Definitions

  • ABSTRACT This invention relates to apparatus for performing socalled needling operations on textile goods, which apparatus is characterized by the fact that it comprises a needle support member having a multiplicity of felting needles affixed thereto, the long axes of which are oriented substantially normal to the surface of said member, and an associated backing member to support the textile material against the forces experienced during the needling operation, which backing member has a surface comprising pressure-tolerant, laterally displaceable, elongated members which are affixed at one end to the surface of the backing member and have their long axes oriented substantially normal to the surface of said backing member; said needle support member and said backing member each being so structured as to travel repeatedly along a closed travel path each aggregating 360 of angular change and being so positioned with respect to each other that at least at one point along their paths of travel, portions of said needles reside among said elongated members.
  • the batt of fibers may be supported on a backing scrim, which typically may be an open-weave mesh fabric made in the traditional manner of textile manufacturing. Such a combination, with the fiber batt facing the needle board of the needling machine, is passed beneath the needle board, to which are affixed a multiplicity of needles.
  • the needle board reciprocates upward and downward by means of driven connecting rods, thereby producing the plunging action which, because of the barbed configuration of the needles, causes interlocking entanglement of the fibers with each other and with the backing scrim, thereby giving the textile product structural and mechanical integrity and an acceptable degree of fiber retention.
  • United States Patents which disclose such machines: Stone, U.S. Pat. No. 2,177,604; Walsh, et al., U.S. Pat. No. Re. 21,890; Marshall, U.S. Pat. No. 2,959,509; Chase, U.S. Pat. No. 1,742,133; and Chase U.S. Pat. No. 1,745,739.
  • Textile products made in accordance with these needling techniques have been found particularly useful in the field of papermakers felts where large numbers of fibers must be incorporated into the felt in order to provide the degree of loft, resiliency, and structural integrity that is required to render them useful in the environment of the papermaking machine.
  • the production of needled textile products made by the previously known techniques has been relatively slow and, in addition, the mechanical problems involved in the construction and operation of the associated machinery have been substantial, primarily because of the reciprocal motion and the great weight and inertia attendant to making the apparatus sufficiently strong and rigid to withstand the high forces experienced in the needling operation.
  • an apparatus for needling textile goods comprising a needle support member having a multiplicity of felting needles affixed thereto, the long axes of which are oriented substantially normal to the surface of said member, and an associated backing member to support the textile material against the forces experienced during the needling operation, which backing member has a surface comprising pressure-tolerant, laterally displaceable, elongated members which are affixed at one end to the surface of the backing member and have their long axes oriented substantially normal to the surface of said backing member; said needle support member and said backing member each being so structured as to travel repeatedly through a closed path of travel, and being so positioned with respect to each other that at least at one point along their paths of travel said needles reside among said elongated members.

  • FIG. 3a is a graphic representation of prior art apparatus.
  • FIG. 1 there is illustrated a textile needling machine embodying the present invention, comprising a needle support member 12 and an associ ated backing member 14.
  • members 12 and 14 are depicted as rolls.
  • carrier roll 16 the purposes of which are hereinafter described, although it will be clear that the use'of such a carrier roll with the present invention is-optional.
  • the needle roll 12 comprises a roll body 18 of typical, known per se, cylindrical form, to the surface of which is affixed, by known techniques, such as gluing with adhesives, or mechanical affixation, or welding, brazing, or the like, a multiplicity of needles 20 of any of a wide variety of constructions and designs which are known per se in the textile needling art.
  • the associated backing roll 14 comprises a roll body 22, to the surface of which is affixed a multiplicity of elongated members 32 which have one of their ends affixed to the backing roll body 22 and which are characterized by being able substantially to retain their shape and orientation under the forces delivered to them in their axial direction (which characteristic is referred to herein as pressure-tolerant), and yet are laterally displaceable; that is susceptible to being moved from side to side around their fixed ends acting as pivots.
  • So called card wire well known in the textile arts, is suitable for this use and possesses the foregoing structural features. It comprises a card wire structure 29 of the type illustrated in FIG.
  • a sheet-like member 30 made from textile goods, rubber, heavy plastic material, and the like, from one surface of which project a multiplicity of cut wire members 32 made from material such as bronze, steel, plastics, synthetic materials, or the like, typically of a diameter of about 0.08 cm, and in length about 2.5 cm, the outermost ends of which occupy a plane substantially parallel to the surface of the supporting back member 30.
