the; embodiment of; the invention as here shown the sizing machine or slasher section 15011 slashing the warp yarns i-s organized as follows: Suitable end-frames orstandards 2 support a size-vat 3 constructedin the form of a tank or trough. The size vat 3 hasend members 4 provided with bearings for the end journals of two shafts 5 and '6 which carry the coppersize-rolls 7 and Sextending horizontally across the size-vat to adapt theml to partially immersed in the starch or sizing-fluid S contained therein. At one endv 01; the shafts 5" and 6' are meshing with a driving-gear ll journaled on the end-member 4. The drivinggear 11 carries a bevel-gear12=on its side from which it is driven through'the means of: a bevel.- pinion 15 fast on a shaft 1-6. The shaft 16 is journaled in a bearingll'fl attachedtothe side of" the end-frame or standardQ, and

gears 9 and 10 I extends to the right of the machine to adapt 7 it to, be connected with any Of power. Usually the shat-t 16 is connected to, the winding-drum on the drying end of the slasher, not hereinshown, to be driven fromv the power mechanism thereof:

suitable source At the. receiving end of the machine are 7 suitable guiderollers l9and across which the warpfyarns' to lead. as they feed-into the size-vat 3 from the section-beams, not herein shQwn. The

rollers

19 and 20 have'trun-n nions 21 and 22 journaled in suitable bearings at the top ofthe end-members 4 of the vat. Within the vat 3 is animmersion-roll 23 having its end-gudgeons 24 supported from pendant in Fig. 1. The arms 25 are connected at their upper ends tolvertical-racks 26 arranged at eitherend ofthe vat on the outside not the. end-members tp The racks 26 are adapted toeslideup and down to raise and lower the immersion-roll 23 in the vat m regulateits degreeofi submergence in the ingwfiuid S in accordance with the level thereof. The racks-26 are operated from DQ119115 2-? at the ends of" shafts 28' which are journaled in bearings 29 on the standards z." The Shafts 2S carry w o-rnrgears meshing with worms 31 on a horizontal cross shaft On the end'of the shaft 32' is hand-wheel 33 by means of which it may be manually rotated to. turn the shafts 2810 raise and lovYenthe. racks. 26' in accordance with the usuaharrangement arms 25 shown by dotted lines from the section-beams, not herein shown, across the guide-

rolls

19 and 20, thence down under the immersion-roll 23 and up over the size-rolls 7 and 8, whence they lead to the drying section of the machine. Above the size-rolls 7 and 8 are the squeeze-rolls and 36 arranged with their peripheries hearing against the size-rolls. The squeeze-rolls and 36 have journals 3'? and 38 constituted by reduced portions of their axial shaft-s 39 and 40, see also Fig. 2. The journals 37 and 38 are received in

slotted bearings

41 and 42 formed as a part of and projecting upwardly from the end-members 4 of the size-vat 3.

In my new and improved construction of the squeeze-rolls I provide the barrels of the rolls with end-flanges or

heads

43 and 44 which overlap the ends of the lower sizerolls or drums 7 and 8. These flanges may be of relatively thin metal, preferably brass, and are employed to sustain and hold in place the roll-covering which is applied to the peripheral surface of the squeeze-rolls. I also provide the squeezerolls and 36 with spurgears 45 and 46 mounted fast on their shafts 39 and at the side of their end-flanges. The gears and 46 serve as means for connecting the squeezea'olls to drive the mechanism which applies the outer surface-covering to the barrels of the rolls.

