The stream of one of the machines having rolls as the elefluid possesses a large amount of kin ti a so ments which create the fluid stream. ergy and if it is thus directed against the ten.- ce

the container tile, the speed of the stream will be decreased where itstrikes the textile, but a fluid pressure will be created which will cause the fluid to penetrate or pass entirely through the textile. To obtain this result in my machine each of the active rolls is surrounded by a hous ing which, for purposes of description, may be considered to include the inner wall 14 of and the baflle 15. During the usual operation of the machine the container is filled with fluid of such a level that all of the housings are filled and as the roll revolves it creates the stream of fluid just mentioned. The surface 16 of the bafile which is next to the roll is curved concentrically with the surface of the roll and the baflie is so placed in the machine with relation to the roll that there is an exceedingly small space between the face 16 of the bafile and the periphery of the roll. The face 17 of the baflie joins the face 16 in a sharp knife-like edge, extending across the width of the roll and container, which deflects the stream of fluid from its normal path of revolution. As is. shown the face 17 of the baflle is spaced from the opposite portion 18 of the inner wall of the container to form an outlet 19 from the housing as well as a passage to direct the fluid stream. The fluid in this passage is under considerable pressure due to the fact that the roll is continually revolving and tending to drive fluid into the passage and this pressure causes the fluid to penetrate the textile. If the pressure is great enough, as it usually is in the commercial operation of the machine, the fluid will pass entirely through the textile. Preferably, the rolls are driven at such a rate of speed that such a pressure is created at the outlet 19 as to force the fluid through the textile quite rapidly and with such force so that the fluid not only contacts with the individual fibers of the textile but is driven into the fibers with the result that a uniform treatment of the textile with the fluid may be obtained.

The inner wall of the housing is preferably given the contour shown on the drawings to assist in the eflicient functioning of the machine. For this purpose the wall of the hOlIS'. ing is flared so as to be a considerable distance from the periphery of the roll at ap-- proximately the 'point20 and approaches the roll in a smooth curve to a point 21 where the wall of the container is so close to the surface of the roll so that there is no opportunity for the fluid to form a back current along the housing, that is, at the point 21 the wall of the housing and the surface of the roll are so close together that the fluid stream created by the roll takes up all of the space between the surface of the roll and the wall. The distance between the surface of the roll and the wall of the housing at the point 21 is great enough however, to permit the passage of a fluid stream having sulficient volume to provide 7 narrow enough fluid to maintain at'all times a fluid pressure at the opening 19 and allow for the escape of so much fluid as willpass between the surface of the roll and the curved surface 16 of the baflle.

The fluid enters the housingthrough the large opening 22 formed by the end 23 of the housing and the'curved side 24' of the baflie. As is shown; the textile passes across this opening and the fluid enters the housing b passin through the textile. It will readily be understood that when the roll revolves and drives the fluid toward the opening 19 a suction will be created at the opening 22 which draws the fluid through the textile and the opening 22 is'lar e so that the textile is exposed to the suction For quite an appreciable time. This suction is increased by the action of the film of fluid which escapes from the pressure side of the roll through the curved surface 16 of the balfle- As the surface of the roll moves from under the end 25 of the bafiie, this film of fluid will assist in driving 1 the fluid. entering the housing through the opening 22 toward the more art of the space between the'surface oft e roll and the wall of the housing. From this explanation/ it will be seen that a single roll creates both a fluid pressure and a suction at spaced points on the same side of the textile and that the suction is created both by the action of the roll in creating the fluid stream which is driven against the textile on the pressure side of the roll and by the action of the film of fluid which escadpes from the pressure side to the suction si e of the roll between the surface of the roll and the curved surface 16 of thebaflie. By changing the size and shape of the baflie and the size and speed of the roll almost any correlation of pressure and suction may be obtained. It is obvious that the slower the peripheral speed of the roll, provided rolls of the same smoothness. of surface are used, the less will be the speed and kinetic energy of the fluid stream created and also the greater the space between the surface of the roll and the surface 16 of the baflie the more will be the fluid which escapes from the pressure side of the roll and consequently the less will be the pressure at the opening 19 and the reater will be the suction created by the lm of fluid which escapes from the pressure side of the roll into the opening 24 of the housing.

