Definitions

  • Web material is delivered to a drying and treating zone at a predetermined speed and is caused to travel over rotating reels in the zone while being maintained in a relaxed condition substantially completely free of external tensions. While in the zone, and supported by the reels, the relaxed material is acted upon by more or less discrete streams of air which pass through and about the material to remove moisture therefrom. The streams of air are directed toward the material in such a Way that the material is acted upon intermittently and is agitated or caused to flutter in a manner such that highly efficient drying of the material is realized, while at the same time the material is conditioned and treated by reason of the substantial agitation thereof.
  • a plurality of rotating reels are provided in the treating zone. These reels are rotated so that their surfaces are caused ,to move at a predetermined speed, which is somewhat slower than the speed at which the material is delivered thereto, enabling the material moving over the surfaces to be completely relaxed lengthwise and accommodating substantial shrinkage of the material.
  • Streams of air, moving at relatively high velocity are directed toward the rotating reels at spaced inter vals, as the fabric moves over the reel surfaces, to effect a desirable agitation or fluttering of the material.
  • An important, advantageous feature of the invention resides in the provision of transfer means for causing the material to move throughout at least a portion of its path through the drying and treating zdne and from one rotating reel to another by the action on the material of streams of air.
  • transfer means for causing the material to move throughout at least a portion of its path through the drying and treating zdne and from one rotating reel to another by the action on the material of streams of air.
  • ice is passed through a transition zone, in which the material is agitated and urged along its path by appropriately directed air streams.
  • the material is advantageously transferred from one reel to another within the treating zone and from the last of such moving surfaces to a removing carrier or conveyor by the action on said material of properly directed streams of air.
  • the material is transferred, within the treating zone, from one surface or reel to another, the material is rearranged, assuring that all portions of the material are properly exposed during the traverse of the treating zone.
  • material may be threaded through a rather complex treating path and around drier reels in an entirely automatic manner, so that short pieces of material, such as individual garments, for example, may be delivered individually to the treating zone and will pass therethrough without difiiculty.
  • separate pieces or webs may be passed through the treating zone side by side Without difficulty, notwithstanding that the different pieces may be subject to different amounts of shrinkage'
  • Another aspect of the invention resides in the provision of an improved method and means for treating tubular knitted material comprising the spreading and steaming of the material to shorten the fabric and set its width, followed by the drying of the material, in a completely relaxed and tension-free state, in the manner described.
  • the combination treatment results in a superior conditioning of the material, provides a finished material having a practical minimum of residual slninkage, and permits of accurate presetting of the fabric width at the spread-er, since little, if any, change in width takes place in the treating zone of the drier.
  • the invention also conemplates the advantageous combination treatment of knit materials, which includes the steps of spreading the mate.- rial, impregnating it with a resin, and drying and curing the material in the manner before described to provide a superior finished material having substantial dimensional stability.
  • FIG. 1 is an elevational view, in cross section, of a web treating apparatus incorporating features of the invention
  • FIG. 2 is a cross-sectional view taken generally along line 2-2 of FIG. 1;
  • FIG. 3 is an enlarged, fragmentary, cross-sectional view taken generally along line 3-3 of FIG. 2;
  • FIGS. 4 and 5 are simplified, schematic representations of a combination treating system, including means for impregnating and drying a plurality of parallel strings of material, which may have different characteristics;
  • FIG. 6 is a simplified, schematic representation of a typical treating system according to the invention, incorporating means for spreading and steaming the material and then drying it.
  • Drying and treating according to the invention is accomplished by delivering Web material, such as a fabric A,
  • a conveyor B which carries the material into :a treating zone.
  • the material is picked up by streams of air and by that means transferred to a rotating reel C.
  • a rotating reel C As the material moves around the reel C, it is subjected to the action of discrete, high velocity air streams, which flutter the material and remove moisture therefrom.
  • the material is then picked up again by air streams, fluttered and rearranged, and transferred to a subsequent rotating reel D, where the opposite side of the fabric is subjected to the action of discrete, high velocity air streams.
  • the material is again picked up by air streams and transferred to a conveyor E, for conveyance through a cooling zone F and to a folder, for example.