As shown more particularly in Figs. 2 and 3, the present improved mechanism for applying the covering to the squeeze-rolls comprises means for winding onto the barrel of the rolls one or more layers of strands of textile material such as cotton or worsted yarns. Preferably, I employ cotton yarn for the covering of the first roll yarn for the finishing-roll 36, but it is to be understood that the character of the covering material may be varied in accordance with conditions and the results desired. In accordance with the preferred practice, the barrels of the squeeze-rolls are first covered with a layer of relatively flexible or resilient material, such as soft felt, before the textile strands are applied thereto. As shown in Fig. 2, a strip of felt f is first wound spirally of the barrel of the squeeze-roll 35 with its edges abutting to provide a smooth, unbroken surface. The strip of felt has its ends cut to match the spiral winding so that they do not overlap where they terminate at the end-flanges or heads 43 of the roll. The method of cutting, laying and matching the felt strip on the barrel of the roll is more fully described in my companion application for U. S. Letters Patent, Serial No. 18,547, filed concurrently herewith; the present application relating more particularly to the means and mechanism for applying the surface covering to the roll. To apply this surface covering of strands over the layer of felt on the barrel of the roll 1 and worstedmake use of a strand-laying mechanism which is organized with the operating mechanism of the machine as next explained.

The strand-laying mechanism is designed to adapt it to be built into machines of standard type to serve as a permanent partthereof. To support the strand-laying mechanism from the machine I may employ any suitable form of brackets or standards mounted on the main frame thereof. As shown in Figs. 1 and 2, I attach to the endmembers 4 of the size-vat 3 a pair of brackets or arms 50 of inverted L-shape which are fastened in place by means of bolts 5i. At the forward ends of the arms 50 are clongated hubs or bearings 52, in which is journaled a rotatable screw-shaft The screw-shaft 53 is held in its bearings 52 by end-collars 54 secured in place by suitable means such as the set-screws Preferably, the end-collars are formed with rounded flanges 56 providing hand-wheels by means of which the shaft 53 may be rotated manually for a purpose as later explained. The shaft 53 is formed with helical thread-grooves 57 and 58 of rightand left-hand pitch or, in other words, the shaft is cross-threaded along substantially its en tire length.

Slidable longitudinally of the shaft is a sleeve 60 having a. rearwardly-extending arm 61, see Fig. 4, constituting acarriage for carrying the supply of yarn Y, the strands of which are to be laid on the surface of the barrel of the squeeze-rolls and 36. The arm 61 terminates at its rearward end in a fork 62 arranged to straddle a cross-rod 63 which extends between the brackets or arms 50, being secured thereto by means of suitable nuts 64. The crossrod 63 serves as a brace or tie for the arms 50 and preferably carries a tube or sleeve 65 which forms a bearing for the fork 62 of the arm 61, see Fig. 4. The sleeve 65 is usually made of brass to prevent rust or corrosion. Projecting upwardly from the arm 61 is a rod or standard 66 having its lower end bent into an eye 67 which is tened to the arm by means of a bolt 68. The

rod 66 is bent at substantially right-angles at its upper end to provide a spindle 69 for rotatably supporting the yarn-cop or package Y. The cop or package Y is preferably of cylindrical shape, wound with multiple strands of yarn laid in a cross-wind to render the package self supporting without the use of spool flanges. If preferred, however, a spool may be used in place of the cylindrical cop or package Y. Usually the package Y is wound on a cylindrical wooden tube T having an axial bore for receiving the spindle 69 on which the cop turns. The spindle 69 may be set at a slight angle to the horizontal so thatthe package will maintain its position thereon by gravity with the from its opposite end of the tube T bearing against the upright portion of the rod 66. A peripheral groove t is cut in the periphery of the projecting end of the tube T ceive a cord or thong 70'of leather or the like looped over thetube and bearing a weight 71 at its end to cause it to act as a fi, .:tion-brake to control the rotation of the package. As shown in Figs. 2 and a, one end of the cord 70 is fastened in a hole 72 in the rod 66 and the cord leads up over the tube T with the disleweight 71 suspended endz Fastened to a boss 73 on the underside of the arm 61 is a wire strand-guide 74- held in place by a screw The guide 74% has two branches 76 and 77 formed at their ends with loops or pigtails through which the strands 3 lead as they draw down to the squeeze-roll. The upper branch 76 of the guide directs the strands 3 from the periphery of the package Y across the top of the screw-shaft 53 and thence they lead down through the pigtail on the other branch 77 to feed them on to the barrel of the squeeze-roll.