Although the machine-may contain only one active roll a plurality of rolls are preferabl used and the rolls and housings are prefera ly so spaced that the area of suction created by one roll isopposite, although not necessarily coextensive with, the area. of pressure created by another roll on the 0p posite side of the textile so that each roll cal,

passing through the textile. Thus, adjacent rolls on opposite sides of the textile may be considered as workingin airs and the roll 7 may be paired either with roll 4 or with roll 5. In the normal operation of the machine the roll 5 creates a fluid stream exerting pressure on one-side of the textile in the opening26 which pressure forces the fluid through the textile and at the same time the roll 7 creates a fluid stream exerting suction on the opposite side of the textile which tends to suck the fluid through the textile and in this way the rolls of-any pair cooperate in creating a stream of fluidpassing through the textile. Similarly the roll 7 creates a pressure at the opening 19 and the roll 4 creates a suction on the opposite side of thetextile so that the fluid which enters the housing through the opening 22 is forced from the housing through the textile and into the housing surrounding the roll .4. Considering all of the active rolls it will be seen that a continuous stream of fluid .passes back and forth through the textile first from one side of the textile and then from the other while the textile is continuously passed across the stream and between each passage through the textile energy is imparted to the stream. The baflles 15 acting conjointly with the wall 14 of the container surrounding the respective rolls separate the inlet and outlet openings into the housing and space the/points at which the stream passes back and forth through the textile and also limit the area of application of the suction and pressure created by the rolls. The stream starts with rolls 9 and passes through the textile into the suction side of the housing surrounding roll 6' which roll then imparts energy to the fluid stream and drives it through the textile into the housing surrounding roll 8 which roll in its turn imparts energy to the fluid stream and drives it into the housing surrounding the roll 5 and so on; Thus each roll is revolved at such a rate of speed and in such a direction with relation to the rolls of its set and-the rolls of the other set that a fluid pressure is created on one side of the textile and a suction is created on the opposite side of the textile so that a stream of fluid is created and forced through the textile. In a machine of the construction shown in Fig. 1 in which the rolls revolve in the directions indicated by the arrows on them the fluid stream continually moves from one end of the container toward the other end and in order to ,permit the fluid to return so that it may again pass through the textile the cover of the machine is provided with a passage 27 to provide for the back flow of the fluid. It is possible, although not economito prevent the rotation of any one or more of the active rolls or remove any of the rolls from its housing. The remaining rolls the baflies and the faces textile throug usually will then create the stream of fluid and drive it as previously described.

The textile which is fed to the machine is preferably of such a thickness that it, and its supporting aprons when such aprons are used, freely move through the space 28 provided for them as shown onthe drawings. To provide for the easy passage of the textile and aprons throughthe machine frictionless rollers 29 may be placed on the faces 30 of 31 of the wall of the container. The rollers also prevent the leakage of the fluid parallel to the textile or through the textile in the direction of its length from the ressure side of any roll to the suction side y pressing the.aprons 11' and 12 toward each other and compressing the textile and by filling the space between the aprons and the faces 30 and31 of the 'bafiies and container walls. Ithas been found that rollers situated on the housing in the positions shown in the drawings are sufficient to prevent the escape of fluid parallel to the textile and are also sufficient to provide for the easy movement of the textile and aprons through the machine, but more rollers may be provided at suitable points if desired. Different sized rollers 29 may be used to accommodate textiles of difierent thicknesses. Thus if a thin textile is run through the machine larger rollers 29 are used to compress the textile and prevent the escape of fluid from any pressure area to any suction area in a direction parallel with the textile or through the textile in the direction of its length. If the combined thickness of the textile and aprons .is such that, in their expanded condition after passing between the rollers 29, they fully occupy the space A over the feed roll 33 where it also meets the textile and together the aprons carry the the machine. The textile and aprons are drawn through the machine by means of the press rolls 34 and 35 which not only draw the textile through the machine, but squeeze the surplus fluid from the textile. The roll 35 draws the apron I2'away from the textile and returns the apron to the feed roll 33. The roll34 returns the apron 11 to the feed roll 32 by means of the idling rolls, 36 and 37. The treated lapped material may be removed from the apron 11 at any convenient point but is removed from the apron at the roll 34 as 18 illustrated on the drawings.