  • the material is overfed onto the first reel C, and the entire drying operation is characterized by a complete lack of tension on the material.
  • Advantageous treatment of the material is realized 'by the fluttering of the material on the reels and the transfer of material onto, between and from the reels by air streams, which permits rearrangement and readjustment of the material to accommodate any shrinkage.
  • the invention contemplates that, at least in most cases, treatment in the drier will follow a prior specific treatment which, in combination with the improved drying treatment, results in a superior conditioning of the material.
  • One such prior treatment used particularly in the processing of tubular knit material comprises spreading and steaming of the material and delivering the thus treated material to the new drier means.
  • Another advantageous prior treatment involves directing wet material successively through a spreader, to set the width of the material, a first pair of rolls, to remove excess moisture, a resin dip, to impregnate the material, and a second pair of rolls, to remove excess resin, after which the material is delivered to the new drying means.
  • the combined treatment including the drying, may be carried out simultaneously with a plurality of parallel strings of material, each passing over the same drier reels, substantially regardless of the individual shrinkage characteristics of the individual strings. This is made possible by the fact that the air transfer and fluttering of the material provides for the accommodation of shrinkage independently of the rotational speed or speeds of the drier reels.
  • the improved drying and treating apparatus of FIGS. 13 comprises a housing 16 of generally cubic form including front and back walls 11, 12, top wall 13 and side walls 14, 15. Mounted within the housing 11) are reels 16, -17, which are advantageously of relatively large diameter and may be mounted one above the other.
  • the reels 16, 17 may be of substantial width, as indicated in FIG. 2 and, in the illustrated arrangement, are provided with outer walls or surfaces (as indicated at 16) formed of a mesh material such as expanded metal.
  • Substantially surrounding the upper reel 16 is a duct or header 118 having a plurality of spaced slots 19 therein disposed in generally parallel relation to the axis of the reel.
  • the slots 19 may be formed by bending elongated tabs of the header wall toward the center of the reel to define elongated but otherwise restricted outlets or nozzles, through which air, maintained under pressure within the header 18, may be discharged at relatively high velocity toward the outer surface of the reel.
  • the slots or nozzles 19 are advantageously spaced radially from the reel surface a distance in the order of 1 /2" and are spaced apart a distance on the order of 2" to 3".
  • the nozzles 19 eXt md i a Series ar Ild t 4 upper portion of the reel 16, covering an arc in the order of 240.
  • the nozzles 21 extend in a series around the reel 17 over an arc in the order of 330.
  • the material entering the housing is directed onto the surface of the upper reel 16, which is driven to rotate in a counterclockwise direction, and is carried about the reel.
  • the material passes around a substantial portion of the outer surface of the reel 16 and is then directed downwardly onto the surface of the second reel 17, which is driven to rotate in a clockwise direction.
  • the material then travels around the reel 17, whereupon it is directed through an exit opening generally indicated by the numeral 24.
  • the material 22 is delivered into the housing 10, which forms a treating zone, by means of a conveyor belt 25, which takes the material, either in the form of individual pieces of one or more continuous webs, from a supply and carries it to and through a pair of rolls 26, 27 forming an air seal.
  • the belt 25 then carries the material toward but not onto the surface of the upper reel 16.
  • an outlet nozzle 28 (FIG. 3) is provided in the header 18 in a position to direct a relatively high velocity stream of air along the upper surface of the material 22, in a relatively narrow space formed between the material and a lower wall 29 0f the header.
  • the nozzle 23 is located adjacent the sealing rolls 26, 27 and is of such size as to provide an air stream of sufficient force to counteract the tendency of air to flow in an opposite direction from the area surrounding the reel. Accordingly, as the material 22 travels along the innermost portions of the feed belt 25 it is urged toward the reel 16 by a relatively high velocity stream of air (e.g., 4000' per minute).
  • the feed belt 25 carries the material 22 to a point adjacent a lower portion of the reel 16.
  • the outer surface of the reel, at that point, is travelling upwardly, because of the direction of rotation of the reel, and means are accordingly provided for directing the material upward and onto the reel surface.