The sliding sleeve 60 is formed with a slot 78 at its center adapted to receive a crescent shaped follower 79, see Figs. 2 and 1, which engages with the thread-grooves 57 and 58 of the screw shaft 53. The follower 79 is carried by a plunger-pin 80 which is slidable in a bearing 81 fastened to a boss 82 on the top of the arm 61 by means of a screw 83. A helical spring 85 surrounding the plunger 80 between its bearing 81 and the follower 7 9 acts to press the latter downward to maintain it in engagement with the threads of the screwshaft 53. The top of the plunger 80 is preferably knurled to provide a finger-hold so that the plunger may be pulled upwardly to disengage the follower 79 from the thread-grooves when it is desired to manually adjust the sleeve along the screw-shaft 53. It will be obvious from the above description that when the shaft 53 is rotated the sleeve 60 will be traversedfirst in one direction and then in the other through the engagement of its follower 79 with the thread-grooves 57 and 58; it bciig understood that when the follower reaches the end of one of the thread-gr0oves it is guided by the curved portion thereof to turn or swivel in its bearing to direct; it into the reverse thread tocause the traverse of the sleeve in the "opposite direction, this being a usual arrangement for traverse-l mechanisms. p

The screw-shaft driven from the squeezeu olls by means of the geared-5 and 16 at their ends which are fast on the

rollshafts

39 and 40, as previously explained. It is to be understoodthat the strand-applying mechanism is both of the squeeze-rolls and 36 and to adapt it to adapted for use with therefore the driving mechanism for the screw-shaft 53 is adjustable in position so that it may be connected to be driven from either of their respective gears 4-5 and 46. For this purpose the driving mechanism for the screw-shaft 53 is carried on an adjustable arm which is pivoted to swing about the axis of the screw-shaft, see Figs. 2 and 3.

Referring to :Fig. 2, the mounting for the arm 88 comprises a separate hub 89 which is rotatable on the shaft 53; The hub 89 is held longitudinallyof the shaft 53 abutting the side of a gear 90 which has its hub 91 secured to the shaft by suitable means such as a set-screw 92. The gear 90 is made in the form of a sprocket to adapt it to be driven by a chain 93 passing over a second sprocket 9%. The sprocket 94 is fast on the hub of a gear 95 which is journaled on a stud 96 carried at the end of the arm 88. The gear 95 is adapted to mesh with the gear at the end of the roll 35 in one instz .e and in the other with the gear 46 on the roll 36,.see particularly F 3. The stud 96 forming the journal for the gear 95 extends through the arm 88 and screws into a handle 97 which serves as a convenient means for manually shifting the arm 88. The handle 97 is scored with a groove 98 to adapt it to receive a wirehool: 99 which is sprung over the shaft 39 or the shaft 10, as the case may be, to hold the gear 95 in mesh with the respective driving gear on one or the other of the squeeze-

rolls

35, 36.

.Referring now to Fig. 2, the hub 89 is held against the side of the gear 90 by a collar 103 secured to the shaft 53 by suitable means such *as theset-serew 104. A portion of the hub 89 is turned down orreduced in diameter at 105 to provide'a bearing fora slotted portion 106 of the arm 88 see Fig. 3. As shown int-his view the arm 88 is widened throughout substantially half of its length and provided with the longitudinal slot 107 which fits the reduced portion of the hub 89. On the hub 89 is'a boss 108 from which extends a rod 109 held therein by means of a set-. crew 110 shown in Fig. 3. The arm 88 is provided on its side with a. lug or hearing 111 which is bored to receive the rod 109 to adapt it to slide therein. One side of the rod 109 is slotted at 112 and a thumb-screw 113 screwed through the side of the lug 111 is adapted to bind against the slotted portion to hold the rod from sliding in the lug. lVhen the thumb-screw 11-3 released the arm 88 may he slid as a whole on its hub 89, whereby to lengthen or shorten the distance between the gear 95 and shaft 53 in accordance with require ments to engage the gear with one or the other of the gears 45,46. After the gear 95 has been brought into mesh with the drivinggear on theppropriate squeeze-roll Cl l the arm is held in its adjusted position by tightening the thumb-screw 113 against the rod 109 to prevent further sliding movement.

