fed at slightly lower speed. The tension must be varied depending upon the particular fabric which is treated and should be adjusted to give the required stretch to the fabric. Provision may be made, therefore, to vary the speed of the propeller rolls, forexample. Thus any desired diflerential may be maintained with a corresponding longitudinal tension on p cation of heavy pressure by the hard surface of the rolls. The fab-ric leaves the wringer as a flattened tube, flat and free from wrinkles and vquitedry. It may be folded or preferably rolled on a mandrel andthereafter sub-- jected to further treatment to dry and finish. the fabric, or it. may be delivered directly to the drying or finishing machine.

If the fabricis rolled or folded in a damp condition to. await further treatment, difficulty might resultfrom premature drying of the edges. This is avoided readily, however,

by slightl crowning one or both of the" wringer ro ls. Thus the'pre ssure on the fabric at the center isslightly greater than atthe edges and the pressure may be adjusted so as to leave at the edges a slight surplus of moisture. I Thus if the roll of fabric stands for a period of twenty-four hours oreven more the edges will remain sufliciently moist to prevent discoloration by premature drying. The amount of crowning necessary to accomplish my purpose is very slight and is plus water in the edges of the fabric prevents premature drying. Oxidation or stain ing is thus avoided.

It will be understood that the fabric in rope form from the dye vats or other treating apparatus can, in a single operation, be substantially freed from water, the water being removed so as to leave no marks or discolorations, smoothed and wound, if desired, on a mandrel which facilitates the subsequent handling. At the same time, the fabric is stretched both laterally and longitudinally. The fabric acquires a permanent set in the dimensions to which it-is stretched and those dimensions are not affected to any substantial degree by any subsequent treatment of the fabric.

While the invention as herein set forth is concerned primarily with the removal of water, the principles may beapplied to other;

.- operations. Thus the ropelleror a plurality of propellers may e employed to feed frames wherethe fabric over suitable drying h ot air or ot er on the fabric is subjected to drying medium. Similar the fabric may ropelled. and fed to eated rolls and. sub ected' intermediatel to steaming. The heated rolls iron and ni'sh the fabric. It ma be wound directly on a mandrel.

hrou bout the treatment of thefabric after it eavesthe wringer rolls it maybe .wound in rolls so that only. the edges and outsidelayer are exposed; These nay be protected easily and since there is no'necessity for the operator to touch the fabric, the possibility of soiling itis nullified.

The procedure in fact affords a markedsaving in material and in-labor and assures the production of a product of the highest quality at the minimum cost.- The saving accomplished by stretching the fabric is particularly marked and when considered in re lation to the high value of the fabric and the enormous ardage, produced this advantage alone is su cient to ensure the replacement of methods heretofore in use.

The method of this invention is not restricted to any particular apparatus. Nevertheless I have illustrated in the accompanying drawing an embodiment of the invention in a machine which is adapted to accomplish the various objects.

roller.

Referring to the drawing, the machine rests on a base 1. It includes a frame-consisting of

supports

2 and 3 which are connected by 's a sectional view of the wind-up beams 4. Brackets 5 are supported on the frame and a roller 6 is journalled in the brackets and serves as a support for the spreadingbar hereinafter described. A ring 7 on a bracket 8 guides the material. into the machine. A- pair of rollers 9 in parallel spaced relation are supportedby shafts 10 which are journalled in the frame. These rollers co-operate with the propeller as hereinafter described.