The parts of the machine are preferably so arranged that the textile passes through the machine in a plane, that is, the textile is kept perfectly flat when it is under treatment and does not pass around the active rolls.

his is especially/desirable in casethe textile is unwoven and has to be carried through the machine b the aprons. The plane in which the textile passes through the machine is parallel to the plane determined by-the axes of the active rolls of a set so that the textile is equally spaced at all points from any roll adjacent which it passes withthe result that the fluid stream is forced against the textilewith equal pressure at all points. For this purpose the-faces 29 of the baflles and the faces 30 of the wall of the container which form the space or passage 28 are flat and parallel to each other. These faces 29 and 30 of the baflle and container also have a considerable area so that, in addition to preventing the leakage of the fluid from the pressure side of a roll to the suction side the sur faces may support the textile as it passes through the machine. The baflles and bone ing for the active rolls are also preferably so placed with relation to the passage 28 for the textile that the fluid is driven perpendicularly against the textile which is desirable because it puts no strain on the textile along its length. The textile is guided into the passage by means of the guide rolls 38 and 39 which are preferably mounted in frictionless bearings so that they turn very easily. The guide roll 38 is of such a size and so placed that it takes the textlle directly from the feed rolls 31 and 32 and leads it directly into the passage 28 through which it passes through the machine. The guide roll 39 is of such a size and so placed that it takes the textile from the passage 28 through whloh itis passed through the machine and feeds it to the press roll 34.

The lower press roll 34 is driven from an electric motor 40 which drives a gear 41 which meshes with a gear 42 on the rose roll 34. The upper press roll 35 may, i desired,

be driven by the gears 43, 44 and 45. Gear 43 meshes with gear 42 and also with gear 44 which in turn meshes with the gear 45 on the upper press roll so that the upper press roll is driven in the correct direction to draw the textile through the'machine. Press roll 35 may, if desired, be driven by the gears 43, 44 and 45.

Fresh fluid is fed into the container to compensate for thatabsorbed by the textile. This fluid is contained in a tank 46 from which it is drawn by the pump 47 and forced by means of pipes 48, 49 and 50 into the container. The pipes 49 and 50 deliver the fresh fluid into pipes 51 and 52 which extend entirely across the machine and have small openings so that the fresh fluid is distributed entirely across the Width of the container.

Valves 53 permit the fresh fluid, to be de livered either at the end where textile ,rolls 7, 8 and '71 which are shown on Fig. 3.

that the active rolls are not the same entersthe container or at the end where thev textile leaves the container or both, as desired. The pump 47 is driven by means of a. belt 54 from the motor 40. The belt 54 drives a. pulley 55 to which the plunger ofv the pump is connected by the crank 56. By means of an adjustable connection,.such as the bolt and nut 57, between the crank and the pulley the stroke of the pump may be varied to supply a greater or less amount of fluid. The arrangement for varying the amount of fresh fluid supplied to the container is desirable becaues a thick textile removes more fluid from the machine than. does a. thin textile and therefore more fluid must be delivered .to the machine when a thick textile is treated than when a thin texti e is treated. The fluid which is squeezed from the textile by the press rolls 34 and 35 drips from the lower press roll 34 and is caught in a receiver 58 from allowed to return to the machine.

Steam or cold water ,may be admitted to, or withdrawn from, the spaces 59 surrounding the active rolls to control the temperature of the fluid and inlets and outlets 60 are provided for this purpose. The fluid with which the textile is treated/may be withdrawn from the container by the outlets 61.

Each set of active rolls may be driven as a unit from caring in a gear box 62 shown on Fig. 3. "fhe set of rolls 4, 5 and 6 may be driven from shaft 63 on which are mounted bevelled gears 64. A shaft similar to shaft 63 drives bevelled gears whichrevolve the 9. The bevelled gears 64 and 65 mesh with inions 66 which turn short shafts 67 whic through quick detachable universal joints contained in casings 68, drive the shafts 69 which are connected to the spindles 70 of the active rolls. The spindles for the rolls revolve in frictionless bearings Plates 72 on the side of the container and packing nuts 73 prevent the leakage offluid from the container and allow the active rolls to be removed.

Bearings 74 support the spindles 75 of the feed and press rolls and permit the rotation of these rolls. Bearings in housings 76 sup- "port the spindle of the guide roll 38 and permin the rotation-of the roll.

Bearings and housings similar to the bearings and housings 76 support and permit the rotation of the guide roll 39ibut these have not been shown on Big. 3 in order to simplify the drawing.