In order to compensate for the change in.

relation between the sprockets 90 and 9% during the adjustment of the arm 88 and the consequent tightening or slackening of the chain 93, I provide an idler-sprocket 11a at the upper end of the arm. The idlersprocket 114: is journaled on a stud 115 at one end of a lever 116 which is pivoted at 117 to the upper end of the arm 88. A spring 120 is anchored to the arm 88 at 121 with its opposite end connected to the end of the lever 116. The spring 120 acts to rock the lever 116 to maintain the sprocket 11% under tension whereby to take up the slack in the chain 93.

The method of operation of my improved rollcovering means as employed on a slasher section having a. plurality of squeeze-rolls is as next explained. For covering the first roll 35 the strand-laying mechanism is arranged as illustrated in Figs. 1 and 2, and shown by dotted lines in Fig. 3. That is to say, the arm 88 is drawn out or lengthened by releasing the thumbscrew 113 and sliding the arm on its hub 89. After the arm has been lengthened sufficiently to bring the gear 95 in mesh with the gear 15 on the roll 35 the tlnnnb-screw 113 is tightened against the rod 109 to hold the arm rigid with its pivot. The hook 99 on the handle 97 is then hooked around the roll-shaft 39, as shown in Figs. 1 and 2. to hold the gear 95 in mesh with the gear L at the end of the roll 35. The tape of strands'y from the multiplewound package of yarn Y is then led through the pigtail-guides on the branches 76 and 77, as shown in Fig. a, and thence drawn down to the barrel of the roll 35 and the ends secured thereto.

ll. has been stated that the barrel. of the roll 35 is usually covered with a strip of felt f wound spirally thereof with its ends matched to provide a smooth surface without overlapping seams, but in some cases this felt covering may be omitted. In starting to wind the outer covermg of strands on the squeezeroll the traverse-carriage or sleeve 60 is first adjusted in position at one end of the screw-shaft 53. Usually the winding is started at the right-hand side of the machine, viewed as in Fig. 2, and by lifting the rod or pin 80 to release the follower 79 the sleeve may be slid along the shaft to engage the follower with the end of the screw-threads. This adjustment of the sleeve 60 will bring the strand guide 74 into position with its pigtail yarnguides directly over the end of the barrel of the roll 35, the ends of the strands 2 being attached to the barrel at this point. Usually the ends of the strip of felt f are attached. to the metal barrel of the roll 35 by means of tacks driven into wooden blocks set into holes at the ends of the barrel and the ends of the strands i/ may be secured in the same manner.

WVhen power is applied to the machine through the drive-shaft 16 the pinion will drive the gears 11 and 12 in the direction indicated by the arrow at in Fig. 1. The gear 11 will therefore transmit rotation to the gears 9 and 10 on the size-rolls 7 and 8 to turn the latter in the direction indicated by arrows b. It has been explained that the squeeze-rolls and 36 are mounted to slide in their