The machineis driven through a belt 11 or other suitable driving connection from any source of, power. The belt engages a pulley 12 on a shaft 13 carrying a sprocket 14. A chain 15 connects the sprocket 14 'to a sprocket" i 16 on a shaft 17 journalled in the frame of the machine. A sprocket 18 on the shaft 17 is connected by a chain 19 to a sprocket 20 on a stub shaft 21. The latter shaft carries a gear 22 which meshes with a pinion 23 mounted on a stud 24' which is mpvable in a slot 25 of an arm 26 pivoted on the shaft 21. The arm 26 is provided with a handle 27 and is slotted at 28 to receive a'bolt 29 secured in the frame of the machine. Thus the arm may belocked in any desired position, and when released may be moved by the operator to disengage the pinion 23 from a gear 30 on the lower shaft 10. The shafts l0 carry meshing gears 31 so that they rotate in opposite directions at the same peripheral speed. The gear 30 is removable and a gear having a different number of teeth to which longitudinal bars 32 are secured,

these bars extending inwardly toward the central portion of the propellerwand overlapping so that the end bars or plates 32 may be moved toward and from each other to contract or expand the propeller. Two rollers 33 are mounted on each ofthe end plates .32 to drivethe tubular fabric which is distended over the propeller, and stripper bars 34 are provided at the ends of the propeller to avoid entangling the fabric in the mechanism.

Four transverse rollers. are supported in the propeller, the rollers being composed-respectively of sections 35and 36 having short shafts 37 journalled at their outer ends in the end plates 32. The innerends of the shafts 37 are journalled infplates 38. A rod 39 on one of the end plates 32 telescopes within a tube 40 on the other end plate and a compression springe4l surrounds the tube .and rod and tends to spread the end plates asindicated in Fig. 7. In Fig. 5, the prope'ller is illustrated in its contracted position corresponding to the smallest size of tubular fabric which may be treated in the machine. In this position the ends of the -several sections .35 and 36 of the transverse rollers are contiguous, and the bars 32' of the frame overlap to a considerable extent.

In Fig. 7 the propeller is expanded so that the

sections

35 and 36 of the several transverse rollers are spread apart with their opposed ends separated.

The end rollers 33 are connected to and adapted to be driven from the

sections

35 and 36 .of the transverse rollers through bevel gears 42 connecting the shafts of the several rollers. Thus when the transverse rollers are driven by co-operationwith the rollers Si -the end rollers 33 are likewise driven at a uniform and predeterminedperipheral speed to propel the fabric without distorting or subjecting it to uneven strains. It is desirable that the peripheral speed of the end rollers 33 slightly exceed that of the transverse rollers, and the gear ratio may be such as to effect this result. Lagging and possible distortion of the fabricat the edges isthus avoided.

The fabric 43 as it appr oaches the propeller passes over a wire frame 44 which opens the fabric initially. The wire frame 44 is bent to a U-shape and the ends are turned and inserted in apertures in a cross bar 45. This cross bar is provided with circumferential grooves 46. The bar 45 is adapted to be inserted in sockets 47 of brackets 48 which engage the circumferential grooves 46. The bar 45 holds the frame 44 in proper alignment with the

sections

35 and 36 of the transverse rollers. If .the fabric is to be expanded to a 20" width for example, the spread of the wire frame will correspond to this width and the grooves 46 in the bar 45 will be so positioned that when they are engaged in the brackets 48 the frame of the propeller. will be looked against expansion and contraction. The propeller will be adjusted then so as to distend the fabric to the desired extent, that is to say, so that the fabric when flattened will have a Widthof 20". If-a wider fabric is to be treated,' ;the wire frame is removed and another of proper size is substituted. The latter willhave grooves 46 adapted to lock the sections of the propeller in a new position which will ensure distension of the fabric' to the required size.

011 parallel rods 49 mounted between the frame members of-the machine I provide two traveling blocks 50 and 51 each with a central opening to receive a threaded shaft 52 which is 'journalled in the frame of the machine and is provided at one end with a hand wheel 53. This shaft is provided at one end with a right-hand thread 54 and at the other with a left-hand thread 55,- the openings in the respective blocks 50 and 51 having corresponding internal threads. Upwardly extending rods 56 on each of the blocks 50 and 51 carry idle rollers 57 which are adapted to press the fabric against the end rollers 33 of the propeller to ensure suflicient traction so that the sides of the fabric are propelled positively and uniformly and at a uniform speed with the remainder of the fabric. By operating the hand wheel 153-to peller. When the hand wheel is turned in the opposite direction, the blocks 50 and 51 are moved apart to separate them from the end rollers 33 so that the fabric may be placed about the propeller.