The machine shown in Fig. 2 is similarto the machine shown in Figs l and 3, except smooth but contain vanes 7'57. It has been found that by using rolls which have vanes a greater fluid pressure and suction 18 obtained by can be obtainedv than the use of smooth rolls having which it may either be drawn off or ateral speed, because the fill the space between are in effect a'roughening of the surface of the rolls and cause a greater friction between the rolls and the fluid so that the fluid stream formed by the revolution of the va-ned rolls has more kinetic energy than has the fluid stream created by the smooth rolls provided the smooth rolls and the vaned rolls are .re volved at the same speed. It is therefore poss'ble to revolve the vaned rolls at a slower speed to obtain a fluid pressure or suction equal to that set up by the smooth rolls. In the case of the vaned rolls the vanes may be of such a length that they do not completely fill the space between the base surface 7 f the roll and the wall of the container and they just clear the face 16" of the baflie. Therefore, as. the vaned rolls revolve they create the fluid stream which is deflected by the face 17 of the battle and passes through the textile as described above with regard to the smooth rolls.

The vanes may have any suitableshape or length. Fig. 5 shows a roll having vanes which are quite like the teeth on gear Wheels and gears have been successfully used as active rolls on machines for treating narrow strips of cloth. The roll shown in Fig. 6 has longer vanes than the rolls shown in Fig. 2 and if such a roll were used in the machine shown in Fig. 2 the vanes would completely the base surface 78 of the roll and the housing in which case it would be necessary to cut back the face 16 of the battle to permit the longer vanes to ass.

p The machine diagrammatically illustrated in Fig. 4; operates on the same principle as that shown in Fig. 1, but baflles'are not used. In this case the adjacent rolls of a set cooperate so that together they form either a fluid pressure or suction on the textile. For purposes of reference the rolls in this type of machine are numbered 79, 80,81, 82, 83 and 84: of which rolls 79, 80 and 81 compose one set and rolls 82, 83 and 84 compose the other set. Considering the adjacent rolls 82 and 83 of one set, it will be seen that these rolls revolve .in opposite directions so that their surfaces at the points 85 are moving in the same direction, that is upwardly, ates a fluid stream and draws the fluid with it the streams created by the respective rolls will join and create a fluid pressure on the under side of the textile which will force the fluid through the textile. The rolls 82 and 83 are preferably of such a size and so placed that the distance between the surfaces at the point 85 is less than twice the distance between the surface of either roll and the container at the point 86 so that the volume of the combined fluid streams set up by the rolls 82 and 83 will be more than suflicient to form a fluid stream filling the space and moving between the rolls at the point 85. Therefore,

as the two fluid streams 30in and move he andas each roll cre- I suction on one The stream of fluid which passes between the rolls at the point 85 possesses a great amount of kinetic energy an is driven with great force against the textile and has suflicient force to pass through the textile. The walls 88 of the container are preferably curved concentrically with the rolls and join'at the point 89 so that the fluid stream set up by each active roll is directed into the space between the rolls at the point 85 which also assists in maintaining the direction of movement of the fluid streams.

The rolls 79 and 80 are revolved in such a direction that they cooperate to create on the textile a suction opposite to the pressure created by the rolls 82 and 83. As the fluid passes from the space 87 through the textile the rolls 79 and 80 pick it up and drive it into the spaces 90 between the rolls and the wall 88 of the container. The rolls 79 and 80 are of such a size and so placed that the distance between the rolls at the point'91 is less than twice the distance between either roll and the wall 88 of the container and therefore all of the fluid which passesbetween the rolls at the point 91 may easily escape, that is, the combined volume of the passages between the rolls 79 and 80 and the wall of the container at the points 90 is greater than the volume between the rolls 79 and 80 at the point 91 andtherefore no up in the spaces 90 which will prevent the rolls from drawing out of the suction space 92 all of the fluid which passes through the textile. Thus considering the rolls.79 and 80 and 82 and 83, it will be seen that the two adjacent rolls of one set, for instance the rolls 82 and 83, revolve in opposite directions and cooperate to produce between them a,