bearings

41 and 42 so that their peripheries bear on the surface of the size-rolls 7 and 8 under the weight of the squeezerolls. Through this frictional contact between the surfaces of the cooperating size-rolls and squeeze-rolls the squeezerolls will be driven in the direction indicated by the arrows 0 in Fig. 1. As the roll 36 is turned in this direction the tape of yarns 1 leading thereto will be wound on to its barrel in the manner illustrated in Fig. 2. and meanwhile, the gear 45 on the squeeze-roll 35 will drive the gear 95 on the arm 88. The gear 95 transmits motion through its sprocket 94 and the chain 93 to drive the sprocket 90 which is fast on the screwshaft is thus rotated at a relatively slow rate of speed and the engagen'ient of the follower 79 with its threads causes the sleeve to be traversed therealong. That is to say, when the screw-shaft 53 is rotated in the direction indicated by the arrow d in Fig. l the follower 79 engaging the left-hand thread-groove 58 on the shaft causes the sleeve 60 to be propelled to the left as viewed in Fig. 2. The sleeve 60 and the yarn-supply carrier will thus be caused to traverse slowly along the screw-shaft 53 to cause the tape of strands y to be fed toward the left-hand end of the squeeze-roll The traverse 0f the sleeve 60 is timed to lay the tape or band of strands l in a spiral or helix-with the strands closely adjacent and substantially covering the barrel of the roll. The length of the threaded portion of the screw-shaft 53 is so proportioned that when the follower 7 9 reaches the end of the threads the strand-guide will be just above the end of the roll 35 so that the tape of strands will be laid close up to the end-head or flange 4.3 of the roll. At this point the follower 79 feeds through the curved end-portion of the thread-groove and is directed into the right-hand groove 57. Therefore, as the shaft 53 continues to turn the sleeve 60 will be carried back in the opposite direction and the strand-guide 74 is thus caused to feed the strands toward the right-hand end of the roll. The strands of yarn or other material may thus be laid on to the barrel of the roll in another layer The screw-shaft 52 i Ill) ' gear 46 with .under power and the strands guided by the traverse-means as beforeeX-' and the operation may be continued to aply as many layers tothe roll as required; l Vhen the last layer is completed the end of the tape of strandsis cut from the supply and fastened tethe roll in any suitable manner.

After the surface covering has been applied to the first squeeze-roll 35, the finishing-roll 36 is covered in the same manner by adjusting the strand-applying mechanism to the position shown in full lines in Fig. 3. For this purpose the arm 88 is shortened'by releasing the tlnimb-screw 113 and sliding the arm on its hub 89. After "the gear 95 has been set in position engaging the gear 416 on the shaft 40 of the roll 36 the thumbscrew 113 is tightened against the rod 109 and the hook 99 connected withthe shaft 4-0 to hold the gears in mesh. The tape of yarn strands g is then led down tothe barrel of the roll 36, secured thereto adjacent one of the end-heads, and the traverse of the sleeve 60 started atthe appropriate end of .the screw-shaft The turning-of the the roll36 drives-the gear 95, sprocket Stand chain 93 to drive thegear 90 to rotate the shaft 53,and the sleeve 60 is thus traversed in the manner as before described to feed the strands onto the barrel of the roll in as many'layers as required.

It has been explained that the copper drum or barrel-of the squeeze-roll is 'preforably first covered with a spirally wound strip of felt or like resilient material before the outer covering of yarn is'iaid thereover. In some cases, however, where a'harder, less flexible covering is desired the yarn'mayb'e wound directly onto the metal barrel of the roll without the yieldable base. In either res e the method of adjusting the machine and operating it to traverse the strands to lay them on the roll is the same. It is-tobe understood that the felt base is appl'ied'to the roll before the machine placedin operation for slashing. -Usnailythe machine is driven in low gear and the strip of felt guided on to the roll byhand, and after hasbeen tacked in place the yarn'strands are wound thereover with the machine operating automatically plained. The'initial covering of strands is usually applied to the roll beforethe slashina operation is started,'but it is to be particularly noted "that the outer covering of strandsmaybe renewed at any time during the normal operation of'the machine while thoslashi'ng operation is taking place. In fact, it is the preferred method to apply the strand covering while the machine is op warp "passing there-' erating to slash the through.