After passing over the propeller the fabric engages guide rollers 58 which are mounted on arms 59 attached by brackets 60 to the longitudinal bars 32 at the delivery end of the propeller. These guide rollers 58 hold the fabric distended in the form of a flattened tube and guide it in this condition up to a point close to the bight of the wringer rollers hereinafter described. The guide rollers 58 do not come into contact with the.

wringer rollers and do not, therefore, injure the fabric.

The wringer rollers 61 are supported in brackets 62 attached to the side frame of the machine. The upper roller is driven by the shaft 17, and gears 61 connect the rollers so that they are both positively driven. The

upper roller is adapted to be pressed. clownwardly by means of screws 63 which engage springs 64, the latter resting in the bearing blocks of the upper wringer rollers. Thus the pressure of the wringer rollers may be adjusted by turning hand wheels 65 on the screws 63. The springs are sufiiciently heavy to exert a considerable pressure uponthe fabric as it passes through the wringer rolls to ensure the maximum removal of water from the fabric. 1 I prefer to employ a springpressure of from 1000 to 3000 pounds at each hearing.

The wringer rollers may be made of any suitable material, but for the purpose of the present invention I prefer to-employ hard rubber, that is to say rubber vulcanized to the point at which it will exert a substantially non-yielding pressure. 'Rubber having a hardness indicated by a durometer reading of from 90 to 100, preferably 98 or 99, is

best adapted to accomplish the object of the invention. Such rollers are contrasted with the ordinary soft rubber rollers which are employed ordinarily in wringers. They are adapted toapply high pressure to the fabric under the influence of the heavy springs-64 and thus to remove the maximum amountof IDOiStllI'G from the fabric; As hereinbefore' are made slightly larger at the middle portions and are tapered at each end so that when these rollers are in contact witheach otherthey touch at their middle portions and are in very slight contact or slightly the middle. I

spaced at the ends. The amount of crowning may bevery slight, that is to saythe diameter of the ends may be only a few thousandths of an inch less than the diameter of I refer to crown both rollers, but the object o the invention can be attained by employing one crowned roller co-operating with a cylindrical roller. In Fig. 11 of .the drawing the crowning is greatly exaggerends will not dry quickly and consequently there will be no discoloration of the fabric at the exposed edges.

In the apparatus as so far described, the fabric 43 is distended over the propeller, is propelled thereby toward the wringer rollers, and is engaged by the wringer rollers and subjected to pressure for the purpose of removing water. erally and is maintained in a stretched condition by the rollers 58 until it enters the bight of the wringerrollers. An important feature of the invention is that the fabric is subjected to longitudinal as, well as lateral tension between the propeller and the wringer rollers. It is engaged positively by both the propeller and the wringer rollers and cannot slip. Consequently it is possible to malntain a definite tension on the fabric and thus to stretch it to thedesired extent.

The fabric is stretched-lat- The stretching is accomplished by 'differential linear speed of the fabric at the propeller and at the wringer rollers. This differential is maintained by synchronizing the peripheral speed of the rollers of the propeller and wringer. Thus, for example,

if the propeller is set to ropel the fabric ata linear speed of 29 yar s per minute and the wringer rollers are set to propel the fabrid at a linear speed of 0 yards per minute, the fabric will be stretched accord- .ingly and uniformly while, it is in a wet or saturated condition. It will also be held distended to a uniform width until the moisture is extracted'by the wringer rollers.

The pressure exerted upon the fabric between the wringer rollers to extract a large percentage of t e moisture while the fabric is under tension fixes orsets the position will be permanent, that is to say, after the treatment, whenever;the fabric is free the 'of each stitch in the fabric, and this position regulating the tension on the fabric while it is in the moistened condition and by extracting the moisture while it is still held under lateral and longitudinal tension it is possible to set the tension between the several stitches so that the tube when it emerges from the machine will have a greater or less yield as desired, that is to say, a definite number of yards per pound within certain physical limits of the fabric.