stream of fluid exerting a fluid pressure .on

one side of the textile and also cooperate to form a fluid stream passing through the textile; and the rolls 7'9 and 80 also revolve in opposite directions andcooperate to form between them a stream of fluid exerting a side of the textile and to form a fluid stream passing through the textile each of the rolls being so revolved with re-' gard to speed of rotation an its position relative to the textile and to the adjacent roll that these results are obtained. When the rolls 79 and 80 revolve in opposite directions the adjacent surfaces of the rolls at point 91 move in the same direction to exert a suction on the textile and likewise when the rolls 82 and 83 revolve in opposite dire-a tions their adjacent surfaces at point- 85 move the stream at moving very swiftly and more,

space 87 next pressure is built in the same direction to exert a pressure on the textile. If the opposite rolls and 83 are considered as a pair it will be seen that these rolls revolve in the same direction and cooperate with each other to create aifluid stream passin through the textile, the roll 83 creating a fluid pressure over an area on one side of the textile and the roll 80 creating a suction on the other side of the textile. Therefore each roll is revolved at such a rate of speed and in such a direction with relation to the rolls of its set and the rolls of the other set that a fluid pressure is created on one sideof the textile and a suction is created on the opposite side of the textile so that a. stream of fluidis created and forced through the textile.

The active rolls 81 and 84 are preferably similar to the other active rolls and are so revolved that they cooperate with the rolls 80 and 83 in the same way as do the rolls 79 and 82. Thus the roll 81 coo erates with the adjacent roll 80 to form a uid pressure in the space 93 and the roll 84 cooperates with the adjacentroll 83 to create a suction in the space 94 and the adjacent rolls 81 and 84 cooperate with each other to form afluid stream passing through the textile. All of the rolls cooperate to create a fluid stream passing back and forth through the textile first from one side of the textile and then from the other while the textile is continuously passed across the stream and each roll imparts energy to the stream between each passage through the textile. The rolls space the oints at which the stream passes back and orth through the textile and limit the areas of application of the suction and pressure. a

The ends of the container adjacent the outside pairs of rolls are especially designed to assist in creating the fluid stream. For this purpose the wall 95 of the container is spaced a considerable distance from the roll 82 so that a reservoir of the fluid is provided in the space 96 and the wall of the container at the point 97 is substantially straight so that the stream of fluid created by the roll 84 is directed against the textile. The textile 10, which is Without the supporting a led between the sets of rol s in a plane parallel with the planes determined bythe axes of the active rolls of either set and perpendicular to the lane determined by the axes of the active rol s of any pair. Guide rolls 38 and 39 similar to those described in' connection with Fig. 1 are used for this purpose. These guide rolls are of such a size and so placed that the feed the textile between the active shown in Fig. 4

rolls an remove it therefrom as'is described in connection with Fig. 1. The textile is preferably of such a thickness'that it almost entirely fills the space between the active rolls of any pair of rolls and thus prevents the such as is sh rons, is preferably of. the fluid stream and escape of any large amount of fluid parallel with the textile. If the textile touches the rolls it is possible that the friction will heat the textile. In this type of machine however, it is preferable not to have the textile touch the rolls and therefore the textile passes between the opposite rolls in a plane substantially at right angles to the plane determined by the axes of the rolls so that the textile is adjacent the rolls for as short a distance as possible and the rolls are preferably revolved at such a rate of speed that they carry with them a film of fluid between the surface of the roll and the textile. Thus, the'textile rides over the rolls on a film of fluid. The speed at which the rolls must be revolved to maintain this film of fluid on the surface of the rolls depends upon the viscosity of the fluid and the permeability of the textile, as well as the thickness of the textile, but ordinarily any speed of revolution of therolls Which will create the fluid stream through the textile is suflicient to maintain the film of fluid between the surface of the roll and the textile. This fluid film which asses between the surface of the roll and t e textile leaves the surface of the roll in the suction space and assists in creating the suction as has previously been described in connection with Fi 1. Thus, the films of fluid between the sur ace of the roll 7 9 and the textile and between thesurface of the roll 80 and the textile are thrown away from the surface of the respective rolls as the surfaces move away from the textile, that is, the fluid of the films is thrown into the suction space 92, but as the fluid films are moving in the direction of revolution of the rolls they meet and assist in creating the suction in the space 92 and thus assist in drawing the fluid from the pressure space 87 into the suction space 92 and thus assist in creating the stream of fluid passing through the textile. Since the textile is not supported by bafllesin a machine own in Fig. 4, the textile will bulge slightly from the pressure space 87 toward t e suction space 92 and will also bulgefrom the pressure s ace 93 to the suction s ace 94, but this bulging may be prevente in large measure by keeping the textile taut While it is passing through the ma chine.