  • the elongated members 32 of such a structure are free to bend or pivot about points 34; that is, the point at which each emerges from the upper plane of the backing member 30, so that as portions of a needle 20 penetrate among the members 32, such portions may move relative to the elongated members 32, and the elongated members are free to deflect sidewards to give such penetrating portions of the needle freedom to so pass unobstructed.
  • the cut wire members 32 are sufficiently rigid to support the pressures imparted by such things as a fabric being processed without substantially losing their shape or orientation, not only against the normal tensions and operationsl forces herein contemplated, but also against the forces applied as the fabric moves through the point of closure between the needle roll 12 and the backing roll 14 wherein the needles 20 on the needle roll 12 are caused to be plunged through and extracted from the fabric being processed.
  • that portion of the needle which is in contact with the felt, the backing material, and the felt travel at the same linear velocity, measured along what has been designated in FIG. 3 as the X axis, at least at the point where the needle roll and backing material are closest.
  • FIG. 3 where there is shown a graphic illustration of a single needle so positioned relative to the felt 33 and an associated card wire structure 29, the needle and card wire structure moving from left to right such that at a given posi tion A, the needle 20 begins to enter felt being needle.
  • Position C is the position at which the portion of the needle 20 embedded in felt 33, the backing material 29 and the felt 33 will be traveling at the same linear velocity along the X axis.
  • the needling sequence continues to position E where the needle 20 is withdrawn completely from the felt 33. Throughout the needling sequence the cut wire members 32 substantially retain their shape and orientation under the axially oriented or vertical forces imparted during the needling process.
  • elongated members 32 are susceptible to being moved from side to side around their fixed ends 34 acting as pivots. For example, at position A, the needle tip 35 has begun to penetrate the region occupied by the felt 33. As the combination continues to move from left to right as shown in FIG. 3, penetration of the needle 20 through the felt 33 is substantially complete by the time the combination has reached position B at which position the elongated wire member 32 may be caused to bend as a result of the impingement upon wire member 32 by needle 20. The force imparted upon the needle by the felt will cause the needle 20 to deflect. At position B the angular displacement of the needle 20 relative to the plane of the felt 33 is in a direction opposite that of the direction of movement of felt 33.
  • the magnitude of the deflecting force on the needle 20 is a function of roll diameter and depth of needle penetration.
  • the force and therefore needle deflection can be reduced by increasing the diameter of the needle roll or the associated backing roll or both rolls.
  • the end of the needle 20 which extends through felt 33 may impinge upon the bend other elongated wire members 32 and will begin to straighten out such that at position C it will return to its normal orientation. Similarly, the previously deflected wire members 32 will spring back to their normal orientation.
  • the needle 20 begins to withdraw from the felt 33, the bending or an gular displacement of the needle 20 relative to the plane of the felt 33 now being in the same direction as that in which felt 33 is moving.
  • end of needle 20 which extends through felt 33 may impinge upon and bend other elongated wire members 32 and will again begin to straighten out such that at position E it will have sprung back to its normal orientation. Similarly, the previously deflected wire members 32 will spring back to their normal orientation.
  • the elongated members 32 of the card wire underlying the felt 33 must be free to move laterally to accommodate the sweep of the needle tip region.
  • FIG. 3a where it may be seen that if a perforated backing plate where used as in prior art devices, it would be necessary to have the angular displacement of the needles take place about a pivot point 43 that is substantially in the mid-plane 45 of the backing plate 47, since otherwise, the perforated portion 48 of the backing plate 47 would have to be substantially larger, with a consequent reduction in the ability of the backing plate to withstand the pressure forces imparted during the needling sequence.
  • the backing member 29 of the present invention provides a system of holes which, unlike those in a backing plate, move to accommodate the angular sweep of the needle tips.
  • the card wire member can be made to pass through an arcuate path to address the on-coming needles as, for example, by being placed around the circumference of a roll.
  • the needle roll 12 and backing roll 14 are so positioned with respect to each other that at least a portion of the needles 20 on the needle roll 12 occupy the general region also occupied by the elongated members 32 on the surface of the backing roll 14.
  • one or both of the roll axes are movable so that the rolls may be positioned closer together or farther apart.