The stretching effected between the spreading device and the wringer rollers is possible because of the physical property inherent in every fibre to a greater or less degree called ductility. Tension between the propeller and the wringer rollers results in elognation of the fibres. The fabric stretched and elongated while wet passes into the wringer rollers. Because of the flat and attenuated condition of the fabric, the great pressure exerted by the hard rollers, and the simultaneous removal of the greater part of the water, the condition of the fibres composing the fabric is set and the fibres remain in their new and extended relation throughout all subsequent treatment of the fabric.

' The result is that shrinkage is decreased to a minimum. The elasticity of the fibre is reduced because of the elongation, and the ability of the fibre to return to its original normal length is decreased to an extent which substantially aviods subsequent shrinkage.

The elongation effected is variable and can be induced to a greater or less degree, depending upon the type of fibre and the amount of stretching desired. This permits control of,

' yield Yield means that for a definite width of a given cloth there is a given number of yards per pound. In the method described the yield can be materially increased and it can be controlled so that a definite ratio of yardage, width and weight is possi 1e.

It will be understood that in the practice of the invention the amount of stretch to which the fabric is subjected .will be varied depending upon the particular characteristics of the fabric. Consequently the peripheral speed of the propeller rolls will be adjusted so as to feed the fabric at the required rate, that is to say at a. linear speed proportionally lower than the linear speed of the fabric at the wringer rolls, thus providing the necessarydifierential in speed to effect and maintain uniform stretching. When onceadjusted for a fabric of given character,

no further change need be made. In passing through the machine every inch of the fabric is subjected to the uniform lateral and longitudinal stretching to accomplish thepurpose described.

As an example of the application of the invention, a tubular rayon fabric was treated in the ordinary manner, i. e., the water was removed in a centrifugal and'the fabric was I I l 1 dried. It measured 62 yards. This fabric was again saturated and passed through wringer rollers under tension as hereinbefore described. The fabric was then dried and measured 66 yards. The fabric was again saturated and treated in the usual manner in 'a centrifugal and then "dried. It still measured 66 yards, showingthat the gain in yardage was permanent.

Another advantage of the invention is that the stretching of the fibres actually increases the tensile strength thereof. Elasticity is reduced, but the fibres are stronger and the fabric is correspondingly less liable to damage through the breaking or tearing of the threads. This is of special importance in connection with rayon fabrics because of the natural weakness of rayon fibre.

In the operation of the apparatus it is desirable to facilitate theintroduction of the fabric. Consequently I provide means for feeding the fabric from the propeller to the wringer rollers when the operation is initiated. F or this purpose vertical supports 66 are disposed above the propeller and are provided with connecting blocks 67 at the top of which the feeding device is pivoted. The

feeding device may consist of a shaft 68 journalled in extensions of the blocks 67.

provided with a narrow blade 72' with a serrated edge73.

The shaft 68, together with the arms 69, is adapted to rock, and I have provided means which normally tend to move the arms 09 toward the wringer rollers. In the particular deviceillustrated, there is an arm 74 fixed to the shaft 68 and provided with a weight 75 which is on one side of the axis of the shaft, so that this weight tends to .revolve the shaft 68 in a direction to cause the arms 69 to swing into the position shown in Fig. 13. A clip 76 on one of the arms 69 is adapted to engage a sleeve 77 on the upper shaft 10 (Fig. 12) to hold the arms 69 in retracted position. The fabric is threaded over the propeller, and the ends are slipped over the blades 72 and are caught on the serrated edges 73. The machine is then started. Rotation of the shaft 10 disengages the clip 76 and permits the arms to advance with the fabric under the influence of the ,operative position before the arms 69 advance and is then moved intoposition by the operator to engage and hold the arms 69 in retracted position until a new piece of fabric is introduced to the machine- The arms are then retracted'to engage the clip 76 with the sleeve 77 and the feeding operation is repeated.