  • the apparatus of the invention includes a nozzle 30 formed in an upper portion of the header 20 adjacent the inner end of the feeding conveyor. As shown in FIG. 3, the nozzle 30 is located below the upper reach of the conveyor belt 25 and is oriented to direct a relatively high velocity stream of air in a generally upward direction and obliquely toward the surface of the reel 16. The stream of air issuing from the nozzle 30 is sufficient to overcome any tendency of air to flow in an opposite direction from the area surrounding the reel and sufficient to urge and direct the material to follow an upward course and move into the annular space between the reel 16 and header 18.
  • nozzle 31 Cooperating with the nozzle 30 is a nozzle 31 provided in the lower part of the upper header 18 and arranged to direct a relatively high velocity stream of air in a generally upward direction and obliquely toward the surface of the reel.
  • the air stream issuing from the nozzle 31 acts upon the top surface of the material, while the stream issuing from the nozzle 30 acts on the lower surface. Accordingly, the two air streams work in concert to direct the material in the manner desired.
  • the apparatus of the invention incorporates walls 32, 33, forming parts of the headers 18, respectively, defining a channel 34 for guiding and directing the material from one reel to the other.
  • a nozzle 35 At the upper end of the channel 34 and on the side thereof opposite that from which the material approaches, there is provided a nozzle 35 from which a relatively high velocity stream of air is directed upwardly and obliquely against the surface of the reel 16. The air stream issuing from the nozzle 35 opposes air which would otherwise flow in an opposite direction from the area surrounding the reel, and tends to flow between the material 22 and the surface of the reel to strip the material away from the reel and direct it into the channel 34.
  • Material directed into the channel 34 is acted upon by a series of nozzles 36, 37 in the walls 32, 33, respectively, which nozzles are directed downwardly and obliquely toward the opposite surfaces of the material. Air issues in relatively high velocity streams from the nozzles 36, 3'7 and directs and urges the material downwardly toward the lower reel 17.
  • a curved deflector plate 38 which deflects air flowing downward through the channel 34, causing it to flow generally tangentially of the reel 17, in the direction of rotation of the reel, into the annular space between the reel and the surrounding header 20.
  • the material 22 is thus directed by the exit air flow from the channel 34 into the annular space surrounding the reel 17 and onto the surface of the reel, the material then having its opposite side exposed and also being shifted and rearranged to assure unitormity of moisture removal.
  • the material then traverses clockwise around the reel, during which time it is acted upon by streams of air issuing from the nozzles 21 in the manner before described.
  • a conveyor belt 39 which passes about a roll 40 mounted adjacent the reel.
  • a nozzle 41 which issues a relatively high velocity stream of air in a generally horizontal direction and obliquely toward the surface of the belt 39.
  • the stream of air thus issued tends to strip the material away from the reel and direct it onto the belt.
  • -A second nozzle 42 directs a relatively high velocity stream of air against a deflector plate 43, causing air to flow in a generally upward direction around the conveyor roll 40, to urge the material in an upward direction toward an inclined wall 44- forming part of the upper header 18.
  • the wall 44 is, in turn, provided with a plurality of nozzles 45 arranged to direct streams of air toward the upper reach of the conveyor belt 39, so that the material is urged against the belt to be carried away thereby.
  • the belt '39 carries the material between a pair of sealing rolls 46, 47 and into a cooling chamber 48.
  • the cooling chamber 48 is (formed in the rear part of the housing 10* and comprises a pair of headers 49, 54) disposed above and below the conveyor belt 39 and provided with nozzles 51 arranged 'to direct streams of cool air upon the material travelling through the zone.
  • the cooling air may be drawn in through a duct 5-2 and directed by a suitable tan into the headers 49,
  • blowers 53,54 for supplying air to the headers 13, 2b, are mounted in the housing '10,
  • blowers receive intake air from chambers '57, 58 located at opposite sides of the housing, and air is supplied to those chambers from large chambers 59, 60 at opposite ends of the reels 16, 17.
  • Suitable heaters 62, 63 separate chambers 59, 57 and 6t 58, so that air is supplied to the blowers at the desired temperature.
  • a small percentage of the air is continuously exhausted from the chambers 59, 60, through duct means 64, to remove moisture from the system and makeup air is supplied, at least in part, through ducts 65 discharging over the bearings of the blowers 5'3, 54, all as described in greater detail in the before-mentioned oopending application.