  • fibers 44 are laid onto the outer surface of a papermakers felt 42 which has been rendered into the form of an endless belt, by a fiber-laying device 46 of any of a multitude of well-known designs such as a carder, batt former, layer combination, or a blown fiber source, and is positioned about the backing roll 14 and, in the case illustrated in FIG. 1, about a carrier roll 16.
  • the backing or the carrier roll, or the needle roll, or even an associated slack takeup roll, or any combination of them, may be driven to cause the rolls to revolve and, therefore, the fabric 42 to move.
  • the fabric 42 will be carried through the nip formed between the backing roll 14 and the needle roll 12 such that the needles 20 on the needle roll 12 will be caused to progressively plunge into and through and be extracted from the papermarkers felt 42.
  • the felt it is possible to subject the felt to a substantial number of needling passes in a very short length of time, because experiments have demonstrated that the felt may be run through the needling nip at speeds in excess of about 300 meters per minute.
  • the diameters of the elongated members 32 of the card wire structure 29 are small, and since, in terms of needling practice, these diameters are analogous to the land areas between the perforated holes on the backing plate of a standard reciprocating needle machine, it is possible to have a much more dense concentration of needles on the surface of the needle roll than can be achieved on a standard needle board.
  • the practical maximum density of needles on a needle board as used in the industry is about 8,303/sg. meter, whereas experimental machines embodying the present invention have been used having a needle density of 13,830/sq. meter and it is thought that this density might even be increased.
  • it is possible to perform a high-speed needling operation from which the quality of needling and the product produced thereby is very high and is clearly acceptable to meet the standards of such difficult and demanding products as papermakers felts.
  • backing roll needle roll diameter combinations may be operative in the practice of the present invention, it is desirable although not required for both rolls to have large diameters; e.g., on the order of cm or more, since, obviously, the greater the diameter of one or both of these rolls, the less relative movement there is between a given needle point residing in the region of the card wire members 32, and this further reduces the working of the needles through the elimination of lateral moments of force even through it should be understood that the degree of working is smaller diameters is within acceptable limits since there will not be an untoward amount of needle fatigue, bending, or breaking. Accordingly, backing roll needle roll combinations having smaller diameters may also be used. For example, backing roll needle roll combinations of as small as 30 cm and 120 cm, respectively, have been shown to be operative in the practice of the present invention. It also may be desirable for the diameter of the backing roll to be equal to the diameter of the needle roll.
  • EXAMPLE A machine was constructed having a needle roll 122 cm in diameter, to the surface of which were fitted felting needles which were equilaterally triangular in crosssection, having barbs at the corners of the triangles, to a needle density of 15 needles per 10 sq. cm of roll face.
  • the needles were mounted perpendicular to the roll face.
  • Associated wire rolls were fabricated in two different diameters; one 30 cm, and one 122 cm. On both of these wire rolls the roll face was covered with card wire, the heights of the wire filaments of which were approximately 2.5 cm in length. In this piece of equipment, only the card wire roll was driven by an outside source. The depth of needle penetration was adjusted as desired by changing the center-to-center distance between the rolls.
  • the felt was positioned about the card wire roll and over a third idler roll which was movable to facilitate taking up slack in the felt.
  • Several felt samples were needled on this machine, using both the 122 cm and the 30 cm wire roll.
  • the product of the present invention appeared to have several different characteristics over those produced on standard reciprocating needle looms. For example, one difference was in the apparent size of the holes left in the felt by penetration of the individual needles. Although the needle holes in the felt produced on the machine of the present invention appear slightly larger than those left by reciprocating needle looms, apparently due to the changing angular path followed by the needles during penetration, it was also noticed that the apparent bulk density of the felts produced on the machine made in accordance with the present invention was somewhat less than that produced by a reciprocating needle loom.
  • the following table shows the measured vertical flow rate of such felts in liters per minute at various mechanical loadings for various felt thicknesses made both on a reciprocating needle loom and on the machine embodying the present invention.
  • the paths of travel may not be the true circles as in the case of the needle roll and the backing roll being revolving cylinders, but instead may be elliptical or other geometrically regular or even irregular closed loops in cross-section. It is also within the contemplation of the present invention to have a multiplicity of needle rolls in tandem arrayed around around a common backing roll, whereby several combinations of needle types and- /or needling depths may be accommodated sequentially on a given fabric in a single set up.