- It is also desirable to facilitate the wind-,

ing of the fabric as it comes from the wringer rollers. For that purpose an endless belt 78 travels around pulleys 79 and 80, the upper run of this belt bein positioned to receive the fabric as it leaves the wringer rollers and to convey it to the winding roller. The pulley 79 is driven through a sprocket 7 9" and chain 81 from a sprocket 82 on the shaft 17. A roller 83 is provided with trunnions 84 which are adapted to engage the inclined surface of supports 85- When this roller is in its lowest position it rests against the belt 78 adjacent the rear pulley and as the fabric is wound on the roller 83 the trunnions 84: rise up along theinclined surface of the supports 85. The roller 83 is provided with means for automatically engaging the leading edge of the fabric to carry it around the roller. In the present embodiment the roller is provided with grooves 86in which a are mounted circumferential strips 87 of cloth upon itself in the form of a roll.

provided with closely arranged pins 88 proj ecting outwardly therefrom. a The ends of the pins 88 project slightly beyond the pe riphery of the roller 83 as shown in Fig. 17.

As the leading edge of the fabric leaves the wringer rollers it is guided by a lip 80' on to the belt 78 and the latter carries it along'untilthe end is touched by the {revolving winding roller 83, this roller being revolved by the belt 78 with which it contacts. The several pins 88 will engage the 6nd ofthe fabric and cause the latter to be picked up automatically so that it travels around the roller and is wound Thus it is unnecessary for an attendant to stand at'the delivery end of the machine and start the end of each strip of the fabric on the winding roller.

, The mechanism also avoids the folding of the fabric at the starting end and saves .a portion of the fabric which is ordinarily rendered unsuitablefor commercial use.

In the operation of the machine as described the operator first adjusts the propeller to distend the fabric to the required degree by introducing a stretching frame of the required The end of the fabric is then is automatically wound on the roller 83.

' 'J- slipped over the stretching frame and propeller. The side edges of the fabric are drawn forwardly and pass over the forward edges of the blades 72. The swinging arms 69 will be in the position shown in Fig. 1 and will be held temporarily in this position by engagement of the clip,76 to overcome the tendency of the weight 75 to move the arms 69. The power is then applied and the propeller commences to operate and propel the fabric. Simultaneously theleading edge of.

the fabric will be drawn by the arms 69 at a speed corresponding to that of the propeller. The flattened tube will pass over the guide rollers 58 and will be fed then into the bight of the wringer rollers. The rollers 57 are then moved to engage the fabric. The

wringer rollers will propel the fabric and the feeding device, having performed its function, is retracted. and will. remain inactive until another strip of fabric is threaded through the machine. It will be observed that the blades 72 may pivot to a slight extent so that the sharp blades may project accurately into the bight of the wringer rollers.

As the fabric is propelled between the wringer rollers itpasses onto the belt 78, and when the leading end reaches the roller 83 it is engaged thereby and is carried around the roller. Thereafter the fabric is wound in the form of a roll.

The fabric is first opened by the frame 44 preparatory to its assage over the propeller. From there the fa ric travels over the ropeller whichholds it distended or stretc ed, and at the same time it ispropelled-by rolling contact exerted both inside and outside the tubular fabric. The fabric then passes beof the spreading guide rollers 58. As the fabric passes from the wringer rollers, travels with the upper run of the belt 78 and The method and apparatus herein described are applicable to the treatment of fabrics in tubular form. These may .be knitted or woven' fabrics. Woven fabrics are not generally tubular as they come from the looms, but suc fabrics may be stitched in'tubular form for 5 treatment as described. After the fabrics are finished the stitching can be removed. The

benefits of the invention are thus'easily ,se-

cured, regardless: of the form-in which the goods are originally fabricated.