It has beenexplained that the warp yarns w in the'formofa sheet are fed into the machine over squeeze-roll, which the guide-rolls '19 and 20,

thence passed down under the innnersionroll and led up over the first size-roll 7 and then across the .top of the second sizeroll 8. As the warp is thus drawn through the machine it is immersed in the starch or sizing-flnid S in the tank or vat 3 and as it passes over the rotating-drums ,or rolls 7 and 8 the squeeze-rolfs 35 and 36 bear down against the drums to workthe fluid into the yarn while squeezing out all surplus fluid before the warp passesout ofthe machine. Ithas been demonstrated that with my improved rolls covered with strands as herein described the action of the rolls on (the warp yarns has a very beneficialetl'cct. This is due to the fact that the coils of yarn on the squeeze-roll coincide substantially with the parallel arrangement of the yarns in the warp whereby the surface of the roll conforms more'closely to the surface of the warp. The roll is preferably covered with a number of strands approximately eqnal to the number of yarns in .the warp and 1 hence the windingson the surface of the squeeze-roll have, a tendency to separate the yarns in the warp and to knead and work the size into the yarns on the sides thereof to effect a more thorough, sizing of the warp. Furtl1er11'i0re,"tlie surface .of the may be described as more or less corrugated due toflits make-up of alarge number of strands, has a combined squeezing and combing action on the warp yarns tending to comb out and straighten the fibers and tolay them more smoothly in place, and also a cleaning action to brush ofl any dirt or foreign matter. .Moreover, as the surface of the 1011 conforms more nearly 'to the surface of the 'warpthere will be less tendency to flatten the warp yarns and hence the yarns emerge from the sizingprocess in a smoother, rounder state without being fiattened or disturbed in twist.

. By applying the outer covering to the roll with continuous strands wound on to its barrel the surface of the roll is made exactly COllCQDtl'lC with its axis so that there are no. hi'g'h andlow points. This results in a more even pressure ofthe squeezea'oll on the Warp during the continuous rotation thereof, the roll having no tendency to rise-and fallas is the case where its periphery eccentricwithrespectto its axis. i r

As another advantage of the present im-' proved roll-covering there are no s ams, bnnches'or protnberances on the surface. of, the roll as is the case with a roll covered with blankets. 'Heretofore the common practice has been to recover the roll with a blanket of woven material-wrapped therearound. )It is obvious that a roll covered with a fabric blanketwill not'have a surface concentric withjits axis and hence: the roll will rotateout of true with a rising and falling'motion asit bea-rs on the warp. This luU causes an uneven squeezing pressure so that the warp is not uniformly treated throughout its entire length. Furthermore, a blanket-wrapped roll has a lapped seam extending across its length formed by the edge of the blanket and consequently each time the roll makes a complete rotation this seam or ridge will leave a mark across the warp. The cross-threads of the fabric blanket are also apt to indent the warp, but with my improved covering there are no ridges, seams, or protuberances liable to mark the yarns being treated.

As a further improvement my present rollcovering is much more economical both in first cost and as regards its durability or wearing qualities. Moreover, it can be applied to the roll without particular skill or expel-mess on the part of the operator and hence eliminates the chance of poor workmanship. Its use also eliminates the hand labor and time required for manually covering a roll with blankets and effects substantial economies in this respect.

As a still further economy the present improved roll-covering will wear longer than a blanket covering and may be renewed when required without stripping off the worn covering. That is to say, the strand-covering on the roll may be applied while the slashing operation is being carried on so that there is no loss of production due to idle machinery. Both the front-roll and the back-roll may be covered during the operation of the machine, as the invention provides for adjustment of the strand applying device or traverse-mechanism from .one roll to the other as required. It is therefore only necessary to remove the rolls from the machine after long periods of use when the outer covering has been renewed to such an extent that it has entirely filled the space between the end-flanges or spool-heads. This condition occurs only after the inner felt-covering has become worn or hardened to such an extent that it needs renewing, generally at intervals of from six months to a year, dependent upon the time it takes for acid fumes from various compounds used in the size to eat into the surface of the roll. When this occurs the roll is taken out of the machine and its barrel trued up in a lathe and coated with white lead. This does not necessarily mean that the machine remains idle, however, because a substitute set of rolls may be kept in reserve and applied to the machine while the defective ones are being made ready for recovering.