  • the material within the treating zone i.e., between the conveyors 25, 39
  • the reels: 16, I17 are rotated at such a speed, in relation to the speed at which material is fed by the conveyor 25, as-to provide tor overteeding of the material onto the reels, even taking into account shrinkage of the material during treating.
  • the speed of the exit conveyor is set to operate at a speed sufiiciently lower than the speed at which material is fed to accommodate shrinkage in the material and to avoid the application of any lengthwise tension.
  • the feed conveyor, reels 16, '17 and removing conveyor may be connected in a simple, direct drive relation, each operating at an appropriate speed with respect to the other.
  • the material leaving the exit conveyor 39 passes around a dancer roll 66, which controls the speed of subsequent processing equipment, such as a folder (not shown). If the loop 68 of material passing around the dancer 66 tends to shorten, the speed of the folder is decreased slightly, and vice versa.
  • discrete, relatively high velocity streams of air which cause the material to be agitated or fluttered.
  • Such fluttering action has substantial advantages, in that the material is constantly shifting its positions on the supporting reels to promote greater uniformity of drying, greater drying efficiency is realized through freer circulation of the heated air, andcertain stresses in the material are relieved in a uniform and highly elfective manner. The latter is particularly important in connection with the treatment of knit materials.
  • the fiuttering action described in the foregoing para-- graph maybe enhanced, in some instances, by the use of reels having substantially imperforate outer surfaces, and the use of such reels may promote the transfer of heat to the material in a desired manner.
  • reels having open mesh material for their outer walls were found to be desirable.
  • the apparatus is entirely self-threading, by reason of the provision or strategically located air nozzles for guiding the material along the desired path. Accordingly, material may be fed into the apparatus in short pieces, such as individual garments, by merely delivering the pieces to the feeding conveyor 25.
  • the apparatus of the invention is thus ideally suited for use in commercial Laundries, for example, as well as for use in connection with the treatment of substantial lengths of web material.
  • Another important advantage of the improved arrangement is that separate webs or strings of material may be fed into the apparatus in side-by-side relation in an advantageous manner. Although this has been accomplished in the past, by maintaining controlled tension on separate strings passing over the same reels, the improved arrangement affords more satisfactory results. However, with the improved apparatus the material is maintained completely relaxed and the rotational speed of the reels does not directly effect the condition of the material, at least in respect of its lengthwise tension.
  • material may be subjected to a combined treatment, to condition the material and stabilize it dimensionally.
  • a combined treatment is illustrated in FIG. 6, wherein tubular knitted material, in single or multiple strings, is spread and steamed before being delivered to the new drier.
  • the spreading and steaming apparatus illustrated generally at G, may be of any suitable design, such apparatus being well known in the art.
  • the fabric is pulled or otherwise cause to pass over a spreading frame '70, which distends the fabric widthwise, substantially to the desired finished width.
  • the fabric is then steamed 'while in spread condition, as by steamers '71, to impart thereto substantial dimensional stability, at least in respect of the width dimension.
  • the fabric treated and stabilized in this manner is then delivered to the drier, generally indicated at 72. in FIG. 6, where it is dried and further treated as before described.
  • the finished product is found to have superior dimensional stability as well as other desirable characteristics.
  • FIGS. 4 and 5 Another advantageous combination treatment is illustrated generally in FIGS. 4 and 5, wherein the fabric is first spread, immersed while in a moistened condition in a stabilizing resin, and then dried and treated as previously described.
  • the entire treatment may be carried out to advantage with parallel strings of material running side by side, although single strings may be processed where desirable or expedient.
  • resin impregnated fabric is dried and aired in distinct steps or operations.
  • the capacity of the drier is such that drying and airing occur in sequence in a single pass.
  • the apparatus of FIGS. 4 and 5 advantageously includes spreading and impregnating equipment of the type described and claimed in the S. C'ohn et a1.
  • the apparatus includes sidc-by-side spreader mechanisms 72, 73, arranged to receive wet material from supply boxes 74, 75, the material being drawn through poteyes 76, 77. The material is carried over the spreaders at two levels, as shown in FIG. 5,