In the machine shown in Fig. 7 the movable elements are continuous belts 98 and 99 which move in contact wiii the fluid and create the fluid stream As in all of the machines shown, the stream of fluid is parallel to the surface of the moving element; in the case of the machines shown in Figs. 1, 2 and 4 the stream is concentric with the active rolls and in Fig. 7 the fluid stream is parallel to the surface of the belt. Baflles 100 are so placed in the machine that they lie in the path as the stream strikes the baflles a fluid pressure is created which erably of such a size that one-end of each baflle lies close to the moving belt and theother end of the baflle lies close to the textile and the faces of the'baflles are such that they perform their function of deflecting the fluid stream and directing it against the textile with as little reduction of the energy of the stream as is possible. Baffles substantially like those shown in Fig. 7 are deemed satisfactory. Such baflles lie entirely across the space between the textile and the adjacent belt and have curved forward faces 101 to deflect the fluid stream and direct it against the textile.

When the belts are moving .fast enough to give the fluid stream sufficient kinetic energy, the fluid will pass entirely through the textile and the baflles on opposite sides of the textile are preferably staggered so that one baflle directs the fluidstream through the textile in one direction and the next baflie causes the fluid stream to pass through the textile in'the other direction. is preferably so spaced from the adjacent baflle of its set on the same side of the textile that the fluid is exposed between the adj acent baflies to the action of the belt on that side of the textile for a sufficient length of time to impart suflicient energy'to the fluid to drive it through the textile when it strikes the next baflle. Therefore, in the case of the machine shown in Fig. 7, as in the cases of the machines shown in Figs. 1, 2 and 4 the fluid stream passes back and forth through the textile and energy is, imparted to the stream after each passage of the fluid through the textile. i

It will be understood that as either belt passes a baflie and the fluid stream is deflectedf'rom the surface of the belt by the a suction Wlll.

back of the forward face 101 of the bafile, be created in the space 102 in bafltle and this suction will assist in drawing the fluidthrough the textile. Thus each baflie acting conjointly with the adjacent belt creates both a fluid pressure and a suction on the textile, the pressure and suction being on the same side of the textile and at spaced points-and also adjacent baflies on opposite sides of the textile simultaneously create a suction-and a pressure on opposite sides of the textile.

Any number of baflies may be used but pref erably only enough are used and they are sospaced that the pressure and suction areas eflecti've creation are arranged for the most back and of the fluid stream and its passage forth through the textile. i

The belts 98 and 99 are movedby means of the pulleys 103 which may be driven in any suitable manner as, for instance, by a will have to be Each baflle same reason the sides 106 modified gear box similar to that shown in Fig. 3. Also the belts may be moved ineither direction but they are preferably moved in the same direction and opposite to the movement of the textile as shown in Fig.7. When the belts are moved in the direction shown, the fluid will move from right to left with the belts along the center line of the machine and will move from left to right with the belts along the top and bottom of the machi-nean d in this way a circulation of the fluid will be obtained. The speedof the belts depends upon such factors as the thickness of the textile, the viscosity of the fluid, etc. Obviously the thinner the textile the easier the fluid will pass through it and the less the speed of the belts.

The space between the upper and lower parts of eagh belt is filled in by the casings 104 so that the amount of space in the machine which the fluid may occupy is decreased to the end that as little fluid as possible need be usedin the machine. Steam or cold water for heating or, cooling the fluid may be admitted into or withdrawn from the interior of the'casing through the openings 60 and the fluid may be withdrawn from the cons tainer through the pipe 61. The ends 105 of the casings are preferably curved concentrically with the pulleys 103 and lie very close to the surface of the pulleys so that little or no fluid is between the ends 105 and the pulleys because it is not desired to form a fluid stream in this space, the formation of which would consume energy. For the of the casing lie the belts and the sides also serve closely to 4 the belt where the belt passes next to back up to a baflle.

The textile is fed into the machine 11 means of the feed rolls 32 and 33 and is withdrawn from the machine by means of the press rolls 34 and 35. The guide rolls 38 and 39 are so placed that they take thetextile from the feed rolls and deliver it to the press rolls and maintain the textile while it is passing through the machine in a plane mid-way between the belts 98'and 99.