The improved strand-applying or covering-means is adapted for universal application to practically all types of slashers and starchers and may be applied to use thereon without change in the basic structure of the machine itself.

The improvement is also adapted for other types of processing machines, such as starchmangles for starchmg or s /img fabrics. Such a type of machine is illustrated in Figs. 5 and 6 of the present drawings. In these views 125 designates the side frames of the machine which support the starch-vat or trough 126. A starch-roll or drum 127 is journaled in bearings at the sides of the starch-vat 126 with its periphery submerged in the fluid therein. Above the roll 12 7 is a squeeze-roll 128 journaled in bearingblocks 129 which slide in vertical ways 123. ressure-screws 130 carrying hand-wheels 1251 are mounted in swiveled bearings one pair of levers 132 which are pivoted in bearings 183 mounted at the top of standards 13% rising from the main frame of the machine. Connected to the outer ends of the levers 132 are pendant rods 135 connected by turn-buckles 136 to rods 13? which are swiveled to lower weight-levers The ,levers 138 carry weight 139 tending to draw the upper levers 192 downward to apply pressure to the screws 130, which, in turn, act through the bearings 129 of the squeeze-roll 128 to cause it to press against the cloth or fabric C passing through the rolls. The cloth 0 delivers from a roll 1 10, passes over and under a series of tensionbars 141, and thence draws betwe en the squeeze-roll 128 and starch roll 12" to a wind-up roll 142. In this type of mach ne the starch-roll 127 is driven from gearing 1 13 and through its contact with the squeezeroll 128 it rotates the latter as the cloth passes therethrough. The squeeze-roll 128 is provided with flanges 1 1 1 and at the outer end of its shaft 145 is a gear 1416. My 1mproved feed-mechanism for applying the strands to the surface or the squeeze-r01 128 is supported from suitable brackets 1 1T attached to the sides of the standards 134. The mechanism of the device is identical with that previously described and comprises the arm 88 carrying the gear 95 at its end adapted to mesh with the gear 146 on the end of the squeeze-roll shaft 145. The gear 95 carries the sprocket 9-1 which drives the gear on the traverseshaft 53 through the medium of the chain 9?).

In thistype of cloth-processing machine there is usually only one set of rolls acting on the fabric so that the covering-mechanism does not require to be shifted to cover the different rolls. However, the mechanism is preferably of the same construction previosuly described to adapt it to be shifted out of the way when it is not required for covering the squeeze-roll. It is to be understood that in the embodiment of the invention as last described the arm 88 may be rocked to shift its gear away from the gears on the squeeze-roll 128, the arm being suspended by any suitable means while the coveringanechanism remains inoperative.

S110 a i r r h-m neleedy n an i ing machines, a rubber-covered roll is em.- ployed to obtain the required. resiliency on its'surface, This type. of roll requires freq nt grin ing or-tlirning surface and as thethicknessof the covering is reduced there is a consequent loss of re? siliency, "With my improved strand-covering the roll does not lose its resiliency during long periods of, use. and its surface maybe renewed when required at much lessYcost than with a rubber covering. Moreover, the rubber covering is liable to. vary in resiliency at different points, that 1s, to have relatively hard and soft spots due to in,- equalities in the mixing or vulcanizing of the rubber, so that the yarn-covering is much superior being, substantially uniform in resiliency also less I tion from exposure to acid. fumes or climatic conditions,

It will be observed that my invention provides a particularly simple and efficient ap- With some methods of prpcessing textiles,

It is tobe understood that Where the covered roll has been herein referred to as a squeezeroll, thisterm isto be considered in a broad sense indicating any type of, processingroll ordruni, The use of my improved roll covering or roll-surfacing apparatus provides for applying the covering to the rolls in the machine and operates in a novel mannor to produce covering which has many features of improvement over the ordinary roll-QOverings, heretofore used,
